1965 AC Receiver & Dehydrator Assembly #3155342

[Ray K.]

Can anyone tell me if there is supposed to be any part number and/or date code information on an original 1965 AC receiver and dehydrator assembly (#3155342). I can't find or see a date code or part number on it. . . .

And, according the 6th edition technical & judging manual, the inlet & outlet sides are supposed to be marked "EVAP" and "COND" on them, which mine doesn't. It only has the word "IN" marked on one outlet side.

Does anyone know if my receiver & dehydrator is an original, after-market, service replacement, or, from another vehicle?
If it makes a difference, my '65 was a late build, 3rd week of July 1965.

Ray,

I can not provide you with any info about the date code. What I can tell you is that this is not an exclusive Corvette part. My '69 P & A catalog shows application for #3155342 as used for -- 1963 -67 Corvette, 1964 - 67 Chev pass car, 1964 - 67 Chevy II, Chevelle, Camaro, and some 1968-69 light truck models. Just about everything that had an AC system during this time frame used this receiver assembly.

Hi Ray,

The Technical & Judging Manual is correct stating the inlet and outlet should be marked "Evap" and "Cond" on #3155342 receiver/dryers. Lots of prior posts on this subject here in the TDB Archives.

As far as I know, there are no markings stamped into the canister other than the "Evap/Cond". But there is a paper sticker on the bottom of known originals. More than not. I've never come across a legible one that I could cipher. My canister has black over spray on it from prior bodywork. I figure that's where the part number or date code would be found? Anybody got a nice clear one to share with us all here? That would be great!

Your clamp and bolt shown in your 5th shot looks correct (bent over top tab). They're hard to find but not impossible. Your '65 should have 2 clamps/bolts. I'll post some shots from my December '65 built 1966 AC Corvette here then I'll make another post of file NCRS photos of what a real #3155342 dryer looks like along with shots of the paper sticker on original canisters.

Hello Ray,

The next photos are one's I've collected from the NCRS TDB Archives. Thank you all for posting/sharing.

The #3155342 isn't impossible to find. There's one for sale now on that on-line auction site. Not mine. Go there and type in the part number and you'll find it at the top. It's NOS $$$. Nice photos too.

Another option to find a real one would be to contact folks here in NCRS. Pretty sure I've seen some of the guys restore these canisters. They cut them open, replace the desiccant then weld them shut. Eventually I'll be looking for them to do my original. If anyone knows who does this work would you post it on this thread? Maybe they'd sell you an extra they have laying around?

Here come the file shots. Mike

Ray:

I would say your drier is an aftermarket service replacement.

Mike:

Classic Auto Air in Florida, Old Air Products in Texas, and PaceCarJeff on Ebay Stores all manufacture and/or sell rebuilt originals. I personally have used Jeff. At one time he bought from Classic Air, but may have started rebuilding on his own.

1963 AC car driers say IN and OUT. After that is was EVAP and COND.

Thanks Larry,

I've bought stuff from Pacecar Jeff before. I'd rather use him vs. the other folks. Gonna contact him.

In/Out on the '63s? Good to know. So that's why the guy that's selling that NOS #3155342 advertises it as a '64-67 part. Mike

Based on your pictures, I'll say it is a replacement. Here a picture of my July built '65, VIN 2209x Covette's a/c dryer. I've never found any part number on it.

Thanks everyone for your responses & expertise.
I'll start my search for an NOS replacement and keep my fingers crossed that I can find one.

Ray:

Forget NOS and just buy a recently reconditioned original from sources already mentioned. The drier contains a desiccant, and after 50 years of sitting on a shelf (sealed or not) the desiccant is likely bad. Also original drier desiccants are not suitable for R134a, if that is in your plans.
