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 protects the gear
box and other parts from damage.
The shear pins (A A , Figure 41) 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 42).
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.
