The Multiquip 6212312170 is a genuine OEM Piston DCA-400SSK SA6 DNS designed for the DCA400SSK ultra-silent diesel generator series. Sourced directly from Multiquip, this piston is manufactured to exact engine specifications, ensuring a correct, reliable fit within the SA6 engine assembly. DCA400SSK operators can count on this part to restore full engine displacement and compression integrity. DHS Equipment stocks genuine Multiquip components so you can get your generator back on the job without compromise.
Key Features
- Genuine OEM Engine Specification — Machined to the exact bore diameter, crown profile, and ring groove tolerances required by the SA6 diesel engine, ensuring proper compression sealing from the first start.
- Direct Engine Replacement — Engineered to drop into the SA6 cylinder bore of the DCA400SSK, aligning with the connecting rod and ring set without secondary machining or shimming.
- Confirmed DCA400SSK Fitment — Verified for the Multiquip DCA400SSK ultra-silent diesel generator; always match your model code before ordering.
- Restores Full Power Output — A worn or scored piston causes loss of compression, increased oil consumption, and reduced generator output; this genuine replacement brings combustion efficiency back to spec.
- Combustion Integrity and Engine Safety — A correctly fitted piston prevents blow-by gases from contaminating the oil system, protecting bearings and downstream engine components from accelerated wear.
The piston is the primary reciprocating component inside the engine cylinder, converting the force of combustion into rotational power through the connecting rod and crankshaft. In a diesel generator like the DCA400SSK, maintaining correct piston-to-wall clearance and ring seal is critical to sustaining stable voltage output and fuel efficiency under load. When a piston wears, cracks, or scores, compression drops, oil consumption rises, and the engine may misfire or fail to carry rated load — replacing it with a genuine OEM part like the Multiquip 6212312170 restores the combustion cycle to its original design parameters.
