Where Was Oil Filter Located On 1955 Corvette V8

Restoring a Stovebolt to correct, original specs can be a formidible task -- especially when one gets down to the detail items that tin can brand or pause a run at Carlisle Gold. One of those details, the optional externally mounted oil filters, is one of those details that, because of a definite lack of comprehensive research, is often left to a "all-time guess." Well, no more! Your oil filter questions can be settled equally Pat Doonan answers ...

The Dandy Oil Filter Debate
By Pat Doonan "ddautoparts" D & D Antique Auto Parts Bolter # 19190 1959 Chevrolet 3100 Panel truck 1941 Chevrolet Suburban		December 22, 2008

Sharing the Information Currently, I am in the process of procuring parts for a 1941 Chevrolet Suburban I ain and plan on restoring one-time in the about future. One of the items I accept been searching for is the correct oil filter assembly for this vehicle. I know which one I need, but I accept found through my search, that everyone I talk to has a different version of what's correct for it. To add together to the problem, in many cases the original Chevrolet Parts Books used alone tin get out you with a pretty large gray fuzzy void, particularly if y'all don't have the original AC filter catalogs to fill in the blanks. Surely other folks out at that place are facing a similar trouble, or have at least questioned it. So I decided to endeavor to come up with a definitive reply on what is and is not correct for 1930's to early 1960's Chevrolet 6 cylinder cars and trucks. Fortunately, being in the NOS parts business organisation, I have Accumulated well over 50 original Chevrolet Master Parts books from 1912 through 1982; nearly a dozen original AC oil filter catalogs; miscellaneous pieces of original Air-conditioning literature, and many NOS Ac oil filter assemblies and original Instruction Sheets. Hopefully, I'll be able to clear upward what is truly correct for the 1930'southward through 1960's Chevy'south to make your restoration a little easier (or little harder, depending on the rarity of the one you demand for your vehicle). Please conduct in mind though, that even with all of the info I take, there are notwithstanding some of those grayness areas left apropos what is truly correct for some of the years listed below, especially 1930'due south models. Some data is improve than none. So I'll share what I do have. I'll have it year past year to effort to sort out the whole thing and make it easier to refer to. This reference is strictly for Chevrolet. If you need some info on other GM makes, drop me an e-mail and I'll be happy to share what I know.

Introduction

It is important to annotation that oil filter assemblies were non standard equipment on pre-1963 Chevrolet cars and trucks. Chevrolet offered oil filter units equally an RPO (Regular Production Pick), or every bit a dealer installed item bachelor through the GM Parts Partitioning. In addition to the Air conditioning units supplied to Chevrolet, Air conditioning made many other styles and models available through AC distributors and United Motors Service. I will be discussing many of these Air-conditioning units equally they pertain to passenger cars and calorie-free / medium duty trucks. I will not go into the heavy duty units over two quarts, simply if y'all demand data on those units, delight contact me and I'll be happy to share that as well.

In order to assist with the identification of various units I volition be roofing, I have included pictures and references to those pictures throughout this article. To maintain every bit high a degree of accuracy as possible, all photographs of actual units shown are of NOS oil filters and fitting kits. None accept been repainted or restored in any mode.

If at that place'due south anyone out in that location with boosted original literature that I don't have, or NOS units that they would like to share pictures of to assist shed more than lite on this, please experience costless to contact me so i can mail it here for everyone.

Permit us begin ...

1933-1938

L-1 Series (center opening type)
Dissever from what is listed in the Chevrolet Master Parts Catalogs, AC offered the 50-1 heart opening blazon filter (image #1) as a new installation on about American automobiles. It could exist purchased for Chevrolet besides through Ac and United Motors Service dealers. It used a replaceable chemical element under part number L-11.

Due west-1 Series
The 1936 Chevrolet Master Parts book states the filter unit for all 1933-36 models except CA, CC, DC & EC is listed as part number 601465, and states that a dissimilar oil distributor valve cap (#376843) and gasket (#835905) are required with this unit when used on 1933-34 models. The new valve cap had a threaded hole to accommodate the oil filter line plumbing equipment.

In that aforementioned 1936 book, it mentions some other unit of measurement being used every bit a "replacement unit" for 1933-36 models CB, DB, O, P, EA, ED, EB, Q & R, merely gives no role number.

The 1938 book lists office number 852902 as that replacement unit for 1933-36 models CB, DB, O, P, EA, ED, EB, Q, & R. From what I can determine from the books, the 601465 unit of measurement probably included all of the fittings, hoses and mounting bracket. No mention is made as to the AC model number of the unit supplied.

The only inkling as to the model of this filter is that the AC oil filter manuals I accept, list AC filter W-one equally being the original equipment filter for those 1933-36 models. It was then superceded past filter number Westward-21 (bottom left on this image).

1939-1946

During the war, vehicles supplied to the armed services used the military standard senior and junior type filters. For obvious reasons I'm going to encompass units for noncombatant rider cars and trucks only here.

S-1 Series
The 1940 Chevrolet Parts Book states the filter associates used for these models was part number 1503611. Introduced in 1939, and used only through 1941, it was an Ac Due south-one unit which was mounted on the firewall.

Due south-ane filters were supplied in two dissimilar versions. The early version is shown here as the S-one first design and here is another, listed with part numbers. It had a 9" vanquish length, nearly 12" overall length, and used gasket #130. The unit had a rounded cervix at the bottom, and used a T-handle type embrace bolt.

The second pattern type of the South-one unit of measurement first appeared in the Apr 1, 1940 AC Oil Filter Service Manual, (image #five ) but the instructions included with it (run across Education Section below) nonetheless showed the starting time type. The second type had an conical bottom rather than the rounded bottom neck pattern used in the early version. Information technology also used a different diameter gasket and the height cover was retained by a more conventional fashion commodities rather than a T-handle.

I would imagine that depending on inventory levels at Ac at the fourth dimension, and unsold units at the dealerships, it is possible that some first pattern units could have been used also on early 1941 models produced and sold in tardily 1940, especially since the first and second design units used the aforementioned part number, so stock could have been mixed.

The color (of both styles) was an aluminum grey lacquer, and had a black and silver waterslide decal on the side of the shell. Both the early and the late version used Ac Kleer-Kleen type S-11 "igneonite" filter element.  What is an "igneonite" filter you may inquire? (Meet epitome #six ) Well, the 1942 Air-conditioning Oil Filter Service Manual states: "Igneonite is a mineral wool made from rock which is melted and blown into fine strands. This is mixed with a resin binder and molded around a perforated middle core which is first covered with several layers of canton flannel or glass cloth. It contains no clay or fuller's earth." There. Now you know.

The element number inverse to C-113 around 1944, and was a cotton fiber type. Later, the element changed once more to a more modernistic paper type and was sold under Air-conditioning part number P-113.

Although the Chevrolet Master Parts books state the application equally "all," its sales were undoubtedly targeted primarily towards trucks. The Air-conditioning Oil Filter Installation sheets packaged with other smaller chapters models of the time (such as the L-1 & 50-4) instructed the user to use the S-one unit for truck applications.

The S-1 was the simply filter offered through Chevrolet from 1939 to 1941. The 1942 and the 1945 Chevrolet Parts Books do not list a filter available through the dealership at all for 1942 models. Still, AC however offered the S-i, too as the L-1 and 50-4 units for 1940-1942 rider automobile and light truck models through Ac distributors and United Motors Service (shown in the adjacent two sections).

50-ane Serial
Air-conditioning offered several styles of filter for 1939-46 cars and trucks in addition to the S-1 unit described above and sold through Chevrolet dealerships. The redesigned Air-conditioning Kleer-Kleen 50-1 series was offered for Chevrolet passenger cars and light trucks. The new design was a superlative opening unit, rather than a center opening unit.

AC made two different versions of the top opening L-1 series. A drawn shell type, and a welded shell type were both sold nether the L-1 series designation. The fatigued crush type was one piece of stamped steel forced by a plunger through a serial of progressively smaller drawing dies to course the bottom and sides as one unit. The lip under the elevation was the same bore as the beat body. (Meet image #7)

The welded shell type (see image #8 ) was basically ii pieces welded together where the bottom cap met the shell trunk, and the trounce had a  rolled lip under the cover.

Through my research, information technology appears that the welded type was used at first, and by the middle of 1940, the drawn cup fashion was the unit predominantly produced and sold. As with the mid-year change to the S-1 series, it could be entirely possible that some kickoff design L-1 units could take been used on early 1941 vehicles.

The color for both versions was an aluminum gray lacquer, and had a black and argent waterslide decal on the side of the shell. The decals were non the same for both styles though. Looking closely at images #7 and #eight (in a higher place) of two NOS units shows the diction being different in reference to the gasket used.

Both versions were originally supplied with an "igneonite" element, #L-11. Around 1944, it was changed to a cotton element part number C-112, and was again changed to the P-112 paper type years later. Gaskets were different in all three versions produced of the L-1. (Run into image #9 which shows the different gasket part numbers.)

Unlike later on styles of the 1940'due south and 1950's, this filter was not mounted to the intake manifold cantankerous runner frontward, or rear of the manifold rut stove. The Chevrolet Subclass and Plumbing fixtures Kit (Kit four) mounted straight to the face of the manifold heat stove. The top portion of the bracket had a single hole, and the lesser portion had two holes. The L.H. carburetor stud nut and the two bolts attaching the intake manifold to the exhaust manifold closest to the drivers side firewall were removed, the bracket fastened in place, and the nut and bolts were re-fastened. The subclass had a slot for a i" wide strap which clamped the filter unit to the bracket. (Encounter image #10 - part #'s 853534 & 853434 and the 50-1 Instruction Canvas plant at the end of this article.)

Although the Southward-1 unit was what was offered through the Chevrolet Parts Departments, the Fifty-1 and Fifty-4 series (discussed in the next section) were bachelor through Ac distributors and United Motors Service. Starting in 1941, AC offered a unlike style bracket for utilise on trucks only (except COE models) from 1937 to 1946 under part number four-t (L-1/L-4 mounting bracket for truck -- image # 11 & image # 12) when using an 50-1 or Fifty-iv unit. It attached to the horn mount on the manifold in the front end, and to the intake/frazzle manifold at the rear.

L-4 Series
The L-4 series was first introduced in 1940. It had a fatigued vanquish and was a smaller version of the 50-1 series, existence the same diameter, simply shorter in length. In the 1941 AC Oil Filter Catalog, it was advertised equally "a low priced filter for small passenger cars" (come across image #thirteen for an example of a unit with 1940 - early on 1941 labeling, color scheme and decals).

The original L-4 series shown in this picture was finished in aluminum lacquer and had a black and silver "Kleer-Kleen" decal on the beat with the "50-4" model designation and instructions on when to change the oil. The after type was painted with a gray lacquer rather than aluminum, and had a 2 ½" round blackness and yellow "Ac Oil Filter" decal on the shell (see paradigm #xiv).

After versions actualization effectually 1946 were exactly the aforementioned in construction, just there was a slight change in the Air-conditioning waterslide decal (see image #15).

Both of the later type units that were painted gray had an Fifty-4 decal on the top. (Image #16 shows the L-4 second type color scheme.)

Unlike later styles of the 1940's and 1950's, this filter was not mounted to the intake manifold cross runner forward, or rear of the manifold oestrus stove. Information technology used the same brackets as the L-1 which mounted directly to the face of the manifold heat stove. The top portion of the bracket had a single pigsty, and the bottom portion had two holes. The Fifty.H. carburetor stud nut and the ii bolts attaching the intake manifold to the exhaust manifold closest to the drivers side firewall were removed, the bracket attached in place, and the nut and bolts were re-attached. The bracket had a slot for a 1" broad strap which clamped the filter unit of measurement to the bracket. (Come across paradigm #10 - role #'s 853534 & 853434)

The L-4 used an "igneonite" element, under part number Fifty-xiv. The cotton version appeared around 1944 under part number C-110, and was finally changed to a P-110 paper element.

1946 - 1948

South-2 Serial
The 1946 Chevrolet Chief Parts catalog shows the part number for 1946 as beingness 1504439. It as well states that information technology is to be used for 1942 models. Technically it would be a retrofit, and not be period correct for a 1942, since information technology did not exist at that time. Then, but to throw one more than snag in all of this, there is no filter listed for 1947 vehicles in the 1947 catalog. Even so, it still lists the 1504439 as existence the unit for 1942-46 models though. The 1948 Chevrolet catalog lists the 1504439 unit as existence the correct one for 1947 and then I'm going to assume it was some sort of fault that 1 did non appear in the 1947 book and the oversight was corrected in the 1948 book.  Sometimes ya merely gotta love GM.....

1 thing is for sure though. The 1504439 unit of measurement is an AC model Due south-two Filter Associates, which was the replacement for the at present discontinued S-1 unit of measurement. Although the books say "all except COE,"  information technology is geared more towards trucks I believe, rather than the passenger cars, merely because of the size of the unit. The S-2 unit of measurement is large, and in my opinion existence nearly two quarts, is a little bit of an overkill for car use. It has a peak of eleven 5/eight", which was a petty taller than information technology'southward predecessor, the S-one, and the O.D. was v" diameter, as opposed to the S-ane'south diameter of 4 5/8". The Chevrolet-purchased unit was mounted to the firewall with the 2 straps supplied with it. The standard version supplied by AC also mounted to the firewall with the two straps, or on the intake manifold runner by adding the correct bracket fix, which was the same as the ane used for the S-6 models described below.

The original 1946 unit was grayness, and had a 2 ½" diameter yellow and black "Air-conditioning Oil Filter" decal on the beat. (Come across image # 17 - original gray color scheme used to July 1947)

By mid year 1947, the color scheme changed from all greyness to yellow with a black acme. (see prototype # 18 - South-two yellow & blackness colour scheme used from July 1947 through 1949; and image #nineteen - S-two Kleer-Kleen decal used from 1946 through 1949)

The S-2 series was used upwardly to 1962 as an alternative higher chapters unit of measurement to the S-6 for larger trucks and busses. In 1950 the color scheme changed, to having an orangish hat and bluish body.

The S-two unit initially used a C-25 filter chemical element, which was changed to a C-117, (cotton) and finally to P-117 (paper) element.

L-5 Series
The L-five serial was offered through AC and was only used from 1945 through 1948. It was never marketed or offered through Chevrolet. It had a larger capacity than, and replaced the L-four unit of measurement, and had a completely different mounting subclass. It could be used on the 1937-1942 models. Merely when information technology was, the mounting subclass location was in a dissimilar location than later years. A apartment bracket was held to the intake manifold heat riser box by ways of ii u-bolts, one on either side of the box. The 2" wide shell bracket was tightened on to the shell, and the whole associates bolted to the flat bracket using two special u-bolts to keep it all together. In 1946, the intake manifold was changed on the Chevrolets, and the threaded pigsty for the wiper vacuum connection was moved from the firewall side of the manifold to the L.H. inner fender side. Because of this, the filter location changed on the 1946 to 1948 models from existence attached to the manifold heat riser box, to just forward of it so it would not interfere with the new vacuum connection location. The color of the 1946 and early 1947 unit was gray, and a 2" diameter yellow and blackness "AC Oil Filter" decal was on the beat out mounting strap, rather than the shell itself (run across paradigm #xx - Fifty-5 gray color scheme prior to mid 1947).

The 1947-48 version had the same decals, just the shell was xanthous with a black superlative. (See image #21 - L-5 with yellow & blackness color scheme used from July 1947 through 1949; and prototype #22 - L-5 black top color scheme used from July 1947 through 1949.)

The L-5 series used a C-111 cotton chemical element initially, and it was later changed to the P-111 paper type.

Due south-six Due south eries
In 1945, the S-6 was introduced for use on civilian passenger cars and trucks and sold through Air conditioning and its distributors. For whatever reason, it was not sold through Chevrolet Parts Departments every bit an canonical Chevrolet dealer item until 1949. Still, from this betoken frontwards, the Due south-6 unit and variations of it would be the filter unit of measurement that would exist used as standard equipment on Chevrolet 6 cylinder engines upwardly to 1963 every bit the L-1, L-iv & Fifty-5 were phased out. Changes through 1949 were mounting subclass configuration, inlet hose location, decals, and color scheme. The S-6 unit had a height of 8 ½" and was 5" in diameter with a filtration rate of 16 gallons per hour. The bracket type was the aforementioned as the L-five unit of measurement, with the simply deviation existence a slightly larger diameter strap to accommodate the larger shell diameter. When used on models prior to 1946 (equally a retrofit), the S-6 unit was clamped to the middle of the oestrus stove by means of 2 special u-bolts. The location was changed to forward of the stove starting in 1946. The reason for the location modify was that the vacuum connectedness fitting on the manifold was at the rear of the heat stove on 1942 models, and on the side of the heat stove starting in 1946.

From its initial release in 1946 to mid-1947, the unit was gray with a yellowish and black Ac decal on the lid, and the ii" round yellowish and blackness "Air-conditioning Oil Filter" decal was located on the mounting bracket (see epitome #23 - Due south-6 original gray color scheme used to mid 1947; and epitome #24 - Due south-6 top). The Air conditioning designation for this unit of measurement packaged for installation on Chevrolet's was SC-646.

Starting in July of 1947, AC released the "5 Star Oil Filter Line." The S-six unit remained the same as far every bit size, construction, and mounting brackets. The only difference was the color scheme. The S-half-dozen unit of measurement was no longer painted gray as in the early models. The lid was now painted flat blackness, and the vanquish was a apartment yellow (come across epitome #25 - S-6 yellow & blackness colour scheme used from mid 1947 through 1949).

The lid had the same yellowish and black decal, and the yellow and black two" bore "AC Oil Filter" decal on the beat clamp equally with the greyness 1946 / early1947 units.

The element was a C-115 cotton wool chemical element, later changed to P-115 paper type.

Through my research, i take found that there were iii different coloring and wording schemes on the lid decal that took identify between 1946 and 1949.All three versions are shown below. << click paradigm for larger view >>

A note nigh "Due south-half-dozen" Series filters
When first introduced, the South-six line was a universal filter that covered a wide diverseness of applications, including non-GM vehicles. They could be put on virtually any vehicle equally long every bit the respective bracket and mounting kit was purchased. Starting with the 646 series, the three digit AC office number suffix made a loose reference  to the type and year the filter was first introduced. But you must keep in mind that a new series was not introduced every year. And then some filters carried over for more than one selling season. The prefix (SC) likewise helped announce model and type.

An example follows:

Type SC-650 was an "S" line filter. The "C" denoted it was a tailored kit packaged specifically for Chevrolet applications. (Kits tailor made for Cadillac used a "K"; "P" for Dodge, Chrysler and Plymouth applications; "Chiliad" for Oldsmobile; "F" for Ford; "N" for Nash). The "6" denoted the line type. The "50" established what model yr it was first put into service. And so, SC-650 was an S-vi type, tailor made for Chevrolet, and outset introduced in 1950. This same referencing applied to other types besides, such as the S-2 line.

1949

SC-646 Series
Starting in 1949, the Chevrolet Parts Book begins to offer a little more information on the exact units used by giving the Ac part number. The 1949 Book states that part number 5571614 is an Ac, SC-646 Consummate Unit, and it contains the Southward-6 filter. (See Due south-6 unit description higher up.) First bachelor through AC distributors in 1946, information technology was at present a dealer installed detail for 1949 and could be installed on previous twelvemonth models.

The C-115 cotton element was yet the replacement offered for this unit. The unit all the same mounted the same manner every bit the earlier S-6 units with i bracket on the forrad runner of the intake manifold, and one ii" high strap attaching the shell to the subclass. It also nonetheless retained the xanthous and black color scheme that was used starting in mid 1947.

1950 - 1952

SC-650 Series
The 1950, 1951, and 1952 Chevrolet Parts Book lists the number as existence 5572380. It  states information technology is an Air conditioning type SC-650. The SC-650 was still the basic Southward-six unit, but with several changes. It had the mounting subclass spot welded to the beat, rather than having a split strap and mounting bracket. The most notable departure was the absence of a drain plug. From this point on, the drain plug would be omitted in all South-6 units. The shell colour was now blue. The lid was the same as earlier units, just the color was at present orangish, and information technology no longer had a decal on it. The "S-six" designation was now silkscreened around the outer border of it, forth with a identify to write the mileage on it when the filter was changed. (See image #29 - 5572380/SC-650 unit of measurement; and prototype #xxx - 5572380/SC-650 top) The whole unit was attached to the forward intake runner by two u-bolts. The u-bolts now used to attach the units were like what is used on a muffler clamp, rather than the special ones used on previous Chevrolet S-six models. (See Didactics Sheets at the end of the article.)

Starting in 1950, the Chevrolet Parts Book shows the P-115 newspaper chemical element, and does not offer the cotton element, although they were however available through AC distributors.

1953 - 1954

SC-653 Serial
For 1953 and 1954, the unit of measurement was redesigned again, and sold under role number 5573017 (see image #31 - 5573017/SC-653).

The 1953 and 1954 Chevrolet Master Parts books for both years country that the unit was now an SC-653 unit. There were major changes to the unit once once more, although the torso itself was the same dimensionally as the 1950-1952 models. The spot welded subclass changed completely. The inlet hose connection was at a slightly dissimilar position in relation to the spot welded bracket than previous models. As far as package contents, the inlet and outlet hoses were each 1" longer than the previous model. The silkscreening on the lid was slightly different. Instead of having a block area to write the mileage in, it now had lines (see prototype #32 - 5573017/sc-653 top).

1955 - 1958

SC-655 Serial
Air-conditioning unit number SC-655 was the next generation of filters in the S-6 series. Introduced in 1955, it went under GM part number 5573580, and was used through 1958. The 1 exception to this is the 1955 Chevrolet 1st Series trucks, which still used the SC-653 AC unit of measurement. The second series trucks used the SC-655. The SC-655 unit of measurement had a different bracket than the earlier units and would be used on all vi cylinder models through 1958 (see image #33).

The twelvemonth 1955 also saw the introduction  of the soon-to-be-famous 265 cubic inch Chevrolet Five-8. The Chevrolet part number was 5573607 for the 8 cylinder model filter used on vehicles without air workout. The Air conditioning model designation for this unit was SC-6558-1 according to the parts books. The Five-8 filter used on models with ac was Chevrolet number 5573919 and was marketed as an Ac SC-6558-a unit of measurement.

Information technology'south interesting to note that the 1955 AC Oil Filter Catalog offers model SC-6558 to fit all V-eight except 4bbl, Corvette, or vehicles with air conditioning, and model SC-6558-x to fit 4bbl, except Corvette or air conditioning. The Air-conditioning Filter Book makes no mention of the "a" suffix model described in the Chevrolet Parts Books.

The 1955 models were the outset and only year the V-8 engine used an optional external oil filter. From 1956 on, all Chevrolet 5-8'south have used an integral cartridge type, or modernistic twenty-four hour period spin on type, while the six cylinder still used the external bolt on Southward-vi exclusively through 1962, and some models to 1963.

Both the 6 cylinder and 8 cylinder units are shown in image #33. The P-115 paper chemical element was used on both 6 and 8 cylinder versions of the filter.

SC-255 Series
Although Chevrolet stopped offering the South-2 series afterwards 1948 and would non officially offer it once again until 1959, it was still bachelor through Air-conditioning. Notwithstanding a two quart unit, information technology went through the same basic changes every bit the Southward-6 line as far as brackets, trunk type, inlet hose location and colour scheme. Paradigm #34 shows the SC-255 series available from 1955 through 1958.

1959

SC-659 Series
The 1959 Chevrolet Parts Book lists this unit of measurement as beingness part number 5575218. It was all the same the tried and true S-6 unit with a few changes. The inlet line was located 180 degrees opposite of the mounting bracket which would be the inner fender side of the filter when installed. (See image #35 - 5575218/SC-659 unit)

The cap was at present slightly shorter in top (see epitome #35 ; and epitome #36 - - 5575218/SC-659 summit) and the stamped depression extending to the sealing lip surface was not as deep or pronounced. The top retaining commodities was also different, equally there was no shoulder under the head as in previous versions. The silkscreened lettering was moved to the angled portion of the top rather than the flat surface right above the gasket sealing expanse. An area to write the mileage when the filter was changed was also eliminated.

This unit still used the P-115 paper element as in past models.

SC-259 Series
In 1948 it was the last year Chevrolet offered a two quart unit according to the Master Parts books until 1959. Nonetheless, the S-two units were even so available through Air conditioning and its distributors after 1948. Starting in 1959, the S-2 was once again offered nether Chevrolet function number 5575217 and carried AC designation AC-259. It was exactly the same as the earlier unit (image #34) except for the fact that the inlet line was 180 degrees reverse of the mounting bracket. It used Air conditioning filter P-117 equally in the earlier units.

1960 - 1963

SC-660 Series
Starting time in 1960, the unit used would at present exist Chevrolet number 5576528, which is AC type SC-660. (See paradigm #37 - 5576528/SC-660 unit of measurement.) This unit was exactly the same as the 1959 model SC-659 in physical appearance and lettering with the exception that the inlet line connection was on the firewall side of the filter (as installed), whereas the 1959 version connected on the inner fender side (every bit installed). The top, and the lettering on information technology was exactly the aforementioned as the 1959 version. (Come across paradigm #36)

The SC-660 filter type was used on the 1960, 1961, and 1962 Chevrolet 235'southward every bit well as the two quart SC-260 unit described below. They were both discontinued for 1963 since the newly introduced Chevrolet 230 cubic inch 6 cylinder engine now used a spin on type element, eliminating the need for this bolt-on type style. The ane exception to this is the 1963 Chevrolet iv wheel drive trucks which retained the 235 engine until mid-year 1963. Once the 235 was finally phased out, so were bolt-on oil filter units for use on Chevrolet cars and trucks from that point forward.

SC-260 Serial
The two quart unit was available through the parts department from 1960 through 1963 under function number 5576615 and Ac designation SC-260. Its appearance was the same as the unit shown in epitome #34 except for the inlet line location, which was on the firewall side of the filter (as installed).

Many of the units I've described hither are all fairly shut in fashion. When looking on eBay, or scrounging effectually at junkyards or car shows trying to find your correct unit, it's piece of cake to go one style mixed up with some other. Many of them look identical. The only way to tell them apart is by size. Image #38 shows many of the one quart units discussed hither, grouped together to give y'all a better thought of the physical size differences betwixt the various types.

Oil Filter Lines

Which oil lines are technically correct is merely about as confusing as the filters themselves. AC changed materials and colors quite often, equally you will see in the example pictures. Image #39 and image #twoscore show hoses from the original Kleer-Kleen line prior to 1947. For the hoses prior to 1947, the part number did not friction match the hose length. For example, hose number 27 was xx" in length. Besides, the two NOS samples shown are encased in different materials. Image #39 is the early fashion cloth braided type hose, and paradigm #40 shows the afterwards manner which had a grayness rubberized or neoprene casing. During that same time period, AC also supplied completely black hoses, too.

Starting in 1947, the part number of the hose was also the length of it. Some hoses supplied were greyness, blackness neoprene, or yellow (see image #18). Most late 1940's hoses came with a plastic band around the hose indicating the function number forth with a yellow and blackness Air conditioning circle logo (see image #41). By the 1950's, all of the hoses were blackness and the logo band was still black and yellow. The merely difference is the box packaging had changed to the double bulls eye logo (encounter image #42). Starting in 1959, they changed from a plastic band to a sticker with a crimson and white AC logo around the hose showing the office number (see epitome #43). Replacement hoses supplied through GM dealerships in GM packaging rather than AC packaging did not have the ring or sticker with the role number of the hose.

I promise this has been of utilize and value to some of you out there. My goal in researching and writing it was that this information should clarify what is and is non correct for our vehicles for those of you like me, who are sticklers for actuality. It would also be squeamish to see this used as an ACCA and VCCA judging assist, as there is no definitive standards out there as to what is and is non correct or adequate.

Some other  reason I was motivated to do this type of research was the fact that many vendors out there are telling people what they take for sale for your vehicle is what is correct for information technology. EBay sellers and bandy see vendors are the world'due south worst at this. Whenever you lot notice an oil filter for sale with these folks, no affair what type, they will commonly say that it's correct for your 1930'southward to 1950's automobile or truck when in most cases, nothing could be further from the truth. In all fairness to these folks, they are not e'er trying to intentionally deceive you then you'll buy from them. They are simply going on what they think is correct or by instructions included with items they're selling. For example, the Due south-vi units i have described above, that were not introduced until the 1940's, have instructions that testify installation dorsum to the 1930's. Although these instructions show this, the units are not correct for the 1930'southward applications since they didn't even exist and so. The way I see it, if you know what'south right, you won't waste material your coin on what's incorrect.

The other problem is that reproduction places perpetuate this thinking. Decals sold through the repro places don't always give the correct yr usage or awarding. Not because they're purposely trying to deceive you, but because they honestly don't know all the facts. I hope this article gives yous those much needed facts.

On the other mitt, despite my arguments on correct vs. wrong, the one thing I demand to stress is that i of the most of import things you can do for your restored Chevrolet Stovebolt 6, is put an oil filter on it. When it comes down to it, whether it'south the correct one, a different year, style, or another aftermarket brand, ultimately information technology really doesn't matter. Simply put one on to assistance protect your engine, and nosotros'll all be able to relish each other'due south vehicles for many years to come.

Questions? Comments? Arguments to the reverse of what'southward written hither? Email me.  I will also exist happy to email copies of the oil filter Instruction Sheets for various Air conditioning units for many GM models and years free of accuse.
