DHS Equipment stocks this genuine OEM part so you can get your saw back to cutting without delay.
Key Features
- Factory-Matched Groove Profile: — The 4.0 6G 3VX2012 specification confirms correct groove count and belt-pitch compatibility, ensuring the drive belt seats and tracks properly on the bladeshaft.
- Genuine OEM Construction: — Cast and machined to Multiquip's original engineering tolerances, maintaining the correct balance and concentricity critical for smooth high-speed blade drive operation.
- Confirmed SP Series Fitment: — Verified for use on SP303516, SP303520, SP303526, and SP303530 Multiquip pavement saws — cross-reference your model before ordering.
- Protects Belt and Bearing Life: — A correctly sized and aligned pulley reduces lateral load on the bladeshaft bearings and prevents premature belt wear, keeping drive efficiency where it needs to be.
- Direct Replacement: — Mounts to the existing bladeshaft using the original hardware and interface, matching the OEM part it replaces in every critical dimension.
The bladeshaft pulley is the driven sheave that transfers power from the engine belt drive system to the blade spindle on a pavement saw. It works in conjunction with the V-belt and bladeshaft assembly to spin the cutting blade at the correct speed and torque for asphalt or concrete cutting. When a pulley becomes worn, cracked, or develops groove damage, belt slippage and vibration increase — leading to uneven cuts, accelerated belt failure, and added stress on the bladeshaft bearings. Replacing a damaged pulley promptly with the correct OEM-spec component restores proper power transfer and protects the surrounding drivetrain components.
