Failure Symptoms

A worn or damaged pulley may initially produce a high-pitched squealing or grinding noise, particularly when the associated system is engaged. If left unaddressed, the pulley's imbalance or damaged surface can cause excessive vibration and premature wear on the drive belt, potentially leading to belt failure. Continued operation risks damage to the shaft it is mounted on or the driven component.

Installation Tip

Ensure the shaft is clean and free of any burrs or damage before mounting the new pulley to guarantee proper seating. Avoid hammering the pulley onto the shaft; use appropriate press or puller tools to avoid damaging the pulley or shaft.

Service Note

Inspect the drive belt for wear and proper tension, and check the driven component for smooth operation when replacing the pulley.
