Multiquip 37002 Pulley Pump Drive 3.75" A-Section - OEM Replacement Part

This 3.75" A-section pump drive pulley is a critical power transmission component in Multiquip concrete saw fuel and hydraulic systems. The pulley transfers rotational power from the engine to the fuel transfer pump, ensuring consistent fuel delivery from the 8-gallon fuel tank through the primer system to the engine. Without proper pulley function, fuel delivery will fail, preventing engine operation or causing stalling under load.

This precision-manufactured pulley is designed to maintain proper belt tension and alignment in demanding concrete cutting applications. Symptoms of pulley wear include squealing belts, fuel delivery inconsistencies, difficulty priming after refueling, or visible wobble during operation. Regular inspection of the pulley for wear, cracks, or groove damage should be part of routine maintenance intervals, particularly in high-hour commercial cutting operations.
