98 Dodge Ram Clutch Gap Questions

jgcox6 on Mon May 17, 2010 9:11 AM User is offline

Year: 1998
Make: Dodge
Model: RAM
Engine Size: 5.2L
Refrigerant Type: 134
Country of Origin: United States

Hey folks,,,My 98 dodge ram has the classic symptoms of the clutch gap has gotten too big. ( A-C shuts off when the truck gets to operating temp and can tap clutch plate and works fine for awhile). Anyway...got a couple of questions...I am thinking in order to fix it, I will need to pull the clutch plate by removing the nut on the front of the plate..then behind the plate are a couple shims....should I just remove one of the shims? Are they all the same size? I think the gap is suppose to be .016-.031 inch??? Should the feeler gauge be hard to pull out or just snug?

Pull out enough shims to make it so it does not rub when not engaged-- pretty simple logic---shims vary in thickness- you may need to experiment- but I usually hit it on the first try- any thing that creates closer air gap will solve your problem. .020" is a good goal- feeler gage should barely rub both sides when inserted-- that's why it is called a feeler gage...

-------------------------
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......

Just wanted to give the fix to my problem....i did take the AC Clutch off and remove a shim..actually was the only one on the shaft and it brought it within the specs of the ai gap....020...is where it was when I buckled it all up. I just wanted to thank you guys and girls again for you contributing your time and expertise...GREAT JOB!!
