MAINTENANCE (cont.)
Tensioning V-Belt(s)
Proper belt tension is critical to good performance.
Proper adjustment will assure long belt life. Too much or
too little belt tension will cause premature belt failure.
1.
Loosen the lock nuts B, leaving enough space
between the nut and bracket.
2.
Loosen 4 engine mount bolts (do not remove) only
enough to move the engine forward.
Note:
Two of the engine mount bolts are not shown in Fig. 13. They are located on the
opposing side of the engine deck.
3.
Push engine toward the back of the plate by
turning the adjustment bolts A to remove any
slack in V-belt(s). (Fig. 13)
WARNING! When adjusting the belt(s),
make sure that the clutch pulley is in
alignment with exciter pulley.
4.
Tighten the engine mount bolts.
5.
When the V-belt tension is correct, tighten the lock nuts B against the bracket.
6.
Replace the belt guard.
If the adjustment bolts run out of adjustment, the belt(s) may have to be replaced.
Replacing V-Belt(s)
Only fit A725 V-belts to this plate compactor. This type of V-belt is available as a
common spare part. Both V-belts should be replaced at the same time because
they will wear evenly through normal use. Work on one belt at a time.
1.
Loosen the lock nuts B and bolts A shown in above figure (Fig. 13).
2.
Loose 4 engine mount bolts (do not remove) only enough to move the engine forward.
3.
Slide the engine toward the front of plate and slip
the old V-belt(s) off of the pulley and install the
new V-belt(s) in their place.
4.
Position the V-belt(s) over the engine pulley.
5.
Move the engine back.
WARNING! When adjusting the belt(s),
make sure that the clutch pulley is in
alignment with exciter pulley.
6.
When the V-belt tension is correct, tighten the engine mount bolts and the lock nuts B.
7.
Replace the belt guard.
WARNING! When removing or installing the drive belt(s), be careful not to
get your fingers caught between the belt and pulley.
