If using compressed air for drying
wheel hub components after cleaning, wear eye
protection! Compressed air can cause serious
personal injury if misused. Use compressed air at
safe low levels. NEVER point the nozzle at others.
6. Work fresh grease into the wheel bearings. You can
put the wheel bearing and grease into a plastic zip
lock bag to really work the grease into every small
wheel and bearing.
7. Work fresh grease inside the wheel hub, ensuring
the outer edges are fully covered, and put liberal
amounts of grease onto the axle spindle.
8. Reinsert the wheel bearings ensuring it is oriented
as shown in Figure 5-35, then new seal, washers
and nuts. Continue packing grease inside all the
parts as you install them.
9. Torque nut to 50 ft lbs. Then loosen the nut one
turn.
10. Retighten the nut to 15 ft lbs. To ensure the nut does
not loosen, bend one edge of the washer toward the
outer nut and the other edge side toward the inner
nut. (Figure 5-37)
11. You can spin the hub and rotor to test for noise
and smoothness before reinstalling the wheel and
tire. When packed correctly, the rotor spins freely
without noise.
12. Reinstall tire and wheel. Torque lug nuts. (See
Section 2, Torque Specications)
13. Repeat procedure on the other wheel.

REPLACEMENT PROCEDURES
Batteries
Batteries create explosive gases
when charging. DO NOT expose these gases to
sparks or open ame during maintenance. Always
perform battery service in a well-ventilated area or
outside. Serious injury can occur from exploding
batteries.
When installing batteries, always
install the positive cable rst followed by the
negative cable. Reversed polarity can damage the
electrical system.
1. Remove the black ground (-) cable from the
negative (-) battery terminal, followed by the red (+)
cable from the positive (+) battery terminal. (Figure
