MOTOR (MODEL 5BC59JBS6365)

MOTOR COMPONENTS

1. Inspect the insulators (4 and 7) for cracks or other damage (Figure 15a-10, Page 15a-8).
2. Inspect the brushes (13) for damage or excessive wear. Replace brushes if required. See following
NOTE.
3. Inspect the brush springs (14) (Figure 15a-10, Page 15a-8). Replace springs that are discolored from
heat (light gold or blue tinted). Replace springs which apply a force of less than 16 oz. (Figure 15a-8,
Page 15a-7).
CAUTION
• When checking brush spring tension, do not over-extend the spring. Using excessive force
will damage the spring.
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. Refer to Motor Assembly for brush
installation. See Motor Assembly on page 15a-10.
When replacing brushes, replace all four brushes. Never replace only two.
Install the brushes in the same rigging 180° apart from each other.

BEARING INSPECTION

1. Using a clean cloth, 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 15a-9, Page 15a-7).
2. 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. Do
not remove the bearing from the armature shaft unless it is to be replaced.
