MAINTENANCE
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 pro-
tects the gear box and other parts from damage.
The shear pins (A, Figure 19) are located on the auger shaft. Re-
place 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 20).
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.
