A Word Of Warning: A Loose Gearbox Bolt = Lockup!

Well, my wife had a dash on me TRi yesterday and boom, it suddenly locked up. Thankfully while working on low RPMs.

 

Turned out one of the 5 gearbox fixing bolts vibrated loose and did this:

The little fecker who's fault it all was is in the front in two bits.

 

"Thankfully" it only damaged the crownwheel, if there were high-RPMs the damage could have been way more catastrophic or even engine career-ending:

OSSA doesn't sell it separately, hence you should buy a complete new gearbox. Thankfully Joa has found me a s/h one that they can hopefully replace the clutch basket crownwheel with.

 

Be sure to locktite those gearbox fixing bolts! Do not overdo them as well (you may stip the thread or they weaken). Just right amount of torque and locktite.
