The Multiquip 540065 is a genuine OEM 4.2 6G 3V 2012 Taper Pulley designed for SP, PS, and CS series pavement saws. This is a direct OEM replacement sourced through Multiquip's authorized parts program, ensuring the correct taper bore dimensions, groove profile, and belt engagement geometry for your saw. Confirmed fitment covers a wide range of models including SP303516, SP303520, SP303526, SP303530, PS403016, PS403020, PS403026, PS403030, PS403030, SP403016, SP403020, SP403026, SP403030, CS403016, CS403020, CS403026, and CS403030. When replacing a worn or damaged drive pulley, using the correct OEM part keeps belt alignment true and blade drive performance consistent.
Key Features
- Genuine OEM Taper Bore Specification — Manufactured to exact taper lock dimensions, ensuring proper seating on the shaft and consistent torque transfer without slippage.
- Correct 3-Groove Belt Profile — The 3V triple-groove configuration matches the OEM belt arrangement, maintaining full drive power to the blade without belt wear from mismatched sheave geometry.
- Broad Pavement Saw Compatibility — Fits SP303, SP403, PS403, and CS403 series pavement saws, covering both Street Pro and Stow flat saw platforms in the Multiquip lineup.
- Drive System Integrity — A correctly sized pulley maintains proper belt tension and speed ratio; a worn or undersized pulley causes belt slipping, overheating, and reduced blade RPM under load.
- Drop-In OEM Replacement — The 2012 taper bushing interface aligns with the factory shaft and keyway, allowing straightforward swap-out during scheduled drive system service.
The drive pulley on a pavement saw transfers engine power through the belt system to spin the blade at the correct cutting speed. On 3V groove configurations, the pulley must match the belt profile precisely — any mismatch in groove angle or diameter throws off belt tension, causes uneven wear, and reduces cutting force under load. A worn or cracked taper pulley can also loosen on the shaft under vibration, leading to sudden loss of blade drive. Replacing the pulley with the correct OEM part, Multiquip 540065, restores the full mechanical drive path and protects downstream belt and blade components from accelerated wear.
