Inspect the pulley if the belt drive shows symptoms such as:

• Pulley bearing noise

• Excessive pulley wobble

• Belt tracking problems

• Rough pulley rotation

• Visible pulley damage

• Belt repeatedly coming off

• Excessive belt wear near the idler

These symptoms can also be caused by other belt-drive components, so inspect the complete system before replacing parts.

Before purchasing, verify:

• Equipment model number

• Attachment model number

• Serial number when applicable

• Existing pulley part number

• Parts diagram for your specific equipment

The correct identification should show 756-3005 for the pulley location being serviced.
