END OF TASK
REMOVAL
WARNING
The use of Personal Protective Equipment (PPE) is required when using or handling hazardous
materials associated with operating and maintaining equipment (jet fuel, hydraulic luid, brake
luid, ethylene glycol, cleaning solvents, compressed air, and engine/axle oil). Failure to use
PPE when handling these materials could result in injury or death.
CAUTION
Axles are itted with brake controlled back offs to maintain constant clearance of (0.02 in) within
the brake pack. It is important that only one side at a time is dismantled to prevent damage to
the bearings and to preserve the crown wheel and pinion backlash settings.
NOTE
When changing friction plates, change all plates, do not mix new and old plates on the axle. To
ensure long brake plate life, ensure oil is changed at proper intervals to ensure worn friction
material does not damage seals.
If old plates are reused, note orientation of brake friction plates during removal and reinstall in
the same order.
