How is the inside of a rack block machined?
How is the inside of a rack block machined?
The Rack Block is machined in two different ways and serves two purposes. The inside of the Rack Block is machined in a screw-shaped design, just like the Worm Gear. The individual ball bearings roll inside the Rack Block just like on the Worm Gear. The outside of the Rack Block has four straight teeth machined into it.
How does a rack and pinion constraint block work?
A Rack and Pinion Constraint block connects the rack and pinion bodies, eliminating one degree of freedom and effectively coupling the rack and pinion motions. The block imposes special restrictions on the relative positions and orientations of the gear connection frames.
Where is the sector shaft lash adjustment made?
The sector shaft lash adjustment is made after the worm shaft bearing preload adjustment. Turn the adjustment screw in and out of the gearbox’s top plate. Look down over the fender at the top of the steering gear to find the plate. The manufacturer’s procedure will typically center the stub shaft before adjusting the sector shaft.
How does the sector shaft work on a steering wheel?
The Sector Shaft sets down in these needle bearings and serves as the inner race for them. The teeth on the top of the Sector Shaft mesh with the external teeth of the Rack Block. When you turn the steering wheel, you are also turning the Input Shaft and the Worm Gear.

Where does the worm gear and rack block go?
These teeth mesh with the four teeth on the top end of the Sector Shaft. The Worm Gear goes inside the Rack Block and the individual ball bearings fill the grooves cut into both gears. The Rack Block has Ball Guides mounted on it that allow the balls to roll from one end to the other of the grooves cut into the Worm Gear and Rack Block.
