Compressor reseal

SmokeandMirrorsTrick on Sat August 27, 2011 9:16 AM User is offlineView users profile

I was wondering if Theres a special tool or a trick of so sort to separate the compressor housings. Its a v5 off of a sunfire. I'm replacing the o rings and shaft seal. I took a junk one apart one time just for Shits and giggles and separating the housing was a mother f******. I'm sure some of you have done this quite a few times, anything to make it easier would be great. Thanks

I put the front head ear in a vice and use a "chain vice" to hold on to rear head- and gently rotate back and forth a few degrees until it works apart-- likewise on the cylinder to front head. Do not rock the rear head more than about 3 degrees, you will move the valve plate retainers on the disharge reeds on the rear valve plate--been there, done that.

Yeah some can make you sweat.....

If you don't care about the shaft-- then you can pound it apart with a 10 lb hammer.

The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
