How do these pulleys match my mower’s original parts?

Each pulley is manufactured to match the original outer diameter (OD), inner diameter (ID), and hub height of the referenced OEM part numbers so belts retain correct alignment and tension. POSFLAG lists direct replacement numbers for Husqvarna, Craftsman, Oregon and other brands to help you confirm fit.

What hardware is included and will I need extra tools?

How durable are these pulleys and what maintenance do they need?

• Double-sealed bearing arrives pre-lubricated to limit immediate maintenance.
• Robust construction designed for typical residential and light commercial mowing loads.
• Inspect belts and pulleys seasonally; replace if you find excessive wear, cracks, or wobble.
