TIRES/WHEELS/LUG NUTS
Tires and wheels are very important and critical components
of the buggy. When specifying or replacing the wheels, it
is important that the wheels, tires, and axle are properly
matched.
TIRE WEAR
The tires (Figure 24) used on the power buggy are
pnuematic. Proper inflation is 28 PSI (193 kPa). In addition,
inspect the tires for cuts, wear and deformity.
Figure 24. Tire Inspection
LUG NUT TORQUE REQUIREMENTS
It is extremely important to apply and maintain proper wheel
mounting torque on the TuffTruk. Be sure to use only the
fasteners matched to the cone angle of the wheel. Proper
procedure for attachment of the wheels is as follows:
1. Start all wheel lug nuts by hand.
2. Torque all lug nuts (Figure 25) in sequence.
DO NOT
torque the wheel lug nuts all the way down. Tighten
each lug nut in 3 separate passes as defined by Table 6.
CAUTION
DO NOT
attempt to repair or modify a wheel. If the rim
is cracked, replace the rim immediately and inspect the
tire for cuts, wear, and deformations.
