4. Checking and replacing V-belt and clutch:
22
Checking the clutch:
Check the clutch simultaneously when you check V-belt. With the belt cover removed, visually check
the outer drum of clutch for seizure, V-groove for wear or damage. Clean the V-groove as necessary.
Wear of lining and shoe should be checked through operation.
Worn shoe reduces transmission efficiency of engine rotation, causing a slip to occur.
Replacing the clutch:
Remove V-belt (See above for the procedure).
Remove bolt at the engine power output shaft end by giving a shock to a wrench (tap on with hammer)
engaged to it and turning it counterclockwise.
Pull out the clutch by means of pulley puller.
Reinstall the clutch with above procedure reversed. Turn-in the bolt securely by giving a shock to the
Checking the V-belt (See Fig.33)
In every 200 hours of operation, with the belt cover
(upper) removed, check the tension of V-belt. The
tension is normal if the bend is about 10mm when
the belt is pressed with our finger at midway
between the pulleys.
When the belt is slackened, transmission of engine
rotation will be deficient, resulting in poor compac-
tion and accelerated wear of the belt.
V-belt replacing procedure:
With upper and lower belt covers removed,
engage offset wrench (13mm) to vibrator pulley
tightening bolt (lower). Hook a piece of cloth at left
side midway of the V-belt and pull it back forcibly
while rotating the wrench clockwise until the belt
comes off.
Engage the V-belt to vibrator pulley at the bottom
and press the V-belt against left side of the upper
clutch. Same as in the case of removal, rotate the
offset wrench clockwise until the belt is installed.
There is a risk for injury. Use sufficient care for your hand not to be caught between the
belt and clutch. Use glove for protection.
NOTE:
！
If vibration is weakened during operation or vibration does not occur in spite of
engine running, conduct the check of V-belt and clutch regardless of maintenance
interval of 200 hours.
