How to remove clutch from 2004 avalanche

jgcox6 on Tue July 12, 2011 4:34 PM User is offline

Year: 2004
Make: chevy
Model: avalanche
Country of Origin: United States

I have a friend that has a chevy avalanche that the clutch keeps disengaging...we have tried closing the gap...and that worked for a few it is doing it again. One of the suggestions was to remove a shim...these don't have shims do they? If not are we left replacing the clutch? If so how do we remove the clutch and replace it? Please advise asap..its hot as crap in Memphis...Elvis is even sweating!

How did you "close the gap" before then? That looks like the type that has shims. The old GM compressors had a press on plate (adjusted by pressing or pulling with a special tool) but this seems to be a Japanese style compressor. Remove the nut or bolt in the center (on the compressor shaft) and the plate should come off.

I was told originally that I could use the compressor remove/install kit. I actually seemed to close the gap by using it...but I have to bow to your expertise on these things. If you say that it is a matter of removing the nut and remove a shim then we will try that. please let me know for sure

A nippondenso pump requires nut removed (impact tool) and carefully remove clutch- count shims that drop out and remove thickest one. Uusally happens on high mileage vehicles-- 150k or more.............

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......
