DRIVE CHAIN REPLACEMENT
1. Wait for engine to cool and disconnect spark plug.
2. Place a block of wood, or another object that will support and
steady the unit under the axle on the side of the machine you will
be working on.
3. Remove the two screws (item #103) holding the chain guard (item
#104) and then remove the chain guard.
4. Loosen the two nuts (item #98) holding the bearing (item #97).
(See
Fig
. 7)
5. Remove the retaining ring holding the wheel on and then slide the
wheel off.
6. Replace the chain (item #105). Remove the old chain by walking it
off the sprockets.
7. Position the bearing so that it applies the proper tension to the
chain and tighten the nuts holding the bearing
NOTE:
DO NOT
over tighten the chain, as this will cause premature failure.
Likewise, if the chain is too loose it will come off when the drive is
engaged.
8. Reassemble the machine using steps 1-4 in reverse order.
BELT REPLACEMENT
1. Wait for engine to cool and disconnect spark plug.
2. Follow the impeller removal steps (2-5 on page 8)
.
3. Remove the four bolts (item #8) holding the back plate (item 4) to
the back housing (item #6).
4. Loosen the nut on the idler pulley and slide it to the right to
relieve tension on the belt. (See
Fig
. 6)
5. Slip the belt (item #86) off the engine pulley and the transmission.
6 Replace the belt with a new one and slide the idler pulley to put
proper tension on the belt.
NOTE
: Do not place too much tension
on the belt, as it will cause premature failure.
7. Reassemble the machine in reverse order.
NOTE
: You will need
to replace the impeller bolt and torque to the proper specifications
see page 12.
DO NOT
use the old impeller bolt.
8. Reconnect spark plug wire.
CLUTCH CABLE ADJUSTMENT
1. With the machine off, loosen the two nuts on the end of the clutch cable (item #111) going in to the transmission.
2. By moving the position up or down on the threads it will change the tension on the clutch lever (item #113).
NOTE:
Do
not position it too high on the threads as this could cause the drive not to engage. Likewise, if it is placed too low the
drive may stay permanently engaged. The optimum setting is to remove any slack in the clutch cable when disengaged.
The travel of the clutch control will apply the correct spring force on the cone clutch. Once the desired position is in
place, tighten the nuts securely.
3. Start the machine and check the operation. If the drive cable is not engaging properly, shut the machine off and
reposition the nuts on the cable to tighten the drive cable.
