8TEN Flat Idler Pulley

This pulley is designed as a direct OEM replacement for specific Husqvarna, Jonsered, and Poulan models. Before purchasing, verify your mower's original part number against the manufacturer's specifications to ensure the 3.48-inch outer diameter and 0.39-inch bore match your current setup.

Nylon 6 (PA) is an excellent material for idler pulleys because it is lightweight, resistant to corrosion, and provides smooth operation without the risk of rusting. It is engineered to withstand the heat and friction typical of standard lawn mower drive systems, offering a reliable, long-lasting alternative to metal components.

You should consider replacing your pulley if you notice squealing or grinding noises while the mower is running, or if the belt frequently slips or jumps off. Inspect the pulley for visible cracks, flat spots on the outer edge, or excessive wobble in the bearing, as these indicate the part is failing and affecting belt tension.

If you are comfortable with basic mechanical maintenance, this is a straightforward DIY repair. You will typically need standard hand tools to remove the belt tension, unbolt the old pulley, and secure the new one in place, but always consult your mower's service manual for specific safety instructions.

This product includes the pulley itself. It is designed to reuse your existing mounting hardware, such as the bolt and spacers, so be sure to keep those components organized when you remove the old pulley.
