Expert Maintenance Review

Inspect idler pulleys whenever servicing or replacing V-belts. Check the pulley face for wear, cracking or damage and rotate the pulley by hand to identify roughness, excessive bearing movement or noise.

Also inspect the associated idler arm, mounting bolt, tensioning components and belt condition. A damaged or seized pulley can quickly shorten the service life of a new belt.

Installation Tip

Before fitting the replacement pulley, inspect the mounting point and tensioning mechanism for wear or damage. Confirm the pulley is correctly aligned with the adjoining drive pulleys and that the V-belt is tensioned according to the machine manufacturer's service procedure.
