Installation Guide
- Preparation: Ensure the engine is cool. Disconnect the battery to prevent accidental starter engagement.
- Tensioner Adjustment: Locate the belt tensioner pulley. Use a wrench or torque tool to release tension, allowing the belt to slide onto the pulleys.
- Belt Placement: Route the belt around each pulley in the correct sequence (alternating direction for V‑ribbed belts). Verify that the belt sits snugly on all pulleys without overlapping.
- Tensioning: Reapply tension by tightening the tensioner until the belt is firmly seated. Check that the belt does not sag or bind.
- Final Inspection: Inspect for proper alignment, ensure no gaps between ribs and pulleys, and confirm that the belt is free of kinks.
Maintenance Tips
- Inspect the belt every 10,000 km or annually for cracks, fraying, and wear.
- Check tension regularly; a properly tensioned belt should not sag more than 5 mm at its midpoint.
- Avoid exposure to oil leaks or excessive heat sources that could degrade the material.
- Replace the belt if any signs of deterioration appear, even if mileage is below typical replacement intervals.
