Clutch Installation
This was a necessary evil. Being that the motor was taken out and the trans off, I may as well include a new clutch in the rebuild. It makes sense, but wasn't cheap. Looking at the old clutch, I could easily tell it was finished. The pressure plate tines were so worn that some were broken off. The throwout bearing was dried out and the clutch plate was worn almost completely through. While I was at it I removed the flywheel and had it resurface. I took the fylwheel to a fleet truck repair place (Truck Fleet Repair in Norfolk, VA had excellent customer service!). They had a machine large enough for the bigger flywheel . My pilot bearing in the flywheel was probably original. It was a cage style bearing and was broken. I had them replace that with a sealed newer style bearing. I got everything back together and it feels good but the hit my wallet took wasn't fun, on top of the trans rebuild, adapter parts etc.Here's a pic of the new clutch.Pic of the old busted bearing:Lessons Learned
- Big flywheels need big machines, heavy lifting.
- The clutch is a GM style big block clutch that came in many many GM vehicles. I used 1988 GMC Suburban with the 6.2 Diesel. This should work for you. Keep you're old one for comparison if you have it.
- I didn't need the provided pilot bushing for my application.
- Flywheel to crank bolt torque specs are 101ft lbs.
- Clutch pressure plate to flywheel bolt torque specs are 12-15 ft lbs.
