Hmmm=E2=80=A6..mechanical noise?
Two things come to my mind:
1. A flywheel bolt is touching the clutch plate?
2. Too much leash in the drive train? Gearbox, prop shaft, diff?
Cheers

It sounds like a heck of a shock load to break a gear, hard to believe =
that it's a friction surface issue, sounds more mechanical.

Subject: [Fot] Its Opinion Tyme Again...
OK, so I've had a weird problem with the clutch on The Duke of Oil =
(TR4A). It suddenly started acting like an off/on switch with no chance =
of slippage to get goin. The engagement was so sudden that it broke a =
side gear in the locker. Upon review everything appeared well within =
spec. I changed the clutch disc. transmission input shaft and changed =
the throwout bearing sleeve. No dice...same issue.
Got it apart again and have changed everything...disc, pressure plate, =
bearing, crankshaft bush, cross shaft bushings, clutch hose, clutch =
slave cylinder and clutch master cylinder...pedal assembly seems smooth =
without any binding. Have also double pinned the throwout fork to the =
cross shaft.
=20
SO...any thoughts?
=20
Also have pinned the throwout bearing flange so that it will not spin on =
the sleeve. Anybody else pin the flange, or do you let it turn on the =
sleeve? Why/why not?

Broken gears and tears in NorCal
