MAINTENANCE
CHECKING AND REPLACING THE V-BELT AND
CLUTCH
After 200 hours of operation, remove the belt cover to check
the V-belt tension (Figure 28). Tension is proper if the belt
bends about 3/8”(10 mm) when depressed strongly with
finger between shafts. Loose or worn V-belts reduces power
transmission efficiency, causing weak compaction and
reduces the life of the belt itself.
Replacing the V-belt
Remove the belt cover. Engage an offset wrench 3/4”(19
mm) or the like to vibrator pulley (lower) fastening bolt.
Engage waste cloth or the like at midway of V-belt on the
left side and while pulling it back strongly, rotate the offset
wrench clockwise so that the V-belt will come off.
Reinstalling the V-belt
Engage V-belt to lower vibrator pulley and push the V-belt
to left side of upper clutch and, in the same manner as in
removal, rotate offset wrench clockwise so that the V-belt
goes back on.
Checking Clutch
Check the clutch simultaneously with V-belt checking. With
belt cover removed, check outer drum of the clutch for
seizure and "V" groove for wear or damage with your eyes.
Clean the "V" groove as necessary. Wear of lining or shoe
should be checked with running check. If the shoe is worn,
power transmission becomes deficient and slipping will
result.
Replacing Clutch
Remove V-belt. Remove bolt at engine power output by
giving a shock to an engaged wrench (tapping with hammer
or the like)and rotating bolt counterclockwise. Remove
clutch with a pulley extractor. To reinstall, reverse the
procedure.
VIBRATOR OIL LEVEL CHECK
In every 100 hours of operation, with the machine
positioned horizontally, use a 14 mm wrench and remove
vibrator oil level check plug (Figure 24). Measure oil level
with gauge. Vibrating oil capacity is 0.63 quart (0.6 liters).
Be sure to clean area around check hole to prevent dirt
and dust from entering.

CAUTION — Weak Vibration
Whenever the compactor's vibration becomes weak or
lost during normal operation regardless of operation
hours, check the V-belt and clutch immediately.
CAUTION — Dirt and Debris
Always clean the area around the vibrator oil level cleck
plug before removing oil check plug. This will prevent
dirt and debris from entering the system.
