V-Belt Check
1. To check the V-belt tension, remove the three bolts that secure
the belt cover to the frame as shown in Figure 22.
Figure 22. V-Belt Cover Removal
3. A loose V-belt will decrease the power transmission output,
causing reduced compaction and premature wear of the belt.
4. If the V-belt becomes worn or loose, replace it .
Figure 23. V-Belt Tension
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.
2. The V-belt tension is proper if the V-belt bends 10 to 15 mm
(Figure 23) when depressed with finger at midway between
the clutch and vibration pulley shafts.
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 tapping 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.
Replacing the V-belt
1. Remove the belt cover.
2. Place an offset wrench (13 mm) or the like on the vibrator
pulley (lower) fastening bolt.
3. Using a waste cloth or the like, pull the V-belt back strongly at
midway of the belt on the left side and 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. Place the V-belt on the lower vibrator pulley. Push the V-belt
to the left side of the upper clutch and rotate the offset wrench
clockwise so that the V-belt moves onto the pulley.
