REPAIR OF CARRIER STEERING SYSTEM
REPAIR OF STEERING WHEEL, COLUMN AND GEAR BOX
The carrier is equipped with a mechanical steering
system with hydraulic power assist. The carrier steer-
ing system incorporates three methods of steering; (1)
two-wheel steering, (2) four-wheel steering and (3) crab
steering. The operator selects the steering method most
desirable, for specific operating conditions, with a
selector valve in the carrier cab. In two-wheel steer, the
rear wheels are locked in the center position by a lock-
ing pin, and steering is accomplished with front wheels
only. In four-wheel and crab steer both front and rear
wheels are utilized in steering. In four-wheel steer, the
rear wheels rotate opposite of the front wheels to
reduce the turning radius. In crab steer the rear wheels
turn in the same direction as the front wheels, allowing
the vehicle to move in a crab-like fashion.
