WARNING
Explosion hazard!
Never weld on a wheel. Welding can cause stresses that will cause a wheel to crack or break unexpect-
edly. Tires can separate explosively during welding. Always have a qualified tire mechanic service
wheels and tires.
Failure to comply could result in death or serious injury.

Tire or rim service
Always have a qualified tire technician service the tires
and rims for this machine. It is recommended that you
have this technician inflate the tires. To prevent acci-
dents, use a restraining device (tire inflation cage), cor-
rect equipment, and correct procedure.
Explosive separation of the tire (single piece rim), or the
tire and/or rim parts (multi-piece rim) can cause serious
injury or death.
Stud mounted wheels (if equipped)
Machines equipped with optional heavy duty axles have
a stud mounted wheel. The Heavy Duty (HD) axle in-
corporates a stud and nut assembly.
Wheel bolt torque
If necessary, tighten the wheel nuts to the required
torque.
Use a hand wrench (not an impact) to tighten the wheel
bolts to pull the wheel against the planetary housing.
Tighten the wheel bolts using the sequence shown.
First tighten the bolts to
278 N·m
(
205.0 lb ft
), then
tighten to a final torque of
640 – 720 N·m
(
472.0 –
531.0 lb ft
), using the same sequence.
