Rear wheel track formation
1. Jack up the rear part of the tractor so
that the wheels leave the ground.
2. Unscrew the nuts (1) and remove the
wheels.
3. Loosen by 2…3 turns the tie bolts (2)
of the upper and lower wheel hub liners
(3).
4. With the four extracting bolts
screwed into the upper and lower liners
(two bolts on each liner), pull the liners (3)
from the wheel hub to release the cone
clamp and wheel hub to let the hub move.
5. Move the hub along the semi-axle to
obtain the required track L (use the tables
at the right side to determine the track by
measuring the size K from the semi-axle
end to the liner end).
6. Remove the extracting bolts and
tighten up the bolts fastening the hub.
7. Install the wheel and repeat the
operation for the opposite rear wheel.

and wheels disks, follow figure H-2.
