The AIM calls the thin head bolt a bolt assembly. should it have a flat or lock washer on it? It didnt look like it took much torque, I wouldn't think it would be a captured lock washer.
Thanks guys
The one that holds the lower sleeve to the rear of the alternator?
Yes. I did read the reason for the thin head was to clear the valve cover. If you add a washer it makes the head stick out too far so I just used the bolt.
Thought I had an original 'takeoff' alternator or 2 that have never had that bracket removed! No washer, lock or otherwise.
