Checking and Replacing the V-Belt and Clutch
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 20) when depressed with finger at midway between
the clutch and vibration pulley shafts.
1. To check the V-belt tension (Figure 19), remove
upper
belt
cover.

Replacing the V-belt
1. Remove the belt cover.
2. Engage an offset wrench (13 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.
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 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.
3. If the V-belt becomes worn or loose, replace the belt. A loose
V-belt will decrease the power transmission output, causing
reduced compaction and premature wear of the belt.
