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-
tity of molybdenum grease to the male portion of the
spline. Carefully mate the motor spline with the input
shaft of the rear axle. Align the orientation marks and
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
G-3). Tighten the nuts to 66 in. lbs. (7 Nm) torque.
