8.13 MOUNTING THE BELT
The mounting of the belt is shown on Fig.
8.13.11. Putting the belt is possible when the
tensioner is in starting position:
- loosen the nuts pos.2
- loosen enough the nuts pos.3 (or unscrew
them).
- unscrew the nut (pos.4) and pull out the
bush (pos.5) from hole D in the tensioner (pos.1),
that will allow the tensioner to have the position in
Fig. 8.13.11.
- put the belt following steps shown on Fig.
8.13.2; Fig. 8.13.3 and Fig. 8.13.4. (It is possible also
to put the belt on the
roller unit assembly as a last
step.) Check if the belt is on the
right place in the
grooves of each of the pulley units
and on the central
pulley.
Put back the tensioner in a position the axle
bushing to fit in the tensioner hole (Fig. 8.13.5) (You can push down the bush screwing the nut pos.4)
Tighten the nuts (pos.2, Fig. 8.13.1) on the sectors and unscrew half rev. (Fig. 8.13.5).This will allow the tensioner
turn in minimum clearance. Fast light the belt (Fig. 8.8.7) in order to achieve the right position and then tighten the nut in the
center of the tensioner (Fig. 8.13.6). Fast up the belt taking care of the tensioning (Fig. 8.13.7).
It is recommended that the tensioning of the belt be measured with Optikrik II Device (Measuring range: 500-1400 N) (Fig.
.13.8).
For a new belt the tensioning force is
650N. Тhe tension of the existing belt must be 520 N.
ATTENTION: NEVER “OVER” TENSION THE BELT, THE BELT WILL BE DAMAGED AND IT WILL NEVER RECOVER ITS
ORIGINAL TENSION
Tighten the two nuts on the sectors and contra nut on the tensioner (Fig. 8.13.10). Put the seal ring on the bottom cover and
close the machine (Fig. 8.13.11).
Reassemble in the same manner.
