Has anyone replaced the electric clutch on the air conditioner compressor? If so, how did you do it? I have removed the clutch plate and am down to the electric clutch body. Is there a special puller to use? Thanks in advance.
pullers show up on e-bay every once and a while, but there are several compressors that use similer looking pullers but they are threaded different so make sure the one you are getting is for your application. I need one for an A-6 Harrison (delco) and got two other in the bargin, I thnik one is for the Saab (and others) compressor but haven't looked into it further.
Thanks for the info on clutch replacement. My AC system is fully charged and cooled well until the clutch went out. I have a spare compressor with good clutch and want to remove the good clutch and replace the failed one on my '92 vert without loosing the R12 refrigerant. I'll check with Autozone on their loaner AC clutch removal tool set. How would removing the clutch destroy the shaft seal?
Thanks for the safety goggle suggestion Jim. I wear glasses but will put on safety goggles also before trying this. If I'm not successful and lose the R12, I'll do a R134 conversion.
Removing the clutch shouldn't damage the shaft seal or cause the system to lose pressure as the shaft seal is installed in the nose of the compressor which is attached to the body of the compressor with Allen bolts. The magnetic coil for the clutch is pressed onto the nose. This is assuming you have the Seiko SS170PSS. Just be sure to use eye and hand protection just in case.
The info I supplied in the previous post was in case you were replacing the shaft seal.
Thanks for all the input. What I have found is that I must replace only the pulley and pressure disc as the magnetic coil is good. The matching surface on the pulley and disc are badly scored and engage intermittently. I believe this greatly simplifies my repair but will post the final outcome when the job is complete.
