MAINTENANCE AND SERVICING
5.5 Break-In Inspections
Refer to 5.2.1 Break-in Inspections, page 239 for the break-in inspections schedule.
5.5.1 Tightening Drive Wheel Nuts
To tighten the drive wheel nuts, follow these steps.
IMPORTANT:
• To avoid damage to wheel rims and studs, tighten nuts by hand. Threads must be clean and dry, do NOT apply
any lubricant or anti-seize compound. Do NOT use an impact gun, and do NOT overtighten wheel nuts.
• Use only genuine, manufacturer speci fi ed nuts.
1. Torque each nut to 510 N · m (375 ft · lbf) using the
tightening sequence shown at right.
2. Repeat tightening sequence two additional times,
ensuring the speci fi ed torque is achieved each time.
3. Repeat torque procedure every hour until two
consecutive checks con fi rm that there is no movement
of the nuts.

5.5.2 Tightening
At fi rst use or when a wheel is removed, check wheel nut/bolt torque every 15 minutes on the road or 1 hour in the
fi eld until the speci fi ed torque is maintained.
Once speci fi ed torque is maintained, check wheel nut/bolt torque after 10 and 50 hours ( fi eld or road operation), and
then every 200 hour intervals thereafter.
To tighten the on caster wheels, follow these steps:
1. Position wheel assembly on hub and install wheel
bolts (A).
2. Tighten wheel nuts (A) to 163 N · m (120 ft · lbf) using
the tightening sequence shown at right. Repeat the
tightening sequence three times.
