Brush Installation

NOTE: Install brush with wires on same side of motor as

before. Plug spade terminal into connector.

1. Install new brush (B) so lead (L) is in long slot (D) of

holder.

2. Slide terminal (L) under terminal screw (R). Make

sure motor lead terminal (T) is still connected at

screw. Tighten screw.

3. Install spring (S) so it will uncoil onto brush (B), as

shown. Spring will be damaged if installed

backwards.

4. Install spring clip (C) and push in until hooks (H)

catch slots in housing. Incorrect installation may jam

clip.

5. Reinstall brush inspection covers, gaskets, and

screws. Reinstall motor cover, screws, washers,

and drive housing/pump assemblies.

6. Test brushes with both pump pins (F) disconnected,

page 32.

Select J 1 (jog mode). Press motor to start

motor. Slowly increase jog setting to J 6. Inspect

brush and commutator contact area for excessive

arcing. Arcs should not “trail” or circle around

commutator surface.

Run motor for 20-30 min at J 6 to seat brushes.

CAUTION

When installing brushes, follow steps carefully.

Improper installation damages parts beyond use.
