PASSENGER CAR MODELS
CONSTRUCTION
The steering gear used in the
passenger cars is of the roller sector type with an hour glass worm. The
sector roller rotates on a double row
of ball bearings, Fig. 1.
The gear ratio is 17.5 to 1. |
The sector
shaft rotates in two long bushings having oil grooves for adequate
lubrication. The upper worm
roller bearing is mounted in the adjusting sleeve, assuring accurate
alignment. The wormshaft is aligned at the top by a spring-loaded
ball bearing mast jacket
bearing.
A
slit-spring seat in the ball bearing serves as the lower spring seat, while the upper
spring seat is the machined
shoulder on the core of the steering wheel.
ADJUSTMENTS IN CAR
All steering gear to frame
mounting bolts should be tightened and
the pitman arm removed before any adjustments are made.
To Remove Wormshaft End-Play
1. Loosen
the mast jacket clamp bolt "B" at the housing. Fig.
