Motor Component Testing and Inspection
Bearing Inspection
NOTE: Replacement of the end cap bearing is highly-recommended if the end cap is removed from the motor. The
following procedure is provided as a guideline for determining general bearing failure.
1. Remove the motor from the vehicle. See Motor Removal on page 20-3.
2. Remove the bearing by performing steps 1 through 14 of Motor Disassembly on page 20-5.
3. Use a clean cloth to wipe the carbon dust off of the bearing. Inspect the bearing by spinning it by hand and
checking for both axial (A) and radial (B) play (Figure 20-14, Page 20-10).
4. Replace the bearing if it is noisy, does not spin smoothly, or has excessive play. Check the bearing and replace if
rusted, worn, cracked, or if there is an abnormal color change in the metal of the bearing.
