This section has the description and repair procedures for the steering housing and the steering control unit.
Additional information on parts of the steering system can be found in the Steering Axle and Hydraulic
System service manual sections for your lift truck.
The steering column assembly uses a steering con-
trol unit with hose connections on the bottom of the
unit. The steering housing has mounts for the steer-

steering linkage to move the steer tires. Hydraulic
