What do you guys normally replace when rebuilding an generator or does everyone just use a alternator? I've taken apart 3 rusty, mud dauber filled generators. They are all 2 brush type, one with a ground terminal and 2 without. The only other difference I can find is that the front bearing is larger on one than on the other 2. I hope to get at least one good 12v generator out this stuff. Bought an early 60's regulator from Autozone and 12v field coils and brushes from C&G. I thought I was also getting a modern sealed front bearing, but it turned out to be an original style. This looks like a good place for a sealed bearing, since there seems to be no way to lubricate the front bearing. What do the rest of you do when rebuilding one of these? The armatures are pretty weathered. Is there a way to test them when apart? I know it is easier to put an alternator in, but I'd like to stick with the generator. After my recent experience with a local shop screwing up the Lucas generator for my Allard, I decided to tackle this project myself.
