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 26). 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.

Figure 26. V-Belt Check

zReplacing the V-belt

Remove the belt cover. Engage an offset wrench (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.

zReinstalling 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.

zChecking 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.

zReplacing 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.

CAUTION:

Whenever the compactor's vibration becomes weak or lost during normal operation regardless of operation hours, check the V-belt and clutch immediately.

MVH-304GHB—MAINTENANCE

Vibrator Oil Level Check

CAUTION:

Alwayscleantheareaaroundthevibratoroillevel 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 27) 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.

Figure 27 . Vibrator Oil Maintenance Hydraulic Oil

1.Check hydraulic oil in every 100 hours of operation. With handle bar positioned vertically (storage position), remove bleeder plug (Figure 28) off the top of hydraulic pump and check for proper oil level.

2.Replace hydraulic oil after first 200 hours and in every 1,000 hours of operation.
