9. The length of the cardan shaft maximum driven apart (which is permitted for op-
eration) shall be of such type when the one part of the cardan shaft enters another for not
less than L
2
=150 mm. If the value is below L
2
=150 mm (Figure 5.8.4, view
А
) the cardan
shaft must not be operated. Sufficiency of overlapping L
2
can be checked by rotation or
lifting of the implement coupled.
Figure 5.8.4 – Choice of the cardan shaft length
10. If the tractor and the implement coupled are positioned linearly when the cardan
shaft is pushed in full, check if there is a sufficient clearance L
1
(Figure 5.8.4, view
В
) be-
tween tube face and universal joint yoke end butt. Minimum permissible clearance L
1
shall
make not less than 50 mm.
11. After the cardan shaft coupling regularize all the protective devices, meanwhile
fix the guard shaft housing from rotation with the chains as indicated in Figure 5.8.3.
12. Limit the RLL or FLL lifting to the uppermost position along with the implement
lifting when needed. It is essential for slope angle decrease, for exclusion of possibility of
contact and damage of the cardan shaft, and for providing of safety clearance between the
tractor and the implement.
13. Maximum permissible slope angles and steering angle (Figure 5.8.5) of the car-
dan shaft hinged joints are shown in Table 5.8.
