The Multiquip 71431021740 Crankshaft Assembly is a genuine OEM component designed for the MVH-406DSY reversible plate compactor and the MRH800DS2 walk-behind roller. Sourced directly from Multiquip, this assembly meets the same specifications as the original part installed at the factory, ensuring a correct, direct installation with no guesswork. Confirmed fitment for MVH-406DSY and MRH800DS2 equipment makes the 71431021740 a dependable choice when rebuilding or overhauling the bottom end of these machines.
Key Features
- Genuine OEM Crankshaft Integrity — Manufactured to Multiquip's original tolerances for journal diameter, stroke, and balance, maintaining the precise rotating dynamics the engine was designed around.
- Direct-Fit Replacement — Engineered to drop into the existing engine block with matching bearing journals, keyways, and taper dimensions — no machining or adapting required.
- Confirmed Fitment — Compatible with the MVH-406DSY heavy-duty reversible plate compactor and the MRH800DS2 walk-behind roller, covering two core Multiquip compaction product families.
- Restored Power Transfer — A correctly functioning crankshaft converts combustion energy into the rotational force that drives compaction output; a worn or cracked crank causes vibration, loss of power, and accelerated bearing failure.
- Complete Assembly — Supplied as a full crankshaft assembly, reducing the number of individual components needed for a bottom-end rebuild and simplifying the service process.
The crankshaft assembly is the central rotating component inside the engine, converting the linear force of each piston stroke into the rotational motion that powers the machine's drive and vibration systems. In compaction and roller equipment, crankshaft condition is critical — any wear to the bearing journals, cracks in the shaft, or loss of rotational balance will introduce engine vibration, excessive wear on connecting rod bearings, and ultimately engine failure. Replacing a damaged or worn crankshaft with a genuine OEM assembly restores the engine to its original operating condition and protects surrounding components from further damage.
