Motor Tests

The armature and motor housing are not available as
individual parts. No testing is recommended to deter-
mine the specific area of failure. When a test of the
power wiring system indicates that the system is operat-
ing correctly and the vehicle either does not run or runs
poorly, the motor is the only remaining component and
must be replaced.

Motor Installation

Socket, 7/16", 3/8" drive .............................................. 1
Torque wrench, in. lbs., 3/8" drive ............................... 1
Be sure that a bumper spline is installed between the
motor input pinion shaft and splines. Apply a small
quantity 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-4). Tighten the nuts to 66 in. lbs. (7 Nm) torque.
For TCT motors, install speed sensor to end cover.
