Use tool (D) and fasten a hoist to the hub
assembly and gear. Put the hub assembly and
gear in position on the machine.
Install the nut on the spindle.
Tighten the nut with tool (E) while the wheel is
turned with a 8 in. (203 mm) long lb.in. (N.m)
9S7354 torque wrench. The torque must be 75
+ 25 lb.in. (8.50 + 2.83 N.m). For other lb.in.
torque wrenches, the correct torque indication
can be found with this formula:
A + B
"C" is the torque wrench reading.
"A" is the length of the torque wrench.
"B" is the distance from the center of the wheel to the
"T" is torque on bearings [T = 160 ± 50 lb.in. (18.1 ± 5.7
NOTE: The torque wrench must be
installed on wheel nut so it is in line
with the center of the wheel as
Turn wheel slowly at a constant speed for one or
two turns to check torque reading after
adjustment has been made.
Install lock (7) on the nut. Tighten the nut more
if needed to get the lock in alignment with bolt
holes. Install the bolts and lock wire.
