Neu Motor Bearings

[Arct1k]

Help...

I picked up a used Neu 1509 for my slash 4x4 - When I got it the rotor felt really notchy... I could see what looked like some sand on the outer bearing race so I thought I'd open up the motor and have a look...

This was the inside of the bearings...




The question is these are 5 X 13 (15) X 4 flanged bearings...

Do you think I should:

1) Clean up and re-install
2) Buy new bearings - Any ideas where?
3) Send back to Nue for service...

Cheers
