1-17. STEERING SYSTEM
STEERING WHEEL. Connected to steering column and steering gear. Steering column and
steering gear control flow of hydraulic oil to and from steering cylinder assem-
blies. Power assist provided by hydraulic pump mounted on transmission for reduced
steering wheel turning effort when engine is running. Collapsible steering wheel
column allows for reduction in height for transport operations by depressing button
in center of steering wheel under cover.
STEERING CYLINDER ASSEMBLIES. Two hydraulic cylinders, one mounted on each side of
loader. Cylinder housings attached to front chassis and cylinder rods attached to
rear chassis. Cylinder rods extend or retract as steering wheel is turned, forcing
front chassis to pivot about chassis spindle assemblies.
CHASSIS SPINDLE ASSEMBLIES. Heavy duty spindles mounted in thrust bearings and lo-
cated at top and bottom of chassis connection points. Secure front chassis to rear
chassis and allow front chassis to pivot and steer loader.
AUXILIARY STEERING MOTOR AND PUMP. Mounted on left side of loader. Provides
emergency hydraulic power for steering loader if hydraulic pump fails. Consists of
hydraulic pump driven by electric motor. Electric motor automatically operates if
main hydraulic pump fails and auxiliary steering warning buzzer sounds when motor
turns on. If you crank starter motor with SHUT OFF control pulled out then release
ignition key switch, you will hear auxiliary steering motor and pump start to
operate. If this happens, turn ignition key switch to off position to stop auxiliary
steering motor and pump.
