1950 GMC 1/2 ton, stock 228 and 3 speed (column) transmission. Motor and transmission both completely rebuilt, with all new parts, including new clutch, pressure plate, and throw out bearing. I finally got the 3 on the tree shift box hooked up and adjusted on the steering column, so I have been able to take my truck for short rides up and down the dirt road I live on (full frame off resto, been working 5 years on it)! However, when I pulled back into my garage a few nights ago, while the truck was sitting there idling, all the sudden there was a whining noise coming from the flywheel/clutch area. I crawled under the truck while it was running, removed the flywheel dust covers, and think I pin pointed the noise from the new throw out bearing. One thing I noticed while looking up at the bearing, is that it was spinning even while the truck was not in gear. My question is, should the throw out bearing be spinning all the time even while the truck is in neutral? There is room for the bearing to slide back towards the rear (away from the clutch fingers) a little a more, so that it completely disengages the clutch fingers, but when I do that it throws my pedal free play adjustment off. Is the bearing supposed to stay in contact with the clutch fingers (no load though), or should I pull it back? Seems like there may be a fine line between keeping the bearing off the clutch fingers while keeping the pedal free play within specs. Note this a new (long) throw out bearing, that came with the clutch kit. Also note there is a brand new (New departure) pilot bearing in the back of the crank as well. Could this just be a bad/cheap throw out bearing?
