Operation 30.
Check/adjustment of clearances in steering joints
To check the backlash and clearances in steering joints 1 (Figure 5.4.16) of the
steering link 4, it is necessary to turn the steering wheel either side when the engine is
running. In case the steering wheel angular play is more than 25° as indicated in Figure
5.4.15, remove the steering joints play by performing the following actions:
- stop the engine;
- remove locking wire 3 (Figure 5.4.16);
- screw threaded plug 2 to remove the steering joints play;
- locknut plug 2 with wire 3.
If the steering joints play can not be eliminated by tightening of threaded joints, take
the hinge joint to pieces and replace worn-out parts.
Besides, weak tightening of castle nuts of cone-shaped pins may be a reason for
increased steering wheel play angle of HSC hydraulic cylinders.
