Multiquip 540003 Pulley with Bearing 4" A Section - OEM Replacement Part

This pulley assembly with integrated bearing is a critical power transmission component for Multiquip saws, transferring engine power to the blade drive system through an A-section V-belt. The 4-inch diameter pulley is designed to maintain proper belt tension and alignment while the sealed bearing ensures smooth, friction-free rotation under the demanding conditions of concrete cutting operations.

Pulley wear, bearing failure, or improper belt tracking can lead to reduced cutting performance, excessive vibration, premature belt wear, and potential equipment downtime. Common symptoms of a failing pulley assembly include unusual noise during operation, wobbling or misalignment of the belt, overheating at the pulley location, or difficulty maintaining consistent blade speed. Regular inspection of the pulley for signs of wear, checking bearing play, and monitoring belt condition are essential preventive maintenance practices.

This pulley assembly is compatible with the following Multiquip saw models:

• SP605716
• SP6457
