Maintenance Instructions REPLACING/REPAIRING
REPLACING/REPAIRING Gearbox Replacement
Remove and replace the gearbox as follows:
1. Remove the gearbox cover. Two (2) bolts (one
on each side) fasten the cover to mounting tabs
on the frame.
2. Loosen the set screw fastening the PTO U-joint
to the gearbox shaft and slide the PTO shaft off
the gearbox shaft.
3. Remove the two (2) bolts, oblong washers, and
Keps nuts that fasten the gearbox to the snow-
blower frame.
4. Remove the gearbox from the snowblower
frame.
NOTE: The flexible coupling spider will be
loose; be sure to keep track of it. A good way to
do this is to tape it in place on the flexible cou-
pling half that is attached to the drive shaft.
5. Replace the gearbox by reversing the removal
procedures.
WARNING
To prevent accidental engine starting
when replacing parts or repairing the ma-
chine, remove the key from the ignition
switch and disconnect the fuel solenoid
wire [diesel engines] or the spark plug
wire(s) [gasoline engines].
CAUTION
ALWAYS use genuine factory replace-
ment parts. Substitute parts CAN result
in product malfunction and possible inju-
ry to the operator and/or others.
