5.4.3.2 Operation 33. Checking / adjusting the clearances in the steering link joints
Figure 5.4.19 – Checking the steering wheel clearance
To check the free play and clearances in joints 5 (Figure 5.4.20) of the steering link
2, it is necessary to rotate the steering wheel in both directions with the engine stopped. If
there is the steering wheel angle clearance above 25° as shown in Figure 5.4.19, then re-
move clearances in the steering link joints according to following directions:
- apply the tractor parking brake;
- remove the cotter wire 3 (Figure 5.4.20);
- tighten the threaded plug 4 to remove the clearance in joint connection;
- lock the plug 4 with cotter wire 3.
- rotate the steering wheel in both directions. If the steering wheel clearance is
above 25°, i.e. the joints clearance was not removed by the threaded plugs 4 tightening,
then it is necessary to disassemble the joint 5 and replace worn parts. Assemble the joint 5
(tighten the plug 4 in such way, so the ball stud will rotate when the force from 6 to 12 N·m
is applied) and lock by cotter wire 3.
- when the steering link 2 is installed on the tractor, tighten the crown nuts 1 of ball studs
by torque from 100 to 140 N·m and install cotter wire. Meanwhile, the nut should not be un-
screwed when the nut slit and the ball stud opening are aligned.
