My mysterious 2001 Boss Hoss ZZ4 crankshaft to alternator belt problems appear to have been resolved.
Original symptoms:
- Chattering
- Squealing
- Belt coming out of the pulley groove
- Belt snapping
These symptoms were frequent. Sometimes, I'd end up changing the belt twice in the same week. I always carried a spare, as I'd ended up doing a roadside change, a time or two.
Root cause:
Loose crankshaft pulley (not obvious by observing it in motion); slightly out of tolerance, just enough to cause problems
I do not yet have an harmonic balancer and alternator pulley spacer, so for now, the factory configuration is tightened back down with a little help from Loctite.
The alternator pulley is fine and so are the mounting brackets, so no issue there.
