Power Steering Gears - SAGINAW Ball Bearing Worm & Nut: Description

Saginaw manual steering gear is of the recirculating ball worm and nut type with steering shaft, worm shaft and ball nut all in line. The ball nut, mounted on worm, is driven by ball bearings which circulate in spiral grooves in both worm and ball nut as a rolling thread. Ball return guides, attached to nut, serve to recirculate both sets of balls. The ball nut is one piece and geared to sector shaft. Teeth on ball nut and sector are designed so a tighter fit exists between teeth when wheels are straight ahead. Worm shaft bearing adjuster is used to provide proper bearing preload on worm shaft. Sector gear lash is set by adjusting screw on end of sector shaft.
