Steering Gear: Description and Operation
DESCRIPTION
The power steering gear is a variable ratio recirculating ball type gear. The ratio is 15:1 on center, reducing to 13:1 at the end of travel.
OPERATION
The 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.
CAUTION: Components attached with a nut and coffer pin must be torqued to specification. Then if the slot in the nut does not line up with the
coffer pin hole, tighten nut until it is aligned. Never loosen the nut to align the cotter pin hole.
