I have to agree with the guys above. With half of the hard work done (getting it disassembled) I believe I would spend the bucks on a Pressure Plate, Clutch, and Throwout Bearing. Theory is that will keep you from doing this same exercise again in a few months or a year.
Resurfacing the flywheel... I have done it both ways. I have slapped a new disc into an old pressure plate and against an unsurfaced flywheel before. They NEVER last as long that way. Often times the clutch will "chatter" and not engage smoothly.
Throwout bearing... I have put them back. They spun good. They appeared free. Get a little bit of old dust or dirt on it and it squeals and makes driving your truck into a miserable experience. That bearing is the cheapest part of the bunch. I personally wouldn't put the old one back (ever). That is
ever again in my particular case!
I do have a bigger question for you though: You mention "
put the transmission back in my truck after 10 or 15 years". Is that because you lost interest in the project for a while or it took time to find new parts - or maybe "Life Happened" between when you disassembled the truck and now? Might be none of our business, but even for old slow me, ten years is a long time.
