4.4 DRIVE BELT ADJUSTMENT
If it seems that the forward drive is not working
properly after a long period of use or after replacing
the belt, this may be caused by a change in the
length of the belt.
– A loose belt reduces output from the drive and
limits forward movement power;
– a belt which is too tight increases noise and
results in jerky movements or tipping up when
engaging the drive.
In these cases the stretcher will need to be adjust-
ed.
The stretcher can be accessed from the inspection
hatch beneath the seat; adjust the tension of spring
(1)
using nuts
(2)
to set length «
A
» of:
– 114 ÷ 116 mm
➤
in mechanical drive models
– 109 ÷ 111 mm
➤
in hydrostatic drive models
measured from the outer ends of the springs with the
drive commands disengaged.
Following adjustment, fully tighten the nuts
(2)
and the
locknut
