Multiquip MVH-200DA manual Checking and Replacing the V-Belt and Clutch, Checking the V-belt

Checking and Replacing the V-Belt and Clutch:

After 200 hours of operation, remove the belt cover to check the V-belt tension (Figure 19).

Figure 19. V-Belt Check

CAUTION - Checking and Replacing the V-Belt

NEVERattempttochecktheV-beltwith the engine running. Severe injury can occur if your hand gets caught between the V-belt and the clutch. Always use safetygloves.

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 theV-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.

MVH-200DA — MAINTENANCE

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.RemoveV-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.

Vibrator Oil Level Check

CAUTION - Checking and Replacing the V-Belt

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.

1.In every 100 hours of operation, with the machine positioned horizontally, remove vibrator oil level check plug (Figure 20) 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.
