Adjustment of toe-in of the wheels of the front driving axle
C507
Note: Tractors are in standard equipped with hydrostatic device.
z Set the wheel symmetrically with longitudinal axis of a tractor.
z Measure the distance between rims in the front on horizontal level of wheel axis. Mark the place of
measurement.
z Travel forward with a tractor so that the marked places would be on horizontal level of rear wheel axis
(turn by 180°) and remeasure the distance between marked places.
z Release locking nuts of ball joint heads (2) of connecting rods of devices in hydraulic cylinder.
z Adjust toe-in by turning the pin of ball joint (3). Do the adjusting symmetrically with both joints to keep the
same lock of wheels to both sides (do the measurement on the sides of rims).
z Locking nuts of heads of ball joints (2), tighten with a torque of 122 - 136 N. Upper surfaces of heads must
be (1) parallel.
Front drive axle fenders can come in two designs
A - Fenders with solid consoles where the axis of fenders
turn corresponds with the axis of front wheel turn. Fenders
are on adjustable holders that can be set according to
required tracks and the type of tyres used on the side (by
relocating screws (a) to different openings) and also in
terms of height (by relocating screws (b) to different
openings).
B - Fenders with turnable consoles where the axis of
turning corresponds to the axis of front wheel only
partially. This design enables the setting of greater front
wheels lock. Fenders are on adjustable holders which can
be set according to the kind of tyres used in terms of
height (by relocating screws (b) to different openings).

Set the stops always with any wheel track change or tire
replacement with front drive axle.
Wheel stops with front drive axle must be set so that there
would be a distance of at least 50 mm between front drive
axle tires and tractor with full lock and full axle swing
around central pin.
Setting wheel stops with front drive axle check
1. Set full lock to one side and check that the distance
between a tire and the nearest solid point on the tractor is
at least 50 mm. Check both front tires.
2. Turn the steering to full lock to the other side and check
according to point 1.
3. Heave one side of the front axle to the maximum swing
(front axle leans against the bracket) and check according
to point 1 and 2.
4. Hoist the other side of front axle to the maximum swing
(front axle leans against the bracket) and check according
to point 1 and 2.
