7.1 Moving Disabled Truck
Any unusual power train noises noted while
operating the truck should be reported to
those responsible for maintenance. Should
the power train, hydraulic or electrical systems
fail, the machine should be stopped and shut
down immediately until suitable repairs can
be made. If the failure is in the power train
and the truck must be moved to a service
area or workshop to make required repairs,
remove the drive ange covers from the drive
wheels and pull the axle shafts and final
drive planetary sun gears from the planetary
assemblies. This will prevent any possible
additional damage, which may be caused by
the drive wheels turning the power train as the
machine is towed. Replace the covers on the
drive wheels to retain lubricant and prevent
entry of dirt(refer to Fig.7-1).
If possible, start the engine to provide the
required hydraulic pressure for steering and
braking. Never allow riders on a machine
being towed without sufficient hydraulic
pressure for safe steering and braking.
If the nature of the trouble prevents engine
operation, repairs must be made on the site of
the breakdown, or special arrangements made
for towing the machine safely to the repair
area without steering and braking power.
