Front Wheels Toe-In; Adjustment Of Toe-In Of The Wheels Of The Front Driving Axle; Front Drive Axle Fenders - Zetor MAJOR Operator's Manual

Front wheels toe-in

The value of toe-in of front wheels taken on the rim of
a tractor:
With driven axle 0 to 4 mm
'S' toe-in is given by the difference of measured values:
S = b - a.
Before checking toe-in, it is necessary to check
or adjust the clearance in front wheels bearings and
inflate front tires to prescribed pressure.
The measurement of toe-in is done on wheel rims.

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.

Front drive axle fenders

Are on adjustable holders which can be set both
horizontally (by relocating screws 'a' to different holes) and
vertically (by relocating screws 'b' to different hole) based
on requested wheel tracks and the kind of used tires.
