Maintenance
Checking the V-Belts
V-Belts must be in good condition and tensioned properly to
ensure maximum performance of the plate compactor.
1. Remove the 4 hex bolts that secure the belt guard to access
the v-belts (see Figure 8).
2. Check the condition of the v-belts. If there is signs of
cracking, fraying or glazing, replace the belts as soon as
possible.
3. Check the belt tension by pressing on the center of the belt
length. The normal deflection on each side should be 3/8”
(9mm) - 1/2” (13mm) while applying moderate pressure
with thumb or finger.
Tensioning the V-Belts
1. Loosen 4 engine mount bolts, 2 on each end of the engine
block, just enough to move the engine slightly, but do not
remove the bolts entirely (see Figure 9).
2. Loosen the jam nuts leaving enough space between the nut
and the bracket (see Figure 10).
3. Push the engine toward the back of the plate by turning the
adjustment bolts to remove any slack in the v-belts.
4. When the v-belts are tensioned correctly, there should be 3/8”
(9mm) to 1/2” (13mm) of movement when the belt is pressed
firmly in the center of the belt length. If the adjustment bolts
can not be adjusted enough to increase the belt tension, then
the belts should be replaced.
5. Tighten the jam nuts against the bracket and tighten the
engine bolts.
6. Replace the belt guard.
Note:
When adjusting the belts, make sure that the clutch
pulley and the exciter pulley are in alignment.
