ADJUSTMENTS ON STEERING GEAR INSTALLED IN VEHICLE
Elimination of Steering Play in Straight-ahead Range (Pressure Point Adjustment)
Pull drag link from pitman arm.
Turn steering to center position (found by halving total number of steering wheel turns).
Loosen sealing nut (24) on housing cover.
Turn steering into an end position and measure the required friction torque for turning steering
outside straight ahead driving range (approx. 1/2 turn before final lock). For turning steering,
use a torque measuring instrument which is plugged onto steering wheel nut (55).
Then measure friction torque of steering in pressure point range (center position). For this
purpose, turn torque measuring instrument approx. 1/2 turn each to the left and to the right
beyond the straight-ahead position, while tightening the adjusting screw (62) to the extent that
a friction torque increase of 30 - 60 Ncm as compared with value measured under Step d. is
Tighten sealing nut (24) with a tightening torque of 70 Nm; sealing ring should face housing
cover), while holding adjusting screw in position. Check set friction torque once again. Fasten
drag link again to pitman arm. Adjustment of friction torque in straight-ahead range higher
than 30 - 60 Ncm does not improve the steering characteristics and operating conditions in
steering gear in any way whatsoever. It will actually cause excessive pressure at parts which
are in contact with each other and will thereby result in unnecessary wear.
Adjustment of Steering Limit
For adjustment of steering limit, refer to Section 3, Function and Adjustment of Hydraulic Steering
Limit (Steering Lock).
