It's been a while, but I believe that's correct. Use a drift to drive the fwd end of the pin. A little heat on the casting won't hurt.

The springs that hold the brushes against the commutator are carbon steel and will corrode - faster if the starter has had a dose of bilge water in the past. If you have access, you can pull the...

I think it more likely that the alternator failed due to corrosion of one or both slip rings, preventing current from getting to the rotor. Not a big deal to crack it open and clean the rings....
