6.4.3.8 Task 34. Check/adjustment of clearances in steering joints
To check the backlash and clearances in steering joints 2 (figure 6.4.29) of the
steering link 1, 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
6.4.28, remove the steering joints play by performing the following actions:
- stop the engine;
- unscrew the bolts 3 (Figure 6.4.29), remove the cap 4 and the gasket 5;
- screw the plug 6 in to remove the steering joints play;
- start the engine and turn the steering wheel either side. In case the steering wheel
play is less than 25°, stop the engine, put the cap 4 back in its place fastening it with the
bolts 3, and centre-punch it into the hinge housing slot to prevent it from turning.
- if the steering wheel angular play is more than 25°, i.e. the steering joints play can
not be eliminated by retorque of the threaded plug 6, stop the engine, disassemble the hinge
and replace its worn-out parts. Assemble the hinge, the plug 6 shall be tightened with torque of
120 to 160 N·m, than unscrew it by 1/12…1/8 of turn and assembly the hinge completely, put-
ting the cap back in its place, and centre-punching the cap 4 into the hinge housing slot.
- after installation of the steering link tighten the ball pins castle nuts 14 with torque
of 100 to 140 N·m and fasten them by cotter, in case if the nut driving slot is matched with
ball pin bore unscrewing of a nut is not allowed.
