Multiquip 37321 Drive Pulley Assembly 4.1 3V 4.5 1A

The Multiquip 37321 Drive Pulley Assembly 4.1 3V 4.5 1A is a genuine OEM component designed for PS706, SP706, and CS706 series pavement saws. As a direct OEM replacement, part 37321 is manufactured to the same specifications as the original, ensuring proper belt alignment and power transfer to the cutting blade. This assembly is confirmed to fit a wide range of models including PS706016, PS706020, PS706026, PS706030, PS706036, SP706016, SP706020, SP706026, SP706030, SP706036, CS706016, CS706020, CS706026, CS706030, and CS706036.

Key Features

• OEM-Matched Pulley Geometry — Precisely sized at 4.1 3V and 4.5 1A to maintain correct belt tension and groove engagement across all compatible saw models.
• Direct-Fit Installation — Engineered as a drop-in assembly that mounts to the existing drive system without modification to the saw's belt drive configuration.
• Broad Series Coverage — Fits PS706, SP706, and CS706 series pavement saws, covering a large cross-section of Multiquip's flat-cut and pavement saw lineup.
• Sustained Blade Drive Performance — A correctly functioning drive pulley delivers consistent rotational power to the blade; a worn or damaged pulley causes belt slippage, uneven cuts, and accelerated belt wear.
• Genuine OEM Assurance — Sourced directly through Multiquip's OEM supply chain and sold by DHS Equipment, so you receive the exact assembly specified for your machine.

The drive pulley assembly transfers rotational power from the engine's drive system to the saw blade via a belt-and-pulley arrangement. The pulley's groove profile and diameter determine belt tracking, tension, and the final blade speed — all critical factors for clean, accurate cuts in pavement and concrete. When the drive pulley wears, develops groove damage, or loses concentricity, the drive belt begins to slip or shed, leading to reduced blade speed, premature belt failure, and inconsistent cutting depth. Replacing it with the correct OEM assembly restores proper power delivery and protects the rest of the drive train.
