Align the commutator end cover with the holes in the
motor housing and assemble (Ref Fig. 3 on page G-2).
Secure the commutator end cover to the motor housing
with bolts (2) and tighten to 90 in. lbs. (10 Nm) torque.
Install bearing cap (1).
Motor Tests
The field coil and motor housing are not available as indi-
vidual parts. 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.

Be sure that a bumper spline is installed between the
motor input pinion shaft and splines. Apply a small quan-

install the mounting hardware. Tighten to 168 in. lbs. (19
Nm) torque (Ref Fig. 2 on page G-1).
Attach the four motor wires to motor (Ref Fig. 6 on page
