Hi All
I have successfully rebuilt my AC compressor and thought I'd post up the part numbers for others.
The vehicle is a 2005 Envoy XL with the 4.2 engine.
I did some cross referencing and side checking and took a chance on the Santech shaft seal and gasket set. I wasn't 100% sure but it's in the vehicle working so now I can pass the info along.
Shaft seal MT2158 $17.99
Gasket Set MT2207 $4.59
Purchased both from Autozone, $30.65 with shipping and taxes, a lot cheaper than a rebuilt.
There was nothing wrong with my compressor except that the shaft seal had worn out and the refrigerant had leaked out. You need to disassemble it and your space needs to be clean. After reassembly I added oil to the compressor and reinstalled it with new line seals all around as well. I also replaced the orifice tube and the receiver dryer and added oil to the new receiver dryer. Four cans of 134a went in yesterday (48 ounces) and it's running perfectly, it sits right in zone A of the chart in the service manual and the pressures are all within spec.
I hope this helps someone else avoid spending hundreds for a rebuilt.
