MAINTENANCE
TRACTION CONTROL CABLE ADJUSTMENT
Initial Adjustment
1. Lift the bellcrank arm up as far as it will go (see Figure 34).
2. While holding the bell crank arm up, adjust the cable until all the slack
is removed.
3. Back the adjustment screw out 7-8 turns. Tighten nut.
4. Start engine and check that the system disengages when the control is
released.
WARNING: Do not over-tighten, as this may cause
traction drive to engage without depressing the
traction drive control (bellcrank arm must remain in
down position).
Verify that the cables are not over-tightened: With
speed selector in position 1 and traction drive
control fully released, push snowthrower forward.
The unit should move forward freely.
If unit does not move forward freely, the cable has
been over-tightened. To remedy, loosen tension on
clutch cable slightly, and recheck.
Run-In Adjustment
1. After 5 hours of use, check for proper adjustment.
2. Readjust clutch cable if necessary by increasing tension on cable. A
small amount of bellcrank arm movement is permissible if unit passes
operating checks described in the Warning above.
EASY-TURN™ CABLE ADJUSTMENT
If the Easy-Turn™ cable has stretched, the gears will not disengage when
the control lever is activated. Adjust the cable using the following proce-
dure.
1. Turn the engine off and disconnect the spark plug wire.
2. Loosen the jam nut (see Figure 35).
3. Turn the adjustment nut to lengthen or shorten the cable. The cable
should be tightened just until all slack is removed from the lever,
however it must not engage the Easy-Turn™ release without depress-
ing the control lever.
4. Tighten the jam nut.

AUGER SHEAR PIN REPLACEMENT
The augers are secured to the auger shaft with special shear pins that are
designed to break if an object becomes lodged in the auger housing. Use
of a harder grade shear pin will reduce the protection provided by the
shear pin.
WARNING: Do not go near the discharge chute or auger
when the engine is running. Do not run the engine if any
cover or guard is removed.
Under most circumstances, if the auger strikes an object which could
cause damage to the unit, the shear pin will break. This protects the gear
box and other parts from damage.
The shear pins (A A , Figure 36) are located on the auger shaft. Replace a
broken shear pin as follows.
1. Tap out the broken shear pin with a pin punch.
2. Install a new shear pin and cotter pin. Bend the ends of the cotter pin
down.
IMPORTANT: Do not replace shear pins with anything other
than the correct grade replacement shear pin. Use of bolts,
screws, or harder grade shear pins can result in equipment
damage.
CHECK THE TIRES
Check tires for damage. Check the air pressure in the tires with an accurate
gauge (see Figure 37).
CAUTION: Avoid Injury! Explosive separation of tire and
rim parts is possible when they are serviced
incorrectly.
• Do not attempt to mount a tire without the proper
equipment and experience to perform the job.
• Do not inflate the tires above the recommended
pressure.
• Do not weld or heat a wheel and tire assembly. Heat can
cause an increase in air pressure resulting in an
explosion. Welding can structurally weaken or deform
the wheel.
• Do not stand in front or over the tire assembly when
inflating. Use appropriate tool that allows you to stand to
one side.
NOTICE: Check side of tire for maximum tire pressure. DO
NOT exceed maximum.
