My uncle had an 70s John Deere tractor with an A6 and I'm pretty sure it cycled but can't say with absolute certainty. Also we had a '79 Ford LTD with an A6. Again I'm pretty sure it cycled but can't say with absolute certainty.

I removed the POA valve and put a cycling switch kit on a '67 Firebird and a '71 C10 for others, both with A6 compressors, and as far as I know both are still running fine. I know a lot of people don't like those kits but both of my customers were happy.

Now with all that said, I would not put a new A6 on anything. I would swap to a Sanden. I think efficiency and life is much improved from what you can get from any A6 you can buy today. Any cycling is not an issue.

I probably have 10 old A6s that are going into the next scrap metal run. Just no demand and too much downside to putting a used one on anything. One of them is original from a '68 Camaro but what good is it?

I stand corrected. If I ever saw one, I don't (obviously) remember.
