2.3 Check of declutching cleanliness
After performing the above mentioned adjustments of clutch control, it is required to check
declutching cleanliness, for which do the following:
- engage the parking brake;
- start the engine and set diesel rated speed (1400±100) rpm;
- fully depress the clutch pedal and min in 5 sec engage GB ranges, the activation of which
shall be "clear" – without unwanted sounds and rattle.
In case there are unwanted sounds or rattle, it is required to check and if necessary,
make adjustments specified in sub-point 2.1 again.
After bleeding of the hydraulic system with the engine stopped, the total pedal 7 free
travel (Figure 5.4.19) shall make size Г that corresponds to displacement of lever 25 on the
radius of 120 mm by value Д.

5.4.3.2 Operation 32. Check / adjustment of clearances in steering joints

To check the backlash and clearances in steering joints 1 (Figure 5.4.21) of steering
link 4, it is necessary to turn the steering wheel to both sides when the engine is not run-
ning. In case the steering wheel has the backlash of more than 25° (the effort required for
steering wheel rotating shall be of (10±1) N) as shown in Figure 5.4.20, eliminate the steer-
ing joint clearance by performing the following actions:
- remove locking wire 3 (Figure 5.4.21);
- screw threaded plug 2 in to eliminate the steering joint clearance;
- lock plug 2 with wire 3.
If the steering joint clearance cannot be eliminated by tightening threaded joints, take
the hinge joint to pieces and replace the worn-out parts.
Besides, weak tightening of castle nuts of HSC hydraulic cylinder cone-shaped pins
may be a reason for increased steering wheel clearance angle.
