I've had my AC compressor disconnected all winter because the bearings were making a nasty grinding noise.. I think its the front bearings on the compressor - but could be anything else in there...

So, I'd like to replace the compressor. Looks like a simple job given location and connections.

Anyone have a source for A/C compressors for our cars? Any alternatives or better than others? Rebuilt or new? This would be for R134, obviously.

Thanks!

Avoid York. Sanyo is quite good.

Google Hancock Industries in Abilene, Texas. I've bought a rebuilt compressor from them for non-Porsche cars (also at least two receiver-dryers) and have been happy with their work. Reasonable prices also. No affiliation.

This is what the PO replaced mine with

Jim, thanks for the pics... Looks way different - mainly the locations of the valves...

How does it mount up? Mine has 4 long bolts going thru the top corners of the compressor housing. Is that a custom job?

Thanks

+1 for Hancock.

Looks like they have moved to Austin & changed their name but it's still run by David Hancock

The Sanden 507 was on two different Mercedes I owned. They are nearly bullet proof, and a replacement was $80 the one time I needed one. Prices are up since then, obviously. In the picture I see the steel York adaptor plate below the compressor. It is not clear how this was adapted to the Porsche mounts. The Sanden IIRC is a 5-cylinder swashplate design, and quite smooth. I would still worry about resonances or other vibration problems when changing from something factory-approved. Might work great, but I would not take the risk or the potential hit on resale value for non-original parts.

I have never had good luck with rebuilt compressors. They are more prone to seal leaks, don't seem to perform as well, and have shorter lives than factory-new units. I have always had great success with new compressors. I would purchase a new one, even at double the price. It is worth the difference in the long run.

My dealings w/Hancock were actually on a York to Sanden conversion for my 930 back in '96. They should have everything you need for the conversion. The Sanden is MUCH lighter, quieter & smoother. The York is now a 40+ year design. I had my conversion for two years w/no issues before I sold the car, ymmv.

PS: Forgot to mention, my current car has had a Sanden on it for over 10 years from the PO.

York compressors came on most AC kits for the early 911s. The Sanden came in the box with an adaptor to replace York twin-piston compressors. Yorks vibrate and are heavy. The 5-piston swashplate Sanden is a fine upgrade.

The 964 OEM is Nipondenso, a vane-type compressor which is smoother, quieter and lighter than the 5-piston Sanden. That steel adaptor plate in the picture surely increases net weight. Look at the welded pipes and hose clamps in the picture of the Sanden conversion. Inferior workmanship evident there would steer me away from that car, worrying about what other non-standard repairs were undertaken elsewhere.

Gosh I better junk the car because of the 1/2# extra weight and sloppy workmanship on a 16 year old car

I just removed the whole AC system from my '91 C2. It worked well before removal. I'm turning my C2 into a track car. If you are interested in the compressor just PM me an offer.

if you want a used one i have one from a rs delete.

Sorry, I did not mean to offend. I was correcting the comment that the Sanden is an upgrade for the 964. It is a fine compressor and a nice upgrade for the York-equipped 911s. Hoses and mounting details are a direct fit to any York system.

It appears both the hoses and mounting brackets need to be modified to fit a Sanden to the 964. Nippondensos are expensive, but are light-weight. The sliding-vane design is smoother than the Sanden, which is a piston pump.

The only one Hodyon has is the OE Denso (is that from Nipondenso?) for just over $400. Still beats Perf Products price of $480 or so..

Is this the one I want? No mention of Sanden replacement/etc. York is never mentioned on 964s in my reading..

Thanks
