⚠️ Common Signs of Failure

  • Belt squeal or repeated belt dust
  • Worn or chipped pulley grooves
  • Pulley wobble or run-out
  • Cracks around the hub
  • Repeated belt misalignment

🛠️ Service Notes

  • Inspect the belt running surfaces before fitting — a pulley with glazed, scored, pitted or rust-roughened grooves will chew through a new belt in very little running time
  • Check that the pulley runs true and that its bearing or bush turns smoothly with no roughness or side play; fit a new belt whenever a pulley is changed
  • Confirm that every pulley in the drive lies in the same plane and that the belt profile matches each groove — misalignment shows up as belt dust, squeal or a worn belt edge and will destroy a new belt quickly
  • Fit onto a clean, dry, burr-free shaft or hub face and tighten the retaining fasteners in the sequence and to the figures given in the workshop manual for your engine
  • Turn the engine over by hand before starting to confirm the belt is fully seated in every groove and that nothing fouls, then recheck belt tension after the first running period
