AUGER BELT INSTALLATION
WARNING!
Entanglement Hazard – Before performing any service procedures, make sure the engine is
off and remove the spark plug wire from the spark plug to ensure the engine cannot accidently start.
1.
Push the auger tension pulley arm to move the auger brake to allow access for installation of the belt
into the auger pulley.
2. Route the belt to the inside of the tension pulley, auger brake and install the auger belt onto the drive
pulley while pulling the auger housing into position with the main frame.
3. Install and/or tighten the hex nuts attaching the auger housing to the main frame. Tighten all fasteners
securely, do not over tighten.
4. With the belt installed on both pulleys and tension pulley in position, move the belt guide pin to
within 3/16 to 3/8 in. from the belt seated in the pulley and tighten the pin in position.
Note: The belt guide pin helps keep the belt in the pulley when the belt is disengaged. The pin should not
be tight to the belt. The pin should be loose enough to allow the belt to spin freely but not allow the belt to
jump off the pulley.
5.
Connect the upper cable to the auger control handle.
6. Install belt cover using (Qty. 2) hex screws.
WARNING! Ensure the belt cover is installed and all safety guards are in place before the engine is
started and at all times when the engine or machine are operating.
AUGER BELT AND RELATED COMPONENT INSPECTION
When replacing your snow blower auger belt, it is important to determine the cause of the failure (if
applicable) and take corrective action to avoid repeated failure.
Inspect the belt:
• Correct size and type • Fraying or peeling apart
• Missing pieces • Cracks and tears
• Burning • Uneven wear patterns
• General damage • Foreign material on belt, oil, grease, dirt etc.
Inspect the auger pulleys:
• Broken sheave or hub
• Loose or missing mounting bolts
• Bent or "out-of-round" condition (pulley doesn’t spin true)
• Misaligned pulleys
• Foreign material on pulleys, oil, grease, dirt, etc.
• Misaligned tension pulley
• Tension pulley loose or damaged
• Tension pulley and arm assembly operation
• Does the tension arm move freely both engaged and disengaged directions without binding?
