Checking Straight-ahead Position of Steering and Vehicle
Check up steering axles (if the vehicle has no rigid steering axles, place wheels on rotary supports).
Move steering gear into center position by having the total steering wheel turned. Then continue
turning the steering wheel until the marking notches on steering spindle and end flange, or on
angular gear version and angular gear housing, are in alignment. The steered wheels should be in
straight-ahead driving position (approximate check by placing a measuring bar against front and
gear rears. Take toe-in into account). A correction is then made by screwing ball joint and drag link
in or out.
NOTE
If a longitudinal correction must be made on steering linkage, the
cause might have been a previous, accident-like event. Inspect the
splining on the sector shaft (60) for distortion (pulling of pitman arm for
this purpose), the steering spindle for distorted installation or other
transmission components for bends or cracks.
Do not recondition distorted parts, discard and replace with new components.
8.1.1.3
Checking Play between Steering Nut (40) and Sector Shaft (60) in Center Position
(Pressure Point Adjustment)
a.
Turn steering to center position (refer to Para. 8.1.1.2) and pull drag link from pitman arm.
b.
must be 40 to 60 Ncm higher than outside the pressure point. For adjustment of pressure
point, refer to Section 5.
8.1.1.4
Checking Steering Lock
Attach drag link provisionally. Turn steering to the left up to lock. Disconnect drag link and check by
turning steering wheel further, whether there is a steering reserve. Repeat measuring by turning to
the right. There must be a steering reserve on both sides. If not, readjust wheel stop (wheel lock)
screws again. Reconnect drag link.
8.1.1.5
Reconnect Play of Steering Spindle Bearing
By turning steering wheel (shaking) back and forth, check for play. In the event of play, remove the
bearing bushing.
8.1.1.6
Check for Torsional Play or Hard-to-move Universal Joint or Companion Plate
between Upper Steering Spindle and Steering Gear
In the event of play (may result in audible rattling when moving back and forth) or reluctant
operation, install new part.
8.1.1.7
Check Steering Spindle and Jack Tube for Max. Permissible Distortion
Jack up steering axle. Remove steering wheel and also remove ball bearing sleeve from jacket
tube. Check permissible distortion of steering spindle and jacket tube according to Section 10.
