the AC compressor on my daughter's 944S seeps oil/freon from the center seam of the compressor - otherwise works fine - so, time to change the o-rings and the front seal. The process for changing the seal is described in the service manual, along with special tools to use. I have a reasonable home machine shop (4 ft metal lathe, horiz/vertical mill, etc) and can easily make most of the stuff, but there is a puller for removing the clutch assembly that threads into the hub of the pulley - I can't (easily) cut metric threads, so I either need to buy this tool, find out what the threads are so I can find something with the right threads, or borrow one.

I found this tool

http://www.handsontools.com/store-products...nt%3E_1066.html

but I have no way to find out if it right for my compressor (I have the 10P15E compressor) - does anyone know if this tool fits? or where to find a tool that fits, or even, what threads are required so I can cut them myself?? Or (joy of joy) anyone near los angeles that would care to lend me a set of the tools- that would be amazing -

I can, of course, pull the assembly several other ways, but the way in the manual seems like the best - after all, it's the "factory way".

following up, I found a listing of needed tools for Porsche (and other) AC service here

http://www.mastercool.com/manual/form10.pdf

and that list confirms that the above tool is the right one - so I guess I answered part of my own question-

but has anyone else done this type of rebuild? any comments or hints? it ought to be easy, but who knows?

oh, I'm ordering the kit of O-rings from here polarbearinc.com

Been there, done that. Was a waste of time and money. The compressor is old and has worn parts, not just seals. Rebuilt from my dealer was just as much as a quality rebuilt anywhere else and the dealer is not somebody you have never seen over the internet. I got lucky when I ordered the compressor from the dealer, a brand new one came. Same price.

I am real pickey about A/C. As in it better work, its been hot in Texas and everywhere else for that matter.

I took a deep breath and took it to my Indy and had the compressor, dryer, condensor, hoses, and expansion valve replaced. It works and it's all warrantied.

following up -

original problem was caused when someone (before me) welded a repair on the threaded "ear" that supports the front of the compressor and hold it to the mounting bracket - the heat from the weld weakened an o-ring in the adapter plate that adapts the compressor body to the hose set - anyway, I decided to replace the front seal also - had some "challenges" doing that due to my own attempt at taking a short cut - broke the new seal, put the old one back - original leak fixed, but old seal leaks slowly - pulled AC pump back out and sent to PolarBear to install a new seal (they charge $80 to reseal a compressor - after the repair (my repair) compressor cooled well, so a rebuilt was not needed - no sign of wear or scoring inside either. We shall see how this turns out when compressor comes back from PolarBear - meanwhile, see separate thread about timing belt problem - that has me really baffled
