⚠️ Common Signs of Failure

• Bearing rumble or squeal
• Belt edge wear or tracking problems
• Seized bearing causing belt failure
• Heat discolouration or grease leakage

🛠️ Service Notes

• Spin the new pulley by hand before fitting — it should turn smoothly and quietly with no roughness, no drag and no side play
• Inspect the belt-contact face of every pulley in the drive whenever the idler is changed; a grooved, glazed, corroded or chipped face will ruin a new belt quickly
• Renew the belt at the same time, and check the tensioner as well, since these parts wear as a system
• Tighten the mounting fastener to the figure given in the workshop manual for your engine, and confirm the pulley runs true and in line with the rest of the drive
• Check the belt routing and that every rib or groove is properly seated before turning the engine over, then recheck tension after the first running period as the manual directs
