Adjustment is carried out as follows:
1. Set the necessary tire pressure in accordance with the subsection “Selection of optimal
inner pressure in tires depending on operational conditions and load on tractor axles” of
section 4 “Intended use of tractor”.
2. Set the front wheels in straightforward position that correspond to straight move-
ment by way of driving the tractor straight ahead for at least 3 meters along the horizontal
level ground with a hard surface and then stopping. Engage the parking break to avoid trac-
tor movement.
3. Measure distance “А” (Figure 6.4.17) at the height of wheel centers at the front,
and make visible marks in measurements points.
4. Disengage the parking brake, move the tractor forward in such a way that the front
wheels turn by half revolution and measure distance “B” between rim edges on wheel center
level from behind in the points determined and marked before.
5. If the value (“B”-“A”) ranges within 0 to 8 mm that means that the toe-in is correctly
adjusted. If the value (“B”-“A”) is less than 0 or more than 8 mm, do the following:
a) leaving the tractor position unchanged, unscrew lock nuts 1 and 3;
b) by rotating steering link tube 2 make the value (“B”-“A”) fit into range from 0 to
8 mm;
c) repeat operations, described in subparagraphs 4 and 5.
d) if value (“B”-“A”) falls within the limits of 0 to 8 mm, tighten steering link lock nuts 1
and 3 with torque of 100 to 140 Nꞏm, leaving steering link length unchanged.
1, 3 – lock nut; 2 – adjusting tube of steering link.
