Genuine Husqvarna Starter Pulley - 537 20 24-01
The Genuine Husqvarna 537202401 Starter Pulley is the factory-original rope rotor for the large-chassis 70cc+ professional chainsaw family. This high-impact polymer pulley is engineered to handle the high compression of professional engines, ensuring smooth recoil action and reliable starting in demanding conditions.
Designed for High-Compression Saws
Professional saws like the 576 XP put significant stress on the starter assembly. This OEM Husqvarna Pulley is manufactured from a specialized wear-resistant nylon composite that resists groove-notching from the starter rope. Its precise dimensions ensure perfect alignment with the starter spring and pawls, preventing the "slips" and "jams" common with lower-quality aftermarket alternatives.

🛠️ Mechanic's Tip:
When replacing the pulley, apply a very light coat of lithium grease to the center post before installation—this ensures smooth rotation and prevents plastic-on-metal wear. Always pre-tension the recoil spring by turning the pulley two full rotations before threading the rope to ensure the handle retracts fully against the housing.
