5.1.5 – Drive belt tension
(must be carried out with the engine stopped)
Belt tension is given by the variation in pitch diameter of pulleys by
means of wedge sets. The drive pulley and the driven pulley are both
adjustable. To access the pulleys, disassemble the wheel, the wheel
casing and the belt casing.
Every 50 operating hours, check belt tension and adjust if necessary as
follows:
-
Disassemble the flange from the pulley Item
①
held by nuts Item
③
.
-
Remove a wedge Item
②
.
-
Reassemble the flange Item
①
placing the wedge Item
②
between
the flange and the nuts Item
③.
-
Progressively tighten the six nuts Item
③
, while rotating the pulley
manually so that the belt assumes its position without being stuck
between the two flanges.
If the resulting tension is not sufficient, repeat the operation
.
To guarantee proper belt alignment, the same adjustment must be performed
on each pulley.
When there are no more wedges between the flanges of the two pulleys and
the belt spins, the belt must be replaced with a new belt.
To assemble a new belt, fit all the wedges (2 per pulley) between the pulley
flanges.
Run a first belt tension check after 10 hours’ use of the machine, then check
and adjust tension if necessary every 50 hours.

When replacing or putting back a belt, check that the pulley
grooves are in proper condition and clean them as well as the
belt grooves thoroughly.
