• Durable Construction: Made to withstand the stresses of snowmobile water pump operations

This belt ensures proper functioning of the water pump, helping to maintain optimal cooling in the engine.

To replace the water pump belt on a Yamaha Vmax 500, Vmax 600, SX500R, or Exciter 570 snowmobile, follow these general steps:

Tools Required:

• Wrenches or socket set
• Screwdriver
• Replacement belt (10mm x 585mm)
• Torque wrench (optional but recommended)

Procedure:

1. Remove Necessary Panels:

   • Begin by removing any side panels or covers that may be obstructing access to the water pump and belt. These panels are typically held in place with screws or clips, which can be removed with a screwdriver or wrench.

2. Locate the Water Pump Belt:

   • The water pump belt is usually located near the bottom of the engine. You may need to loosen or remove a guard or shield to access the belt properly.

3. Release Tension:

   • If there is a tensioner pulley, loosen it to relieve the tension on the water pump belt. This can usually be done with a wrench by turning the tensioner bolt, allowing the old belt to be easily removed.

4. Remove the Old Belt:

   • Carefully slide the old belt off the pulleys. Inspect the belt and pulleys for wear or damage. If the pulleys appear worn, they may need to be replaced as well.

5. Install the New Belt:

   • Place the new belt (10mm x 585mm) onto the pulleys. Ensure the belt is seated properly in the grooves of both the water pump pulley and the crankshaft pulley.

6. Tighten the Belt:

   • Adjust the tensioner pulley (if equipped) to ensure the new belt is tight but not overly so. The belt should have a small amount of play when pressed in the middle (check your service manual for specific tension specs).

7. Reassemble Panels:

   • Once the belt is installed and tensioned, reattach any guards, shields, or panels that were removed during the process.

8. Test the Installation:

   • Start the snowmobile and let it run for a few minutes. Watch the belt to ensure it is running smoothly and is properly aligned with the pulleys.

Additional Tips:

• Check Alignment: Make sure the belt is aligned properly with all pulleys to prevent premature wear.
• Replace Other Components: While replacing the belt, check the condition of the water pump and tensioner pulley. If they are worn, it may be a good time to replace them as well.
• Consult Service Manual: If you have access to the snowmobile’s service manual, refer to it for any model-specific details regarding belt tension or other special considerations.

This is a general procedure, but some steps may vary depending on the exact snowmobile model. For precise instructions, consult the Yamaha service manual for your specific model or reach out to a snowmobile repair specialist.
