Removal, Installation, Follow-On Tasks
WARNING
•
Floor jack, if used, must be positioned directly under axle to prevent slippage. Floor jack must be
used only on a hard, level surface to prevent shifting of semitrailer. Direct all personnel to stay
clear of semitrailer when supported in the air. Failure to comply may result in injury or death to
personnel or damage to equipment.
•
Tire and wheel assembly weighs 179 lb (81 kg). Use two personnel to handle tire and wheel
assembly. Failure to comply may result in injury to personnel.
•
For service and repair tasks on the semitrailer, the ground boards and tire chocks should be used to
ensure safe coupling and prevent semitrailer movement. Failure to comply may result in injury or
death to personnel.
NOTE
•
Replacement in the form of tire and wheel assembly changing is also an operator task. Refer to
WP 0022 to remove the spare tire and wheel assembly from the carrier.
•
If floor jack and jack stands are not available, use basic issue 12-ton (10.9-metric-ton) jack.
•
There are eight tire and wheel assemblies and they are all replaced the same way. This procedure
covers one tire and wheel assembly.
