Not sure this the correct group.
I wanted to see if anyone knows what this is. I got it with a bucket of VW odds and ends. I didn’t know what it is. A/C adapter?
Thanks.

That was my first thought as well. However, most AC units on VWs run of the crankshaft, and there is a considerable difference in diameter between the fan / gen pulley and the AC pulley as shown below.

It may be an AC pulley, but I have never seen one like that on a Type 1, 3, and 4 engine before.

That looks like a nightmare to work on. Appears you have to remove the A/C compressor if you want to do anything. I'd be curious to drive a Bug with A/C. I've driven some 4 cylinders where you couldn't have the A/C on when pulling up a hill or away from a dead stop. One was a Toyota Tercel. I called it "White Lightning". It had to be one of the slowest cars on the planet. Nobody wanted to be behind me going up a hill.

My 1970 had the dealer-added AC, and tough to get to #3 and #4 lugs, worse then with leaded gas fouling them up. I cut out some metal and made an access panel to access those under the fender. Yes, that 1600cc S engine was a little sluggish using the AC, tons better once I built and installed 1835cc DP engine.

To R&R the engine, or to change the generator, had to unbolt the AC compressor and move it to the side. I eventually bought 2-piece AC compressor mounts for a 1973, that was better and easier. I also made an accessory pulley so I didn't need to use special-size VW dealer AC belts.

When they first put AC on VWs, which was a VW certified dealer add on they used the York Piston style compressor.

These WERE a nightmare to work on the engine (I have), plus they pulled so much power from the engine, that many of the engine had a short life span. However the new rotary style compressors like a Sanden does not put nearly the load on the engine. I have one on my 2L Squareback, and I don't see much notable difference, on or off when I am climbing a grade. Don't know about a stock 1600 though.

I think you have 2 different ones there, the cupped one looks like type 1, the other could be type 3.

My 1970 had a Tecumseh compressor on it. That dealer-added unit was DPD from Texas. All I have left on it is the underdash evaporator box; I removed the clogged evaporator core, so that's basically a fan these days.

I’ve looked at AC pictures and still can’t figure out how these two work. I’ll keep searching. Thanks

I don't think it's a VW part at all, no keyway on either part.

They bolt on over the OG pulley, usually using a longer bolt. The type 1 version often had tabs that engaged the puller slots in a standard crank pulley but I think some just relied on the bolt being torqued well, not sure on the type 3 one.

There's not alot in the archives for beetle, but read the installation instructions and see if you recognize it.

Keep in mind there were at least 3 different "official VWOA" A/C suppliers and all their stuff was different, those instructions may not apply to the parts you have.

That is very true. I know that its not for a type 4 engine, because I installed AC in my Type 4 powered Squareback. I also have the AC installation manuals for 1967 and 1970 Type 3s. Each of them show a different AC pulley. However, the one that you are holding in your hand, "looks" like the one in the 1967 Type 3 manual. I also have the later style Type 3 AC pulley in one of my sheds. When I get a chance, Ill see if it is like the one that has "pegs" on it.

I found my newer Type 3 AC pulley, and it doesn't look like either of yours. As I mentioned, The one you were holding "looks" like a early T3 pulley, but no dimensions were given in the manual. You might try searching in the gallery, or classifieds sections for AC Pulley, and see if anything looks like a match.
