end of the crank was a needle roller style bearing . These are normally a bush , I
thought .
Never mind , I cleaned the rust off it and lubed it , polished the tip of the g/box input
shaft and fitted it all back up.
Now , as I drive down the road , at maybe 30 or 40 mph , I hear a light tinkling sound
from the clutch region .
I'm guessing that the lubed bearing is now loose and floating about a bit .
What are the implications ,if that guess is correct ? :confused: | | |

The crank, flywheel, clutch, and tranny input shaft are all in lockstep when the clutch is engaged. Pilot bushings and clutches usually make racket when you push the clutch pedal in. It might be the TO bearing, linkage, fork, or tranny input bearing. Notice any wobble in the input shaft when you had it out? Or maybe its just the tranny bolts falling out of the bellhousing. Some trucks just need to tinkle.  chip

1. The needles in the needle bearing fell out and are rattling around and about the flywheel.
2. The springs in the clutch plate are are a little loose and arerattling. (One could also be broken)
3. The throughout bearing is slightly touching the fingers on the presure plate and are tinging.
You shoud be able to see some of these by removing the flywheel cover and checking them out.
I hope this helps.
