Checking and Replacing the Clutch
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. Place a 19 mm offset wrench or the like onto the lower vibrator
pulley fastening bolt.
2. While pulling back hard on the V-belt near the lower vibrating
pulley, rotate offset wrench clockwise so that the V-belt slips
off the lower vibrator pulley. Set V-belt aside.
3. Remove bolt at engine power output by giving a shock to an
engaged wrench (e.g. tapping with hammer) and rotate the
bolt counterclockwise.
4. Remove clutch with a pulley extractor.
5. To install a new clutch, reverse steps 1-4.
Check hydraulic oil in every 100 hours of operation. With handle
bar positioned vertically (storage position), remove breather plug
(Figure 1) off the top of hydraulic pump and check for proper oil
level.
Replace hydraulic oil after first 200 hours and in every 1,000
hours of operation.
1. After removing plug cap of hand pump (Figure 10), remove
plug of breather (24 mm wrench) and disconnect vibrator
side of hydraulic hose (Figure 22) at vibrator cylinder. With
travel lever placed in the
FORWARD
position, drain hydraulic
oil in the pump.
Make sure hydraulic oil in hand pump is at a normal save
operating level. DO NOT over fill. Over filling (excessive oil)
will cause excess oil to blow out of breather plug.
2. After draining, reconnect the hydraulic hose to vibrator.
3. Fill oil through breather hole of hand pump. (Capacity: About
300 cc). Use
Shell Tellus Oil #46
or equivalent
4. Removing breather plug at vibrator cylinder causes oil to
flow out of breather hole in a while. When aeration
disappears, replace the plug and tighten securely.
5. Replace breather plug of hand pump and fit the plug cap.
After making sure that oil in pump is at proper level, replace
the breather plug.
