Transmission System Adjustment
If the friction wheel is changed or the snow blower requires more
force to the ground to push snow, follow the procedure below to
setup the transmission system. Remove key, remove spark plug
cable from spark plug and ground to the engine.
1. Inspect the transmission engagement handle. The handle
should have approximately 60 degrees of travel to ensure the
correct transmission tension can be applied. The return stop
tab may need to be bent to achieve the 60 degree opening.
2. Set the transmission speed lever to F6.
3. Remove the headlight to gain access for adjustments. See
more details in the headlight removal procedure.
4. Put snow blower into the vertical service position standing on
the front of the collector housing as instructed in the service
position page of the manual.
5. Remove the bottom cover (6 bolts) with a 10mm wrench or
socket/ratchet. See diagram in Inspection and Replacement of
Transmission Drive Belt.
6. Back the upper jam nut off of the threaded metal tube and
tighten the lower jam nut against the threaded metal tube.
Using pliers and 8mm wrench.
7. Adjust the threaded metal tube to achieve the correct
clearance between the friction wheel and drive disc.
Clockwise applies more tension to the friction wheel and
transmits more power to the ground.
Counter-clockwise relieves tension to the friction wheel
and transmits less power to the ground.
Adjust until two stacked pennies or other 1/8 inch thick
gauge will barely fit between the drive disc and the
friction wheel.
If unit is to be used on inclines exceeding 5 degrees, turn
the threaded metal tube clockwise one full turn after
removing the pennies or gauge. Note that this may
increase friction wheel wear. Transmission maintenance
will be required each season. It is recommended that a
spare friction wheel be ordered: GXi part number B02510.
8. Tighten the upper jam nut against the threaded metal tube and
remove the pennies.
9. Reassemble by reversing the disassembly steps above. Make
certain all connections are properly tightened.
