I will probably need to replace my C182's alternator (again) in the near future - does anyone have any experience of the available brands?
Why replace when it can be overhauled?

This is my second alternator in less than three years, last time the casing came apart! I am trying to discuss the fault with the US manufacturer, but so far it is a one way conversation.
PS I should add that Adams supplied the alternator (it isn't a Plane Power model), sorted it out the problem last time without delay, and have offered to get it sorted this time. I may still take them up on their offer, but would like to discuss the issue with the manufacturer first.

The looseness of the case is a mechanical issue on all the Ford style alternators. The way the housings are fitted to the stator allows for movement after the alternator is heated up and run with a load, something which we cannot duplicate in production testing. This is why you found the housing bolts loose but still safety wired. We currently affix a decal to the housing and recommend the through bolts be re-torqued after the 1st 10 hours of operation and then each 100 hours thereafter. It’s been my experience the 1st 10 hour re-torque and the 1st 100 hour inspection will be all that’s needed.
