Multiquip 37570 Pulley 3.7 6 3V 4.5 1 A - OEM Replacement Part

This pulley assembly is a critical power transmission component for Multiquip concrete saws, designed to transfer engine power to the cutting blade system through belt drive operation. The 3.7 6 3V specification indicates a multi-groove V-belt configuration, while the 4.5 1 A designation relates to dimensional and arbor specifications essential for proper fit and alignment.

Pulleys are subject to wear from continuous belt friction, exposure to concrete dust and debris, and the high-stress demands of professional cutting operations. Signs that replacement is needed include excessive belt wear, unusual vibration during operation, difficulty maintaining proper belt tension, or visible damage to the pulley grooves. Using a worn or damaged pulley can lead to reduced cutting performance, premature belt failure, and potential damage to the engine or blade drive components.

This pulley is compatible with the following Multiquip saw models:

• CS403016
• PS403016
• SP403016
