The Multiquip 37002 Pump Drive Pulley 3.75" A-Section is a genuine OEM component designed for PS, SP, and CS series pavement saws, including models PS403016, PS403020, PS403030, PS706016, PS706020, SP403020. As an authorized Multiquip OEM part, 37002 is manufactured to the same specifications as the original, ensuring a correct installation without guesswork. This pulley is an essential drive-train component that keeps the water pump system operating properly during concrete cutting operations. If you're servicing a PS, SP, or CS series saw, confirming your model against the fitment list below before ordering is always recommended.
Key Features
- Genuine OEM Construction — Manufactured to original design tolerances for consistent belt engagement and load transfer across A-section drive configurations.
- Correct A-Section Belt Profile — The 3.75" A-section groove profile accepts standard A-section V-belts directly, ensuring proper belt seating and tension without shimming or adaptation.
- Broad Pavement Saw Compatibility — Fits an extensive range of PS, SP, and CS series Multiquip pavement saws, covering both 403 and 706 platform configurations.
- Maintains Water Pump Drive Efficiency — A worn or cracked pump drive pulley causes belt slippage and reduced water flow to the blade, risking blade overheating and premature wear during cutting.
- Direct OEM Part Number Cross-Reference — Part number 37002 maps directly to the original Multiquip specification, making verification straightforward when ordering from service records or parts manuals.
The pump drive pulley transfers rotational power from the engine's belt drive system to the water pump on pavement and concrete saws. On these machines, a continuous water supply to the cutting blade is critical — it cools the diamond blade, suppresses silica dust, and extends blade life significantly. When the pump drive pulley wears, develops cracks, or the groove profile becomes rounded, belt traction is lost, water flow drops, and the blade runs dry. Replacing a damaged pulley promptly with the correct OEM part restores full pump output and protects both the blade and the operator.
