Gears were worn slipped when in use

Screw drivers, Wrench (Adjustable)
I removed the four screws from the gear housing case to view the ring and pinion gears. They were extremely worn and did not engage. I removed the nut locking the pinion onto the armature shaft. Then I removed the 4 screws from the housing and pulled the housing from the body of the grinder. I installed the new gear housing replaced the 4 screws to the grinder . I slid on the new pinion and securely tightened the holding nut. I greased the gears and replaced the gear case lid with the 4 securing screws, Don\'t forget the small rubber seal. Mine was fine so did not replace it just used the old one. I turned the unit on and put it to use. Works better then new.
