  • Ball bearings minimize friction between rotating parts in your tool. The balls or rollers bear the load and spin, distributing the weight evenly, while the minimal contact area of the balls reduces friction. This reduces wear on the tool, allowing it to run smoothly.
    rn
  • Bearings experience constant wear when the tool is in operation from pressure, heat, vibration and friction. Because of this, many Bearings need periodic maintenance or replacement.

    Either it was the wrong size or there were multiple bearings as this one was smaller than the one I could see so I left the old one in there.
    Replacing the shoe base wasn’t too difficult but the trick is to remove the licking arm the holds the adjusting nut in place. It is done easily with a Phillips screwdriver but it is not obvious that it needs to be removed first.

    Tool Type:
    Grinder
    Parts Used:
    Ball Bearing - 211031-6
    Carbon Brush Set - CB303
    Repair Difficulty:
    Medium
    Time Spent Repairing:
    15-30 minutes
    Tools Used:
    Screwdriver, small vise, spray cleaner and small piece of 600grit paper
    rear commutator bearing wore out and brushes wore unevenly loosing power
    1. Took apart black and decker 9 amp grinder.. took pics with phone for trigger button and hold down pin. Also taking notes of length screws and where.
    2. Gently separated handle (2 pieces). Took more pics. Analysed damage. Removed brushes by removing black flat caps, lifted torsional spring and lifter them out. Also spray cleaned the insides and all vents wiping everything clean from grit and whatever that black stuff is..
    3. Slid out motor, brake cleaned off dust and grim. 600 grit sand paper on brush area very lightly to clean. Removed old bearing with vise by gently twisting it off.
    4. Added the rubber ribbed boot then bearing on motor assembly.
    5. Slid motor assembly back in making sure bearing-boot assembly was completely inside its support.
    6. Raised each torsional spring sliding the brush in with wire facing the slotted end to float freely. Then let the spring down on top of the brush.. then the black plastic protective cap on the brush assembly.
    7. The trigger lever and locking button was tricky. The black push lock button goes in one of 2 ways. Most I would imagine would be similar such that placing it in the handle first, it should point strain up in alignment with trigger. The trigger fits in the one side with the black push button..which needs to be put in its place before securing it fully it on the motor assembly. Make sure the black plastic cap did not fall off in the process as it can (and dislodge preventing the 2 halves coming together tightly..do not force..it should slowly come together with gentle persuasion).
    8. Making sure no wires where hanging loose and in their proper places and clearance slots.. move trigger switch into position into the handle half you have with the trigger.. Holding switch in place, check trigger operation for the on off clicking, then the black lock button that holds the trigger on-in..
    9. Gently lower top half on..making sure the trigger pin pivot fits inside that half properly and with the switch still in its position. Also double checking no wires came loose and may be hanging outside the interior and may get caught up in the 2 halves coming together.
    10. Screw back together and check trigger operation again. Pat yourself on your back..
    11. Optional. Check grinder head pinion gear bearing.. Mine was good, I scrapped off the old grease and added high speed bearing gear grease to the pinion and crown gears in the head of the grinder..(4 screws from the top)..
    12. Testing. It will take a few minutes for the brushes to set properly imo. Also, until the bearing grease in the head moves a bit, there will be a lot of drag. It goes away after a few seconds or so. fresh everthing. Grinder worked like brand new! Thanks eReplacementparts.com!!

Then put in new brushes and close the tool up..
