LUBRICATE BALLS, AFTER ASSEMBLY, WITH LIGHT OIL.
Minimum Backlash of Typical Studs in Cam Groove.
Adjust so that a very slight drag is felt through the mid-position when turning he steering wheel slowly from one extreme
position to the other. Backlash of tuds in the groove shows up as backlash at steering wheel and at ball on steering arm.
The groove is purposely cut shallower, therefore narrower, in the mid-position ange of travel of each stud (see illustration)
to provide close adjustment where usually the straight ahead driving action takes place. It also makes this close
adjustment possible after normal wear occurs.
Therefore, adjust through the mid-position. Do not adjust in position off mid-position as backlash at these points is normal
and not objectionable.
To adjust, tighten side cover adjusting screw (10) until adjustment is correct and tighten the locknut (9) to hold it. Then give
the gear a final test.
Secure the gear at all points loosened prior to making the adjustment. Also check tightness of mounting bracket bolts and
nutes, and of steering arm on lever shaft and the nut lockwasher. With all support brackets clamped tight, turn steering
wheel to see if any binding exist. If so, the column is probably out of alignment and need correcting. (Refer to Column
