We thought it might have been the belts, but we changed both of them and tightened the alternator. But is this noise coming from the clutch? And if so, what could be the issue?
Engine is a Detroit 6-71 and the tranny is a Spicer 5-speed.
Thanks for any help
Cheers,
Grizz

Throwout bearings can squeal during a shift if you use the clutch. I would put the clutch down lower on the suspect list. How wide are your belts. If they are too narrow, they will squeal on acceleration and when you over run the governor. | | |
