8.1.2. TENSIONING A USED TREAD BELT
Figure 8-3
1. Before slackening a used tread belt that needs
to be re-
tensioned, place a tape measure
a
long the centre of the tread belt and use a
pen to make two reference marks spaced
exactly 1m apart.
Figure 8-4
2. After reassembling the used tread belt, lock
down by turns the 2 screws (a)
distanc
e between the two reference marks
made previously on the tread belt are once
again spaced 1m apart.
Take care that the roller is always
approximately parallel with the one on
the front, to counteract the tension
exerted by the belt on the roller
bearings.
This procedure is normally carried out
after replacing the rear or driving roller,
or in cases where a used tread belt needs
to be reassembled.
CAUTION: After completing this
procedure, check the centring of the
tread belt as instructed in paragraph:
8.2. āCentring the tread beltā.
