The Multiquip 37834 Splined Drive Assembly is a genuine OEM component designed for PS403016, PS403020, PS403026, PS403030, SP403016, SP403020, SP403026, SP403030, CS403016, CS403020, CS403026, and CS403030 pavement saws. As a direct OEM replacement, this assembly is manufactured to the exact tolerances required to transfer power cleanly from the drivetrain to the blade, ensuring consistent cutting performance on demanding pavement applications. Sourced directly through Multiquip's authorized parts network, part 37834 is the correct specification for the full PS, SP, and CS 403-series saw lineup. Keep a spare on hand to avoid extended interruptions during active cutting operations.
Key Features
- Genuine OEM Spline Tolerancing — Manufactured to exact spline geometry specifications, ensuring full engagement with mating drivetrain components and eliminating the slippage that worn or undersized drives cause.
- Direct-Fit Assembly — Engineered to drop into PS, SP, and CS 403-series pavement saws without modification, mating directly to the existing drive interface.
- Broad 403-Series Compatibility — Confirmed fitment across PS403016, PS403020, PS403026, PS403030, SP403016, SP403020, SP403026, SP403030, CS403016, CS403020, CS403026, and CS403030 models.
- Sustained Blade Power Transfer — A correctly functioning splined drive delivers uninterrupted torque to the blade; a worn assembly causes blade flutter, uneven cuts, and accelerated wear on surrounding components.
- Heavy-Duty Construction — Built to withstand the continuous rotational load and vibration demands of 30 HP diesel-powered pavement sawing through asphalt and concrete.
The splined drive assembly is the mechanical link between the saw's power source and its blade shaft, transmitting rotational torque through interlocking splines machined into both the drive and driven components. When the assembly is in good condition, power transfer is smooth and consistent, allowing the blade to cut at the correct speed and depth. As splines wear, the connection loosens, causing slippage, vibration, and inconsistent blade speed — ultimately reducing cut quality and placing additional stress on the engine, blade arbor, and adjacent drive components. Replacing a worn 37834 assembly promptly restores full drivetrain integrity and protects the surrounding components from accelerated wear.
