Installation Guide

1. Safety First: Ensure the engine is off and cool. Disconnect the negative battery cable to prevent accidental starts.
2. Locate the Belt: Identify the alternator and the existing drive belt path around the crankshaft and alternator pulleys.
3. Release Tension: Loosen the alternator's mounting and tensioning bolts. This will allow the alternator to pivot, releasing tension on the belt.
4. Remove Old Belt: Carefully slide the old belt off the pulleys. Take this opportunity to inspect the pulleys for damage or misalignment.
5. Install New Belt: Route the new V-belt around the pulleys, ensuring it is properly seated in the grooves.
6. Apply Tension: Pry the alternator away from the engine to apply tension to the belt. The correct tension typically allows for about 1/2 inch (13 mm) of deflection with firm thumb pressure at the longest span.
7. Tighten Bolts: While maintaining tension, securely tighten the alternator's mounting and tensioning bolts.
8. Final Check: Reconnect the battery cable. Start the engine and listen for any unusual noises. Check that the alternator is charging correctly.

Troubleshooting & FAQ

How do I confirm this belt fits my engine?
Start by checking the 'Compatible Engine Models' table on this page. It is critical to match your engine's model, year, and OEM part number (966906). For models like the MD1B and AQD2B, also confirm the crankshaft pulley diameter as noted in the compatibility chart.

What are common signs my drive belt is failing?
Key indicators of a failing belt include loud squealing noises upon startup or acceleration, visible cracks or fraying on the belt's surface, and a glazed or shiny appearance. A worn belt can slip, leading to poor alternator performance and battery charging issues.

How often should I replace my V-belt?
There is no fixed interval, as lifespan depends on engine hours and operating conditions. We recommend inspecting the belt during every routine service. Replace it immediately if you notice any signs of wear, such as cracking, glazing, or material loss, or as a preventative measure every few years.
