Rotor Bearings and Seals

The inner race is attached to the bearing assy.
-The outter race, replace if the surface is pitted or not smooth.
-Flip rotor over and you should feel the two "D" cut areas where you can drive (tap) a brass punch and catch the race to pop it out the rear.
- Tap in the new outter race the way the old one came out. Tapping w brass punch, around evenly until its full seated. You will know its fully seated when the hammer gives a solid "kick back".
Good luck.
