Installation

NOTE: Remove all dirt and rust from mating parts
before installing wheel assembly.
1. Using a tire handler, lift wheel into position on
wheel hub. Install wheel retainer lugs (7, Figure
2-1) and lubricated nuts (8). Evenly tighten
each nut using the sequence shown in Figure
2-2 to 300 ft.lbs (407 N.m) torque.
2. Spin the wheel and check rim run-out. Maximum
run-out is 0.20 in. (5mm). If run-out exceeds
specifications, then loosen all the nuts and re-
tighten them evenly as shown in Figure 2-2.
3. If run-out is OK, then tighten each nut using the
sequence in Figure 2-2 to 550 ft. lbs. (746 N.m)
torque.

maintained.
