Engine Pulley
Genuine Mtd part
By: Mtd
Part Number: 756-0241B

The engine pulley is a wheel that guides or drives the belt or belts within the engine compartment. The pulley has groves to help keep the belt secured in place while it spins around the component. The engine pulley belts are typically composed of high-quality, heat-resistant metal materials to withstand high temperatures and long periods of use. At times, the engine pulley can wear out, break, or become otherwise ineffective at performing its function. When this happens, a replacement engine pulley is required.When trying to determine if the engine pulley is faulty, check for belts that continually need to be adjusted or tightened or a pulley that won't secure belts at all. Be sure to have the appropriate tools for the repair on hand. Wear gloves for protection and ensure the motor is completely cooled before starting.This is an engine pulley replacement part that is an authentic OEM piece. It is sourced from the manufacturer and sold as an individual unit. The engine pulley is compatible with various engines found in edgers, trimmers, and snow blowers made by MTD, Yard-Man, Troy-Bilt, Cub Cadet, and Yard Machine brands.
