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 vehicle 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, it is advisable to carry out the following procedures to prevent any
possible additional damage, which may be caused by the wheels turning the
power train as the vehicle is driven or towed.
If the transmission is at fault, disconnect the drivelines to the axles and engine
before moving the vehicle.
If a differential or planetary is at fault, carry out the following procedure for the
component concerned: Disconnect drivelines, remove planetary covers and
remove the axle shafts. Remove the pinion gears from their covers. Replace the
planetary pins in the covers, and refit the planetary covers on the drive wheels to
retain lubricant and prevent ingress of dirt.
If possible, start the engine to provide the required hydraulic pressure for
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 vehicle safely to the repair area without braking and steering
power.
Note: Never allow riders on a vehicle being towed without sufficient hydraulic
pressure for safe braking.
If the parking brake must be released, but the engine cannot be operated to
provide the required hydraulic pressure, the brake can be released manually by
following this procedure:
WARNINGS
Disconnecting transmission
from engine will prevent the
steering pump from operating,
making the vehicle difficult to
steer.
Removing the driveline
between the parking brake and
the rear axles or removing the
axle shafts and planetary covers
or pinion gears from the axles
will make the parking brake
ineffective.
Uncontrolled vehicle
movement hazard. There is no
mechanical connection between
the vehicle wheels and the
engine when the parking brake
is released. Before releasing the
parking brake, make sure the
vehicle wheels are secured with
chock blocks to prevent or
restrict unexpected vehicle
movement.
