MVH-406GH—MAINTENANCE
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.
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.
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. 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 light tap with a hammer to an engaged wrench and rotate bolt
counterclockwise. Remove clutch with a pulley extractor. To
reinstall, reverse the procedure.
Checking and Replacing the V-Belt and Clutch
1. After 200 hours of operation, remove the belt cover to check
the V-belt tension (Figure 30). 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.
Whenever the compactor's vibration becomes weak or lost during
normal operation regardless of operation hours, check the V-belt
and clutch immediately.

Vibrator Oil Level Check
1. In every 100 hours of operation, with the machine positioned
horizontally, use a 3/4” (19 mm) wrench and remove vibrator
oil level check plug (Figure 31). Visually inspect and see if
vibrator oil level is up to filler port. Use engine oil 10W-30 for
lubrication. Capacity of the lubrication oil is 20.3 fl.oz (600cc).
Be sure to clean area around check hole to prevent dirt and
dust from entering.
Draining Vibrator Oil
1. Replace vibrator oil after first 200 hours and in every 1,000
hours of operation.
2. Position handle bar vertically (storage position).
3. Using a 14 mm wrench remove the vibrator oil drain plug
(Figure 31) from the vibrating plate assembly.
Always clean the area around the vibrator oil level check plug
before removing oil check plug. This will prevent dirt and debris
from entering the system.
CAUTION
For draining oil through level check hole, have
the machine inclined with a sleeper or the like
placed under the compaction plate on opposite
side.
4. After hydraulic oil has been completely drained from
machine, fill with 10W-30 motor oil to the appropriate safe
operating level (Figure 31).
5. Reinstall drain plug into vibrating plate assembly. Apply seal
tape or Loctite #575 to thread portion of drain plug.
Draining Hydraulic Oil
1. Disconnect the hydraulic hose (Figure 32) connected to the
hydraulic oil cylinder.
