Carbon Brush Set CB325

Opened rear casing of unit to expose brush holders on each side. Lifted spring that holds each brush and pulled out worn brush and replaced with new brush. Repeat for other side.

1. Noted position of all components as per the schematic provided on website.
2. Disassemble all screws to remove cover and output gear assembly.
3. With needle nose pliers carefully remove carbon brush set slip on connector. Place pressure spring to one side allowing removal of brush.
4. Pull armature out. If rubber retaining gasket remains in unit and doesn't come out with the armature and attached to the bearing, take a gasket hook removal tool and remove the grommet being careful not to damage it.
5. Place the grommet on the end bearing.
6. Insert the armature assembly with grommet into the grinder body placing the grommet into the socket inside the grinder body.
7. Attached carbon bushings into their respective positions.

Open housing and disconnected the wires, then installed the new brushes.

Removed the rear cover and disconnected the old brushes and replaced the old ones. Easy job

Remove the back cover and replace the brushes.

Remove rear cover. Remove the brush holder by removing the screw that holds it in. Remove brush by disconnecting terminal. Insert the new brush holder in the same place of the old one. Place new brushes in the holder and release spring to hold brush in. Reconnect the new brush terminal. Then place the rear cover back on.

Basically I did a test with the multimeter and then I did another with a tool called growler, I picked up the problem.
