Toe-In Of The Wheels Of The Front Driving Axle; Adjustment Of Toe-In Of The Wheels Of The Front Driving Axle - Zetor CRYSTAL HD 150 Operator's Manual

Toe-in of the wheels of the front driving axle

The correct front wheel toe-in or toe-out of the tractor with the front drive axle is measured on the rims of the
wheels.
Toe-in or toe-out is determined by the difference in measured values.
Tractors with suspended front axle
The S-value varies with the height setting of the front of the tractor (see the section 'RUNNING
OPERATION').
The front of the tractor in the highest position
b = a - 3,3 to 4,2 mm
The front of the tractor in the middle position
b = a + 0,3 mm
The front of the tractor in the lowest position
b = a + 2,2 to 2,8 mm

Adjustment of toe-in of the wheels of the front driving axle

Note: Tractors are in standard equipped with hydrostatic device.
Set the wheel symmetrically with longitudinal axis of a tractor.
Measure the distance between rims in the front on horizontal level of wheel axis. Mark the place of
measurement.
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.
Release locking nuts of ball joint heads (2) of connecting rods of devices in hydraulic cylinder.
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).
Locking nuts of heads of ball joints (2), tighten with a torque of 122 - 136 N. Upper surfaces of heads
must be (1) parallel.
