saving an alternator

This thing was doused with salt water a few times during various seawater cooling system failures, and also overheated a lot in the days before I realized that the amp ratings on marine alternators are meaningless. But it was still producing full output when I took it off, and will now become a backup after I rebuild. Other than new bearings, which I already have, what else can be done?

Is there such thing as a spray that will take corrosion off of copper, similar to Ospho for stainless steel?

Anyone know a good source for alternator parts or a good shop who could rebuild? I wouldn't mind doing the work but finding some of the components seems time consuming judging by how long it took me to figure out the bearings. It turns out that using normal bearing sizes would be too easy, the whole starter/alternator industry has their own sizes, not available from normal industrial sources.

I would look for a good local auto electrical rebuilder & take it to them. These things are not rocket science.

Re: saving an alternator

Just find an exchange service and replace it and let them worry about the rebuild.
