Alternator Pivot Bolt
« on: December 09, 2019, 18:00:58 »
Usual can of worms as I start to tear down the car and find lots of things done wrong...

Does anyone have the correct sizing of the Alternator Pivot Bolt - Mine is too small and causing lots of vibration as it can wobble on the mount...

I'm thinking it would be 8 mm but maybe someone knows for sure.

Dan is correct, it is a M8 (8mm) bolt 100mm long

Thanks all. Bought calipers to verify. Either I have the wrong bolt or aftermarket alternator
