4. Setup and Installation
Replacing a pump drive belt requires careful attention to detail. Refer to your mower's specific service manual for the exact procedure. The following are general steps:
- Preparation: Park the mower on a flat, stable surface. Engage the parking brake. Disconnect the spark plug wire and battery. Allow the engine to cool.
- Access the Drive System: Depending on your mower model, you may need to remove deck covers, shields, or other components to gain access to the pump drive belt system.
- Relieve Tension: Locate the tensioning mechanism (e.g., idler pulley) and relieve tension on the old belt. This may involve loosening bolts or using a lever.
- Remove Old Belt: Carefully remove the old pump drive belt from all pulleys. Note its routing path for reference.
- Inspect Pulleys: While the belt is off, inspect all pulleys for wear, damage, or excessive play. Replace any worn components.
- Install New Belt: Route the new Reliable Aftermarket Parts 104334 belt around the pulleys, following the exact path of the old belt. Ensure the belt is seated correctly in all pulley grooves.
- Apply Tension: Re-apply tension to the belt using the tensioning mechanism. Ensure the belt is taut but not overly tight. Refer to your mower's manual for specific tensioning guidelines.
- Reassemble: Reinstall any removed covers or shields.
- Test: Reconnect the spark plug wire and battery. Start the mower and carefully test the drive system at a low speed in a clear area. Listen for unusual noises or vibrations.

5. Operating Considerations
Once installed, the pump drive belt transmits power from the engine to the hydraulic pumps, which in turn power the drive wheels of your zero-turn mower. Proper operation relies on a correctly installed and maintained belt.
- Smooth Engagement: Engage the drive system smoothly to avoid sudden shocks to the belt, which can reduce its lifespan.
- Avoid Overloading: Do not operate the mower beyond its recommended load capacity, as this can strain the drive belt.
- Listen for Changes: Pay attention to any changes in the mower's drive performance, such as slipping, loss of power, or unusual noises, which may indicate belt issues.
6. Maintenance
Regular inspection and maintenance of your pump drive belt are crucial for extending its service life and ensuring reliable mower operation.
- Regular Inspection: Periodically inspect the belt for signs of wear, cracking, fraying, glazing, or stretching. Check for any foreign objects lodged in the pulleys or belt path.
- Cleanliness: Keep the belt and pulleys free from dirt, debris, oil, and grease. Contaminants can cause the belt to slip or wear prematurely.
- Proper Tension: Ensure the belt maintains proper tension as specified in your mower's manual. A belt that is too loose can slip, causing wear and loss of power. A belt that is too tight can put excessive strain on bearings and the belt itself.
- Replacement: Replace the belt if it shows significant signs of wear or damage, even if it hasn't broken. Proactive replacement can prevent unexpected downtime.
