TABLE B PROCEDURES
B-3
Inspect the Tires and Wheels
(including lug nut torque)
Maintaining the tires and wheels in good
condition is essential to safe operation and good
performance. Tire and or wheel failure could result
in a machine tip-over. Component damage may
also result if problems are not discovered and
repaired in a timely fashion.
1 Check the tire surface and sidewalls for cuts,
cracks, punctures and unusual wear.
2 Check each wheel for damage, bends and
cracked welds.
3 Check each lug nut for proper torque.

B-4
Confirm the Proper
Brake Configuration
Proper brake configuration is essential to safe
operation and good machine performance.
Hydraulically-released, spring-applied individual
wheel brakes can appear to operate normally
when they are actually not fully operational.
1 Check each torque hub disconnect cap to be
sure it is in the engaged position.
B-5
Check the Oil Level
in the Torque Hubs
Failure to maintain proper torque hub oil levels
may cause the machine to perform poorly and
continued use may cause component damage.
1 Drive the machine to rotate the hub until the
plugs are located one on top and the other at
90 degrees.
2 Remove the plug located at 90 degrees and
check the oil level.
Result: The oil level should be even with the
bottom of the plug hole.
3 If necessary, remove the top plug and add oil
until the oil level is even with the bottom of the
side plug hole.
4 Apply pipe thread sealant to the plugs, then
install the plugs into the hub.
5 Repeat this procedure for the other torque hub.
