MVH-402DSB — MAINTENANCE

Engine Oil Replacement:

1.Replace engine oil, first in 25 hours of operation and every 50 to 100 hours afterwards.

2.Oil may be drained more easily when it is warm after operation (For more details, see separate engine Owner's Manual).

Air Filter

1.The air filter element should be cleaned because a clogged air cleaner can cause poor engine starting, lack of power and shorten engine life substantially.

Figure 18. Engine Air Filter and Element

2.To clean or replace air filter loosen the wing nut on the air filter housing (Figure 18), remove the cover and take out air filter cartridge. If only cleaning of the air filter is desired blow through the air filter cartridge from the inside, moving a jet of dry compressed air up and down until all dust is removed.

CAUTION

NEVER attempt to check the V-belt with the engine running. Severe injury can occur if your hand gets caughtbetweentheV-beltandtheclutch(Figure19). Always use safety gloves.

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.

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 20). 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.

CAUTION
