4.2.11.3.2 Front wheel track formation of tractors, equipped with FDA with bevel
wheel gear groups and HPS.
Wheel track of tractors equipped with FDA with bevel wheel gear groups can be
changed stepless, regardless of the lengths of extension of wheel gear groups (dimension
А in figure 4.2.16) and can make from 1400 to 1600 mm, and with re-placing the wheels
from one sideboard to the other from 1750 to 1900 mm (with front tyres 11.2-20 mounted).
Figure 4.2.16 – Rules of changing the front wheel track of tractor with FDA 72-
2300020-А mounted
To set the necessary track by means of extending the wheel gear groups, do the
following:
- brake the tractor using the parking brake. Put wheel chocks at the front and back
of rear wheels;
- jack up the front part of the tractor (or the front wheels, one by one) to provide
clearance between the wheels and the ground;
- release four bolts fastening the cover of adjusting screw and remove cover 2 (fig-
ure 4.2.17);
- unscrew two nuts and remove two wedges 1;
- loosen the tightening of nuts 3 at the ends of steering link tube 5;
- remove split pin 7, and then remove lock-pin 6. If distance "H" is larger than
70 mm, change the position of lock finger 6 (position II);
- by rotating adjusting screw 4 with a wrench, move the body of the bevel pair with a
hub drive to reach the necessary distance "A". At the same time, by rotating tube 5,
change the length of the steering link to the dimension that corresponds to the track that is
being set up.
