Checking and replacing V-belt and coupling
W A R N I N G
Warning of danger of detection/trapping in! Never attempt to check the V-belt
while the engine is running. Your hands could get caught between the V-belt and
the clutch. Serious hand injuries are the result.
N O T I C E
If the vibratory power of the machine - regardless of the number of operating hours
- suddenly decreases or stops completely during normal operation, first of all check
the V-belt and clutch.
Loose or worn V-belts reduce power transmission efficiency, result in poor compaction
performance and shorten the service life of the belt itself. Therefore, always check the V-belt
tension at the specified intervals.
17.5.1
Checking the V-belt tension
1.
Loosen V-belt cover screws (S) and
remove them.
2.
Check tension:
V-belt tension is OK if the belt yields
approx. 10 to 15 mm under
pressure with thumb and index
finger (see illustration on the left). If
the V-belt is too loose or too tight,
adjust the tension!
3.
Remount V-belt cover after having
checked/corrected V-belt tension!
17.5.2
Tensioning the V-Belt
The V-belt is tensioned by moving the engine block on the vibratory plate.
1.
Remove the V-Belt protection cover.
2.
Loosen the four nuts (M) securing the motor unit to the base plate until the motor can be
moved with the eccentric discs (S).
a.
Discs (S) in upper position = tighten the belt.
b.
Discs (S) in lower position = Loosen the belt.
3.
Once the belt has the correct tension, retighten the four nuts securing the motor unit to
the base plate.
4.
Finally, retighten the V-belt protection cover.
17.5.3
Changing the V-belt
1.
Loosen the V-belt.
2.
Then pull over the V-belt over the pulleys.
3.
Clean the drive wheels including the V-groove and the inside of the protective cover.
4.
Install the new V-belt and tension the V-belt again.
5.
Finally, reattach the V-belt protective cover.
