1d. Thread the screw into the tapped hole in the
outer half of the driven element sheave.
The end of the screw will press against
the inner half of the sheave, spreading the
two apart. See Figure 2.12.
Figure 2.12
NOTE: It is common practice among snowmobil-
ers to carry a spare belt. Belt life on this vehicle
should not be an issue, but if the utility vehicle is
operated in very remote areas, it may provide
some peace-of-mind for the operator. If they
choose to carry a spare belt, a suitable screw
and a 10mm wrench should be kept with it.
1e. As the sheaves are spread, the tension on
the belt will be relieved, and the belt can
be rolled-off of the driven element (pulley).
See Figure 2.13.
Figure 2.13
NOTE: On the Caterpillar engines, The belt may
be harder to roll off the sheave, but it will roll off.
1f. The belt can easily be installed by revers-
ing the removal process. See Figure 2.14.

NOTE: When the belt is installed, remove the
screw before operating the vehicle
NOTE: It may be necessary to start the vehicle, ,
and rev the engine in neutral to seat the belt.
2. Removal of the Driving element
NOTE: The driving element is most easily
removed after the belt is taken-off.
NOTE: The driving element can be removed
with the belt in place, but installation may require
the driven element sheaves to be spread unless
all three parts of the CVT are installed together,
as described later in this section.
NOTE: The bolt that holds the driving element to
the crankshaft can be reached by removing the
plastic cap from the end of the driving element.
If the driving element spins the crankshaft when
the tool is tightened it will be necessary to hold
the CVT or lock the crankshaft. One means of
holding the CVT involves removing the cover.
That is the technique described in this section.
2a. Disconnect and ground the spark plug
leads (Kohler) or un-plug the fuel shut-off
solenoid (Caterpillar).
