Easy DIY repair, note if you remove the armature from the case to grease inner bearing then you need to take the brush covers off that push the brushes against the motor contacts. Easy and simple swap out. Like new now.

Not a plug and play procedure! The replacement part fits several models, but this one had to be modified for the part to work!
1. I attempted to remove the nut. This broke the spindle brake. It\'s bearing broke in the gear case.
2. I removed the guard and narrowed a wrench so I could hold the spindle still. This failed.
3. I removed the front plate from the gear case assy, and removed the spindle.NOTE: it\'s easy to loose the key if the pinion slides

4. Using a vise and 2 pipe wrenches I was able to remove the nut and the remainder of the cutting wheel.
5. I ordered and received the gear case assy. While it was for my type of grinder, it was not identical to the original.
6. I used the bench cut off saw to cut about 3/8\" off the face of the gear case assy where it attaches to the grinder motor. This needed to be done so that the pinion would engage with the ring gear. It would have been much better to do the job with a milling machine.
7. I put the pinion in place, then fastened the gear case assy. to the motor section.
8. I put lube in the gear case assy.
9. Then the front plate and ring gear were put in place. I did this a number of times because the four screws that hold the front in place needed to be shimmed, so the gears meshed smoothly.
10. Replace the guard.

Pay strict attention when disassembling grinder. Clean everything thoroughly. Lay all parts out including broken parts. Take pictures as you go to remind you how you disassembled the grinder. Keep all parts separate from everything else so they don\'t get lost. Back engineer when reassembly. Don\'t forget the grease. Take your time
