MOTOR
Read all of Section B and this section before attempting any procedure. Pay particular attention to Notices, Cautions, Warnings and Dangers.
Align the commutator end cover with the holes in the
motor housing and assemble (Ref. Fig. 3). Secure the
commutator end cover to the motor housing with bolts
(2) and tighten to 90 in. lbs. (10 Nm) torque. Attach ring
magnet to armature shaft with screw. Install inner snap
ring in cover and insert speed sensor. Secure with sec-
ond snap ring (Ref. Fig. 3).
Motor Tests
The motor housing is not available as an individual part.
No testing is recommended to determine the specific
area of failure. When a test of the power wiring system
indicates that the system is operating correctly and the
vehicle either does not run or runs poorly, the motor is
the only remaining component and must be replaced.
