Decided this morning to replace the bearings in the Olympia.
Took the motor apart.
The back bearing seems fine.
Drilled out the rivets that hold the front bearing cap in place.
The front bearing needed to be replaced.
The old bearing was corroded in place.
Got it out, cleaned up the opening, put the new bearing in place then used screws with lock washers and nuts to put it back together.
Since it was apart I cleaned the fans.
Assembled everything back together.
Before I put the motor back in the body I cleaned up the commutator.
All back together and runs a lot quieter.
