SECTION 3 -- FIELD OPERATIONS
3--32
WHEEL TRACK ADJUSTMENT
FRONT WHEEL TRACKS 2WD
To adjust the front wheel track, proceed as follows:
-- raise the front of the tractor using a jack
positioned in the middle of the axle;
-- release the sliding ends after removing the
retaining bolts and nuts (1) and (2) fig. 44, two on
each side
(tightening torque: 220 Nm - 22.5 kgm);
-- adjust the length of the steering rods connecting
the two wheels by removing the locking screws
(3) fig. 46 (tightening torque: 39 Nm - 4 kgm);
-- this provides seven possible wheel tracks, as
illustrated in fig. 47.
A further larger track width (maximum track) can be
obtained by reversing the wheels on their hubs. Only
use this maximum track where absolutely necessary.
The tightening torque of the wheel to hub locknuts is
115 Nm (11.7 kgm).
WARNING
If the tractor has hydrostatic steering, proceed as
described above for the left--hand wheel. For the
right--hand wheel, however , after releasing the
sliding end of the axle, you must change the
hydraulic cylinder’s internal angle, as appropriate, in
the following way:
-- slacken the cylinder hose connectors;
-- keep screw (3) fig. 45 loosened;
-- insert angle adjuster pin (1) fig. 46 in one of the
corresponding holes (2) fig. 46.
-- tighten the pin
(tightening torque: 294 Nm - 30 kgm)
-- tighten screw (3) fig. 46
(tightening torque: 39 Nm -- 4 kgm).
-- check that the hoses are not twisted and tighten
the connectors.
