8. Pull straight out to remove from wheel hub.
NOTE: If the wheel motor is to be removed from the
truck for service, install approximately 8 flanged nuts
with appropriate spacers in place of the outer wheel
adaptor ring and nuts removed in step 4. This will
provide additional support for the wheel motor trans-
mission (12) during removal and transportation.
Installation
Always keep personnel away from a wheel assem-
bly when it is being removed and installed.
NOTE: Clean all mating surfaces and check stud
threads before installing wheel assemblies.

with lithium base grease. Install and tighten nuts
in the following sequence:
a. Install six (6) nuts at the 12 O'clock and six (6)
nuts at the 6 O'clock positions. Tighten each
nut to 1715 ±100 ft. lbs. (2326 ±136 N.m)
torque.
b. Install three (3) nuts directly below the 3
O'clock and three (3) nuts directly above the 9
O'clock positions. Tighten these nuts to 1715
±100 ft. lbs. (2326 ±136 N.m) torque.
c. Install three (3) nuts directly above the 3
O'clock and three (3) nuts directly below the 9
O'clock positions. Tighten these nuts to 1715
±100 ft. lbs. (2326 ±136 N.m) torque.
d. Install the remaining nuts and torque in a
clockwise direction to 1715 ±100 ft. lbs. (2326
±136 N.m) torque.
e. Retorque all nuts in a clockwise direction to the
required 1715 ±100 ft. lbs. (2326 ±136 N.m)
torque.
