Steering Gear: Description and Operation

GEAR





DESCRIPTION
The power steering gear is a recirculating ball type gear. The steering gear is securely mounted to the driver's side of the vehicle. The steering linkage is attached to the pitman arm then attached to the idler arm.

OPERATION
The steering gear acts as a rolling thread between the worm shaft and rack piston. The worm shaft is supported by a thrust bearing at the lower end and a bearing assembly at the upper end. When the worm shaft is turned the rack piston moves. The rack piston teeth mesh with the pitman shaft. Turning the worm shaft turns the pitman shaft, which turns the steering linkage.
