5.6 Break-In Inspection Procedures

For the break-in schedule, refer to

5.6.1 Tightening Drive Wheel Nuts

At first use or when a wheel is removed, check wheel nut/bolt torque every 15 minutes on the road or 1 hour in the field
until the specified torque is maintained. Once specified torque is maintained, check wheel nut/bolt torque after 10 and 50
hours (field or road operation), and then every 200 hour intervals thereafter.
To tighten the drive wheel nuts, follow these steps:
IMPORTANT:
• To avoid damage to wheel rims and studs, tighten the 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-specified nuts.
1. Locate drive wheels (A).
2. Torque each nut (A) to 510 Nm (375 lbf·ft) using the
tightening sequence shown at right.
3. Repeat the tightening sequence two additional times,
ensuring the specified torque is achieved each time.
4. Repeat the torque procedure every hour until two
consecutive checks confirm that there is no movement of
nuts (A).
