Wow! How do you get that rusty engine oil dipstick out of that thing?
BTW, I asked Dr. Bill the same question on the fabulous Glenn car when I saw it in person.

I have a green A6 I have posted pictures of before.

However today I spotted one of the mythical '61 Green compressors:

The Stig;

Do post more pictures of it, from more angles, and with less if not no background clutter, if possible.

I have previously posted detailed articles about the FIVE different AC fast idea solenoids before - on the SCG website and and a photo album on the SCG Facebook site. Here is a photo of all five with a brief summary:

1962-63: vacuum-electric "pusher"
1964-65: vacuum-electric "puller"
Late 1965 (and replacement for all earlier): all electric "puller"
1966 single arm all electric "puller"
1967 double arm all electric "puller"

If you can login to the Stock Corvair Website, you can view that article here

If you are on Facebook, you can view that album here

Thanks for all the continuing contributions to this thread! Especially the latest updates on compressors and fast idle solenoids. I did not know the first solenoids were "pushers".

Speaking of A6 compressors, here is a copy of info submitted recently by Steven Barker in another thread here on CC. He shows a quick way to identify a proper compressor back plate that was intended for reverse rotation pumps like the Corvair used. Look for a small hole to signify the correct pump back plate. Back plates are different for a reverse rotation pump because lubrication oil needs to be pumped forward to the front of the pump. If you installed a back plate from another GM application, the compressor would still compress the gas but the lube circuit would fail to function properly.

Had a look at the back plate on the compressor in our car, it doesn't have the hole shown in the pics above and it is labeled for 4lbs of charge (model # 5910486). The clutch engages but it doesn't blow cold, I believe it was retrofitted by a PO. Compressor was off to the side of the engine bay when we got the car. Do all reverse rotation A/C compressors have this hole? The back plate on ours looks different to the pics, it is smooth with no letters cast in it.

As far as I know they do. Pretty sure with the missing ID hole and the R12 charge amount shown at 4 lbs and not 5 lbs. that you likely have an A6 from another GM vehicle or an aftermarket part possibly owing to the back plate with no casting ID.

The unit should still compress the gas properly when run either direction but would eventually fail due to poor lubrication going to the front of the compressor.

It is easy enough to buy the clockwise version.

Which is probably what the previous owner did.

At $500 plus you can sell it and make a buck.

4 lbs was the correct charge for cars with the 1966 style condenser. The compressor label still said 5 lbs in 1966 but was changed to 4 lbs in 1967.

Thanks for the clarification Bill. The model number on the label Si mentions traces back to a Chevelle.

Thank for the feedback guys, I always wanted a Chevelle so looks like at least I have a part of one :-) Before I try and rejuvenate the A/C as-is, might be time to switch to a Sanden compressor. Any thoughts on the SD5 vs SD7? Clarks have a good deal on a used SD5 at the moment, we will be running R12 in the system as we have 15 lbs to use up.

I was asked for more details about the brace used to strengthen the dash where the support gets cut in order to fit the taller climate controls.

Dims shown are not perfect but should be close enough to help you make your own part if needed. I applied masking tape to an OEM brace, marked up the tape and then pulled off the tape and laid it flat to make the drawing.

Thanks Dave --- It's an important part and one of those parts you can make and nobody will ever know it's not a "factory" part.

It's as difficult to find as the front tire bracket that goes in the trunk.

The details are forgotten so many times. I can't count the number of times I've seen an a/c system in the swap meet area and the vendor swears he has a "complete system", only to go through it to find that he's missing a lot of the small details that make for a complete installation.

That is why I advise everybody who is about to remove an a/c system from a parts car to FIRST get the installation instructions from Clark's. That booklet is worth its weight in gold, as it tells you just what to remove, right down to the last fastener. It varies slightly from the factory installation, but is otherwise invaluable beyond belief.

Remember that the devil is in the details, and it's the little things that count. Maybe a bit of cheche there, but so apropos, I'd say.

I installed A/C in my son’s 1965 Monza using those instructions and a “complete system” that I bought from Mike Harrison at the CORSA Carlisle convention. It truly WAS a complete system, including the brace, pipes, clamps, etc. Of course, I cut the holes and brace with saws, not torches.

This bit about having to cut and brace the dash frame always bothered me, though. I found it odd that they developed an “integrated” AC system into the dash but stopped short of designing the dash bracing to accommodate it. I suspect that the AC design came along after they had already designed the dash and they just found it easier to cut and brace it for the small number of cars with AC.
