OPERATION 41
CAB SUSPENSION ADJUSTMENT
(where fitted)
On tractors with a suspended cab the pre--load on
the suspension unit (1) Figure 109, may be adjusted
to suit heavier or lighter weights carried in the cab.
NOTE: Depending on track setting, the tractor rear
wheel may need to be removed for easy access to
the cab suspension adjuster.

Suspension Setting

The pre--load adjuster is used to set the cab
suspension so it operates in the optimum comfort
zone for normal driving conditions. Position II
provides the ideal setting for a 68kg (150 lbs.)
109
operator plus additional equipment weighing 22kg
(48 lbs.) carried in the cab.
NOTE: To provide optimum suspension
performance, the weight of any heavy items carried
in the cab (tow chains, linkages, toolboxes etc.) must
always be taken into consideration when adjusting
the suspension.
The cab suspension adjustment has five pre--load
settings which can be 'clicked' into position by
rotating the upper pre--load adjuster. Each setting is
identified by vertical markings (2) on the lower collar.
When adjusted correctly, the arrow on the upper
collar (1) will align with the vertical markings on the
lower collar.
Select position I for operators having a lighter body
weight than 68kg (150 lbs.), positions III and IIII are
used for operators with a heavier body weight. With
two people in the cab, positions IIII and IIIII should be
used.

IMPORTANT: For correct suspension operation it is
vital that both suspension units are adjusted to the
same setting. An imbalance in adjustment will cause
unnecessary wear on the suspension units.
A 'C' spanner is included in the tractor tool kit for
adjusting the cab suspension. Engage the 'C'
spanner in the slot of the pre--load adjuster and rotate
to the desired position.
NOTE: Use only the special tool provided to carry out
any pre- -load adjustment, using alternative
equipment may damage the adjuster components.
