I figured I'd start a new thread again, the other one had a bunch of topics..
I want to adapt my Mastercool tool kit so I can remove and install the clutch on this compressor. I have the older version, apparently, and this compressor has metric threads. Based on the location of the clutch and shaft threads, it is difficult to measure with my thread gauge.. Can someone tell me what threads are on the clutch and on the shaft, so I can modify my existing installer / remover? This is only going to be used one time, I can't justify 90 bucks for the tools, I have a full machine shop at work, can make my own. Please reply, and thank you.
Sorry can't help with this one.
Why not simply go by the local AZ location and see if they have the correct clutch removal tool....should be able to 'rent' for a small charge. If not AZ, check the other retail locations....may save some time and have the correct tool. Be sure to measure the air gap with a non metallic feeler gauge.
The strongest reason for the people to retain the right to keep and bear arms is, as a last resort, to protect themselves against tyranny in government.
thanks for the replies guys, I was hesitant to ask to be honest, I felt like I was maybe pushing my luck with the advice. FWIW, the mastercool tool set I have I purchased through this site some time ago - or actually a family member did, it ended up under the Xmas tree.. The remover tool, could simply get the correct metric bolt that would thread into the clutch, then, during lunch at my workplace, chuck it up in the lathe and drill and tap it to the same thread as the mastercool installer has. The installer, same idea, but in reverse so to speak.. yes, all of this would be a tad time consuming, but so is this long term project, it's just another step in the process, and I get a ton of satisfaction doing this. I have drawers of homemade pullers, seal installers, spring compressors, etc., we maintain all of our own custom-built machinery (designed and built by us) at work, fully loaded machine shop at my disposal on site.. making these tools would be fun.. Either way, thanks for the help... and if anyone knows the thread size, pass it on to me, otherwise I'll measure them the best I can, hit the hardware store, hope I guess correctly..
depending on how old the compressor is (year of the car) there may be a nut on the shaft, remove that to measure the thread size.. Just a thought, new GM's don't use the nut...Older ones should still have them on the shaft..
Freedoms just another word for nothing left to lose
Why is it important to use a non metallic feeler gauge? The reason I ask is I used a metal one when replacing the shaft seal on my a6. ;-)
The list of mistakes I made is getting longer.
In case anyone is interested, I got the thread sizes.. The compressor shaft is 9MM 1.25 pitch, so I bought a 7 dollar tap and made a piece to add to my installer. The clutch is 22MM 1.5 pitch, which is rather odd.. However, it just so happens that a track bolt from a caterpillar dozer is the same size. Go figure. (that information thanks to google) So, $2.15 at my local cat dealer, got my bolt, drilled and tapped that to accept my remover center piece, done deal. So I have under 10 bucks and about 30 minutes into my mastercool 91269 kit to retro it to remove and reinstall my clutch. These thread sizes might be something to remember, maybe..
Thanks for all the help!
not that relevant my post here, just wanted to let you know that after looking around for one day, this was the exact information i was looking for... will have to replace the clutch coil on my 96 eldorado and there's the choice between metric and standard when it comes to remove/install tools, so i just didn't want to buy both (time question). thanks for that data!
