MOTOR ASSEMBLY
See General Warning, Section 10, Page 10-1.
1. Replace the bearing.
1.1. Use an arbor press to install a new bearing into the end cap. To help avoid damaging the bearing,
apply pressure only to the outer race when installing the bearing.
1.2. Install the retaining ring to secure the bearing.
2. Install the brushes and brush rigging. See following NOTE.
NOTE: When installing new brushes, remove and replace brushes one at a time. This method ensures the
terminals and brushes will be properly positioned in the rigging.
When replacing brushes, replace all eight brushes.
Install the brushes in the same rigging 180° apart from each other.
2.1. Insert the brushes into the brush rigging as shown.
2.2. Insert the two terminal posts through insulators in the end cap (20) wall at the A1 and A2 positions
(Figure 16-13, Page 16-10) .
2.3. Place external insulators and washers on each terminal post, and secure terminal with nuts.
Tighten nuts to 100 in-lb (11.3 N·m). Ensure that the terminal posts do not rotate when tightening
the nuts.
2.4. Secure the brush rigging to the end cap with four bolts. Tighten the bolts to 25 in-lb (2.8 N·m).
