Multiquip 6151351010 Crankshaft Assembly SAA6D125E-5 DCA-300SSK4

The Multiquip 6151351010 is a genuine OEM Crankshaft Assembly designed for the DCA-300SSK4 ultra-silent diesel generator equipped with the SAA6D125E-5 engine. As a direct OEM replacement, this assembly is manufactured to the exact tolerances required by the SAA6D125E-5 powerplant, ensuring correct stroke geometry, bearing journal dimensions, and rotational balance straight out of the box. Sourced directly through Multiquip's authorized parts network, the part is the correct specification part for maintaining the integrity of your DCA-300SSK4 generator. DHS Equipment supplies this component as a stocked OEM part, keeping your critical power generation asset supported with the right hardware.

Key Features

• OEM-Grade Journal Tolerancing — Manufactured to the precise bearing journal dimensions and surface finish specifications of the SAA6D125E-5 engine, ensuring correct oil film formation and load distribution across main and rod bearings.
• Direct-Fit Assembly for SAA6D125E-5 — Engineered as a complete drop-in replacement for the DCA-300SSK4 generator's engine, aligning with all existing mounting points, counterweights, and timing marks without secondary machining.
• Confirmed Fitment — Verified for the Multiquip DCA-300SSK4 ultra-silent generator series powered by the Komatsu SAA6D125E-5 diesel engine.
• Sustained Power Output — A correctly installed crankshaft maintains proper combustion timing and mechanical efficiency, allowing the DCA-300SSK4 to deliver its rated output continuously. A worn or damaged crankshaft causes vibration, bearing failure, and loss of engine power.
• Genuine Multiquip OEM Part — Supplied under Multiquip part number 6151351010, this is an authentic OEM component backed by Multiquip's parts program — not a pattern or aftermarket substitute.

The crankshaft is the central rotating component of a diesel engine, converting the linear force of each piston's power stroke into the rotational torque that drives the generator's alternator. It must maintain precise balance and journal geometry to sustain proper bearing lubrication and combustion timing across thousands of operating hours. When a crankshaft develops wear, cracks, or journal damage, the result is progressive bearing failure, increased engine vibration, loss of oil pressure, and ultimately catastrophic engine seizure — making correct replacement with a properly specified assembly critical to restoring safe and reliable generator operation.
