MVH-200GH — MAINTENANCE
Vibrator Oil Level Check
1. In every 100 hours of operation, with the machine positioned
horizontally, remove vibrator oil level check plug
(Figure 26) off vibrator (19 mm wrench) and see if oil is up to
filler port. Be sure to clean area around check hole to prevent
dirt and dust from entering.
2. In every 300 hours of operation, replace oil (capacity 1,500
cc). 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.
* Use engine oil 10W-30 for this lubrication.
Always clean the area around the vibrator oil level check hole
before removing oil check plug. This will prevent dirt and debris
from entering the system.
Checking and Replacing the V-Belt and Clutch:
After 200 hours of operation, remove the belt cover to check the
V-belt tension (Figure 24).
Figure 24. V-Belt Check
CAUTION - Checking and Replacing the V-Belt
NEVER attempt to check the V-belt with
the engine running. Severe injury can
occur if your hand gets caught between
the V-belt and the clutch. Always use
safety gloves.
Checking the Clutch
1. With belt cover removed, visually check outer drum of the
clutch for seizure and "V" groove for wear or damage.
2. Clean the "V" groove as necessary.
3. Check the clutch lining and shoe for signs of wear. If the shoe
is worn, replace the clutch to prevent deficient power
transmission and slippage.
Replacing the Clutch
1. Remove V-belt.
2. Remove bolt at engine power output by giving a shock to an
engaged wrench (e.g. tapping with hammer) and rotate the
bolt counterclockwise.
3. Remove clutch with a pulley extractor.
4. To install a new clutch, reverse steps 1-3.
Checking the V-belt
1. Tension is proper if the belt bends about 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
1. Remove the belt cover.
2. Engage an offset wrench (19 mm) or the like to vibrator pulley
(lower) fastening bolt.
3. 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.
4. Check the clutch and replace as necessary, following the
procedures listed in
Checking the Clutch
.
5. Engage V-belt to lower vibrator pulley and push the V-belt to
the left side of the upper clutch and the rotate offset wrench
clockwise so that the V-belt moves onto the pulley.
