Hi All
Anybody had one of these let go before. It ate my alternator.

Looks like its fractured just along the extent of the high temperature from the mig welding? Wonder who/ where that was made? Presume its a pattern part!

I wonder if it had a crack in the metal?

I've had several fail here...I put it down to either the chain being worn our (they always seem to fail when the chain it old) or the nut clamping the adjuster is not tight enough and the shoe moves and the pivot doesn't.

as Mark Cook advices, I do run mine witouth it.
spending a new chain every 10 000 ore 15 000 km's is the better and easier way to go, IMO.

Interesting that people run without a tensioner. Has anyone got any bad experiences of this? My chain is new. Did I get away lightly with just the alternator?
Thanks for all the help everyone.

I recall an ancient thread on this.....anyone?

A new chain hardly needs a tensioner, I wonder how it trashed the stator?
