Strange Noise

[Phil Waterman]

Hi Stewart

Charlie Fitton may have hit the problem right on the nose with the pilot bearing several different types used from roller to bronze bushings which can and do make noise. What condition is the bearing surface on the transmission piloted shaft?

From your posting it is unclear if the noise goes away when the truck is in gear and moving?
Also when the clutch is pushed in is it trying to spin the transmission?
Is the sound the same with the truck transmission in gear with the clutch disengaged as it is when the truck transmission is in neutral? Reason for these questions is to rule out a miss alignment of the transmission to the engine. When you did the engine swap did you check the centering of the crankshaft to the mounting hole for the transmission (see manual for details). I had to replace a broken bell housing and was surprised how much out of alignment the new bell housing was.

Also does the noise change between the point where the clutch has just released and all the down on the peddle? If so check peddle adjustment to see if the clutch is being pushed two far in.

Is there any indication of clutch slippage?
