2. Compatibility
This auger drive belt is compatible with a range of Murray snowthrowers. Verify your snowthrower's specifications to ensure proper fitment.
- Fits 8, 10, and 12 HP snowthrowers.
- Designed for snowthrowers measuring 27-inches to 33-inches.
- Suitable for snowthrowers equipped with a 16-inch diameter auger.
- Replaces Murray part numbers: 313847, 51224P, 322283, and 51224.
3. Installation (Replacement)
Replacing an auger drive belt requires careful attention to safety and proper procedure. Always refer to your specific snowthrower's owner's manual for detailed, model-specific instructions. The following are general steps and safety precautions:
- Safety First: Before beginning any maintenance or replacement, ensure the snowthrower is turned off, the spark plug wire is disconnected to prevent accidental starting, and the engine is cool.
- Access the Belt Area: Depending on your snowthrower model, you may need to remove covers or panels to access the auger drive belt and pulleys.
- Note Belt Routing: Carefully observe or photograph the existing belt's routing around all pulleys and tensioners before removal. This will aid in correct installation of the new belt.
- Relieve Tension: Locate the belt tensioner or idler pulley. You may need to loosen a bolt or lever to relieve tension on the old belt.
- Remove Old Belt: Once tension is relieved, carefully remove the old belt from the pulleys.
- Install New Belt: Route the new Murray 313847MA belt exactly as the old one was installed. Ensure it is seated correctly in all pulley grooves.
- Restore Tension: Re-tension the belt according to your snowthrower's manual. The belt should be snug but not overly tight, allowing for proper engagement and disengagement.
- Reassemble: Replace any covers or panels that were removed.
- Test Operation: Reconnect the spark plug wire. Start the snowthrower and test the auger engagement in a clear area to ensure the belt is functioning correctly.
If you are unsure about any step, it is recommended to consult a qualified service technician.
4. Operation
The auger drive belt facilitates the operation of your snowthrower's auger system. When the auger engagement lever is activated, the belt tightens around the pulleys, transferring power from the engine to spin the auger. This rotation allows the auger to break up and collect snow, which is then propelled out of the discharge chute.
Proper belt tension is critical for efficient operation. A loose belt may slip, reducing auger performance, while an overly tight belt can cause premature wear on the belt and other components.
5. Maintenance
Regular inspection and maintenance of your auger drive belt can extend its lifespan and ensure optimal snowthrower performance.
- Visual Inspection: Periodically inspect the belt for signs of wear, cracking, fraying, glazing, or stretching. Replace the belt if any damage is observed.
- Cleanliness: Keep the belt and pulley areas free from snow, ice, dirt, and debris. Accumulations can cause the belt to slip or wear prematurely.
- Proper Storage: When storing the snowthrower for extended periods, especially during off-season, ensure the belt is not under tension if possible, and store the machine in a dry environment to prevent material degradation.
- Avoid Overloading: Operating the snowthrower beyond its capacity or attempting to clear excessively heavy or frozen snow can put undue stress on the belt, leading to premature failure.
6. Troubleshooting
If your snowthrower's auger is not performing as expected, the drive belt may be a contributing factor. Consider the following common issues:
- Auger Not Turning or Turning Slowly: This often indicates a worn, stretched, or broken auger drive belt. It could also be a sign of incorrect belt tension or an obstruction in the auger housing.
- Squealing Noise During Operation: A squealing sound, especially when the auger is engaged, can suggest a slipping belt. This may be due to insufficient tension, a glazed belt surface, or contamination (e.g., oil, grease) on the belt or pulleys.
- Excessive Vibration: While less common for belts, an improperly installed or severely damaged belt could contribute to unusual vibrations.
Always ensure the snowthrower is off and the spark plug wire is disconnected before inspecting or attempting to resolve any issues related to the belt.
