Rear Wheel Track Formation - Belarus 1822.3 Operator's Manual

4.2.9 Rear wheel track formation

The rear wheel track with the wheels of basic configuration 580/70R42 is changed by
moving the hub together with the wheel over the axle shaft and by replacing the wheels from
one sideboard to the other one.
To change the rear wheel track perform the following operations:
- put the tractor on a level ground, put the stops under the front and rear wheels, clean
the axle shafts from dirt;
- jack up the corresponding axle tube;
- release four tie bolts 1 (figure 3.13.1) of the inserts 3 and 4 (two on each insert) by
three full revolutions. The other bolts are to be screwed out. Screw the bolts of the inserts in
the thread holes for disassembly;
- if it is impossible to squeeze the inserts out by means of disassembly bolts 1, fill kero-
sene or other liquid penetrant in places where inserts are detached from the hub body, wait for
some time and then screw the disassembly bolts in, simultaneously knocking on the hub body
until the inserts fully squeeze out;
- move the hub to a required track (use the table 4.5 to set the track "K" (figure 4.2.3) by
way of measuring the dimension "L" from the axle shaft end to the insert end face);
- screw the tie bolts out of the disassembly holes and screw them into the inserts.
Tighten the bolts with a torque of 550 to 600 N·m in several stages until all bolts are tightened
with the required torque;
- set the track for the other wheel by analogy;
- check and tighten the tie bolts after the first operation hour, then after the first eight –
ten operation hours and after every consecutive 125 hours of operation. If the wheels were
removed during changing the rear wheel track, mounting them back tighten the securing nuts
with a torque of 700 to 750 N·m and check the wheel securing nuts for tightening after the first
operation hour, after the first eight – ten operation hours and every subsequent 125 hours of
operation.
ATTENTION: AFTER TIGHTENING THE BOLTS MAKE SURE THE END SURFACES OF
THE UPPER AND LOWER INSERTS DON'T JUT OUT WITH RESPECT TO EACH OTHER BY A
VALUE OF 1...2 MM!
