Doesn't it just make your whole day when you go to a swap meet and come home with something like this?

Thanks-This led me to do a little more oil filter research.The flatter cover with the lettering closer to the center arroused my curiosity.

The 1950 was the first year of the blue and orange filter.(factory installed were always black).The 1950 version was AC number SC 649 and Chevrolet number 5572299.This was used thru 1952.My 1950 has one that was installed when new -I have the shop order for it.

1953-54 AC SC650 & Chev. 5572380 were the numbers used.They looked from what I recall the same as previous years but???

The 1955-58 filters were SC 655 and 5573580.They also looked like the previous filters but no longer had the drain plug on the bottom and were clamped to the rear of the manifold as the new air cleaner was forward.This also required different length lines.Also Tee fitting may have been different as the oil sending unit threaded in (1/8" pipe thread) rather than the gauge oil line.I have a new in the box version.

!959 is AC SC659-Chev. 5575218.

1960-62 is Ac SC660-Chev. 5576528....

1970 book lists AC SC353???

The later books list the filters (for replacement) as fitting from 1955-62.
Also 1962 was the first year the passenger cars came from the factory with a (black) filter.

Now from my observation the pictured filter is a late version.First clue is the white box.The earlier ones came in a blue box.Also has the flatter cover which was a 1959 change -as listed in parts book.This must be the year the printing was brought in closer to the center bolt rather than being on the much more outter raised rim of the earlier years.

The numbers on or a view of the numbered end of the box would be welcomed.Will all be helpful in advising in the future dance

I say that's a nice find and it would make more than just one day good...that's worth several days, maybe couple of weeks!

My pleasure to post another view. The information on the box is: SC-655 and under that number is: 5573580. The information on the cap: “Use AC P-115” and “Type S-6 AC Oil Filter”.

Based upon chevgene’s posting, and in anticipation of additional information, I plan to move this string from “Show and Tell” into the Tech Talk for easy reference to this excellent line of information.

Thank you Ray,
Just when I thought that I had the filter differences verified you completely put me back on square one.

AC oil filters have proven to be very difficult to identify as to the minor changes made to them each year.They were never classified as an accessory by Chevrolet but available as a parts installation kit from Chevrolet and -or AC.Various pictures found of the from both Chevrolet an AC are incorrect as often they didn't bother to up date a picture and a filter would be pictured for years after changes were made.Trying to determine what is correct by looking at a certain year car is also misleading as many times the filter was installed after the car was a few years old.

My SC655 filter has the same numbers as yours (on box).The instruction sheet for mine was copyrighted in Dec.1954 and instructions are listed for 1955 6 cyl.Has the cone shaped lid and dark blue box.Your numbers are the same but has the flat lid -which is listed as being new in 1959.The SC655 was still listed in my 1959 parts book and was discontinued in the early '60's.Did they use the newer style lid on the 655's made after 1958???-Or did the change take place in 1957 or 58??

Another interesting thing found.In the 1957 assembly manual the cone lid is shown and the return line on the bottom of the filter had an angle fitting so the line goes out away from the exhaust pipe and curves around to the bottom of the block.The 1955 version I have has the line dropping straight down-causing it to come much closer to the (hot) exhaust pipe.The page has a 6-20-56 up date for the factory installation of the optional filter.

Well back to square one for now :confused: :confused:

The S-6 is in great shape. Nice find Ray. But that leads me to a question. Does anyone know where I can purchase a new decal for the lid of
either the AC L-1 or an AC L-4 Oil Filter? The decals on the lids are both curved and say "AC Kleer Kleen Oil Filter L-1 (or L-4)"

toolman,
Not sure of the quality of the decals, (I've not rec'd any from this supplier) but National Chevy Assoc. has them in their catalog....info on the decals...."AC Kleer Kleen Oil Filter L-4" is item number 206 and the oil filter canister ring decal is item 225 with costs of $3 and $2, respectively.
The internet site is www.nationalchevyparts.com and go to online catalog...it will even show you a picture of the decals. Hope this helps.

Thanks for the tip of National Chevy Assoc. They have the exact shape and size of the AC L-4 Oil Filter decal. The one that they have looks orange in color with black lettering. The one on my AC L-4 is engine gray background with black lettering. I will email them to see if the gray color is available.
Thanks again for the heads up.

The 1942 AC filter manual I have shows the decal on the side of the housing and its larger and square.Looks to be almost 3" by 4".

Both the AC L-1 and the AC L-4 that I own have a decal on the lid that is contoured / curved like the S-6 decals that I have seen. On the side of the cansiter for both the L-1 and the L-4 is a round "AC" decal that is about 2" in diameter. Neither of them have the rectangular decal like is available from several of the vendors. To add confusion to the issue, the original box shows the rectangular decal on the outside of the box, with no similar decal on the metal oil filter
housing that is inside the box.

I believe that there is no positive way to determine all the AC filter changes made from year to year.

Well - at least the judges won't know either.

Gene,
Here's a couple of bits of info concerning oil filter units from Chevrolet to add to the mix. The first one is for the passenger car (dated 12/54) and the 2nd is for a truck (dated 5/54). I shrunk these down to reduce their size for viewing, but if anyone would like a full-size copy emailed to them, let me know.

why does the first diagram (car) indicate tipping the top of the canister inboard, while the second (truck) indicates the opposite?..

and, is mounting the canister at an incline an option to clearance obstructions or is it required for proper operation?..

Darn good question(s) Kepi.

And another thought on Gene's comment......

The 'problem' is some judges may (will ??) think they know and they could be wrong!! You'd hope a judge wouldn't make a deduction if he didn't really know which was which.

Frankly this appears to be one of the most confusing aspects of the 40's - 50's cars.

yes, it is bill, as evidenced by the many inconclusive discussions that have gone before here...I'm with you...

and if gene says one can't be sure - and in the absence of new, reliable information - it will probably remain a nebulous issue...

Bowtie Bob-The instructions you posted are for 1955 and up.Note the oil pressure sender switch on the passenger car sheet.The 1955 and later mounted behind the carburetor with the inlet line in the position shown.The 1954 and older had the filter mounted ahead of the carb. and the inlet line entered to the rear of the canister.Around 1960 the shape of the cover changed from the cone shape in the center to a more rounded top and less ridge around the outter part of the cover.See picture Ray posted above.That filter is a 1960 and up version (because of the cover) made to be installed on a 1955-58 (by AC number)

The 1947 thru 1962 canister looked the same as what is shown - except the 1947 was not clamped to the manifold but fastened in the center using intake to exhaust manifold bolts and carb. mounting stud to hold brakket in place.

In the later years mounting of the canister became a real problem as the power brake unit on a 6 cylinder interfered with the filter and a special bracket was required.

To farther complicate the issue often filters were installed after the car was a few years old so a later filter can often be found on an earlier car as they all could be "made" to fit.

Frams were so common for later installations that many think they were "correct"

I have a new 1955-58 Ac filter with the instructions for good reference as well as a 1950 dealer installed AC on my 1950.

Here is a page with some info provided by Chevgene a while back on AC Oil Filter Installation Instructions 1940 - 1955

Does a 1938 Chevy have an oil filter? Is there any instructions for installing one? Thanks for any info.

The 1938 Chevrolet did not have a filter as standard equipment.The AC would have been considered a correct installation if its they type sold back in 1938.The later AC as Ray has pictured could be installed and are the most easy one to find.
I have had my '39 for over 40,000 miles and 33 years and never thought of installing a filter.Just change oil a little more often.n oil bath air cleaner, which was an option in 1938, would be a better investment if the car is driven on dusty roads.

You can encounter a mess of hassles by adding an oil filter. People bitching about it being "wrong" whether it is or not. Leaks. And more...... Some feel it's best to just leave well enough alone. And follow Gene's advice. (Frankly that's always a good idea.)

Incidentally, interesting to note you changed your "line" to grab second gear. Seems like somebody advised you to do that.

Take Care....

The filling station has two different AC oil filter decals that you are looking for. They are about 4 bucks each. Good quality, I bought a couple a while back.

Could you post any pictures of those NOS units you have? Like the units or the boxes or any instalation instructions that you may have with them.
