One brush is almost at the wire so it needs replaced. The armature has some groves but the lathe can take of that. Where you find the brushes??Your brushes and armature are probably fine. Just clean them up. Even wear is normal.
The seal can be found at any seal/bearing house such as Purvis Industries.
I just reworked my electric motor after it failed. Works great:thumb:
Looking at doing this and was wondering if I could just delete the factory filter and housing since it has less filtration than the cat filter?
You can delete, but why? when more filtering is better
stock filter is 8 micron, CAT or Airdog is 2 micron, by the time it goes through a 2 micron filter, the 8 micron filter has nothing to filter..delete the stock junk and run an AirDog or Cat filter
