Front wheels toe-in
Proper toe-in of the front wheels of tractors with the front driving axle is 0 to 2 mm and is measured on the
front wheel hub flanges (if the front wheels are installed, you can measure toe-in on the wheel rims). Toe-in
'S' is determined by the difference of the measured values: S = b - a .

PGPPN096
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.
