Steering Gear - Power: Description

TRW and Saginaw power rack and pinion steering units are both used. Power assisted rack and pinion steering gear is mounted on front frame crossmember behind left axle. Rotary turning motion of steering shaft is converted to transverse movement of rack through meshing of pinion and rack teeth.

A rotary valve in pinion assembly directs fluid to either side of integral rack piston which is permanently secured to rack. Tie rods and tie rod ends transmit movement to steering arms and wheels while at the same time accommodating suspension movement. In the event of drive belt or pump failure, manual steering control is accomplished through drive tangs on pinion which are loosely mated with stub shaft. (Steering effort will be increased).
