Replacing the V-belt

„„Remove the belt cover (Figure 29). Engage an offset wrench 3/4”(19 mm) or the like to vibrator pulley (lower) fastening bolt. Engage wastecloth or the like at midway of V-belt on the left side and whilepulling it back strongly, rotate the offset wrench clockwise so that the V-belt will come off.

Reinstalling the V-belt

„„Engage V-belt to lower vibrator pulley and push the V-belt to leftside of upper clutch and, in the same manner as in removal, rotate offset wrench clockwise so that the V-belt goes back on.

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.

CAUTION

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