The Multiquip 6211312410 is a genuine OEM Pin Piston DCA-400SSK SA6D140A1 designed for the DCA400SSK ultra-silent diesel generator. As a certified OEM component, this piston pin is manufactured to the exact tolerances required by the SA6D140A1 engine, ensuring a direct, specification-correct installation with no guesswork. DHS Equipment supplies this part straight from the Multiquip OEM supply chain, so you can be confident you are receiving an authentic replacement for your DCA400SSK unit.
Key Features
- OEM-Spec Dimensional Accuracy — Machined to the precise diameter and hardness specifications of the SA6D140A1 engine, maintaining correct piston-to-pin clearance for proper combustion dynamics.
- Direct Engine Installation — Engineered as a drop-in fit for the SA6D140A1 engine assembly found in the DCA400SSK, matching original bore geometry and pin retainer configuration.
- DCA400SSK Generator Compatibility — Confirmed fitment for the Multiquip DCA400SSK ultra-silent diesel generator series, removing uncertainty during engine rebuild or overhaul.
- Engine Integrity Under Load — A correctly sized piston pin transfers combustion force cleanly from the piston to the connecting rod; a worn or out-of-spec pin causes knock, accelerated bore wear, and loss of power output.
- Genuine OEM Part — Supplied as a Multiquip genuine OEM component, part 6211312410, sourced through authorized distribution channels for full traceability.
The piston pin — also called a wrist pin — is a precision-hardened cylindrical shaft that connects the piston to the small end of the connecting rod inside the engine cylinder. It serves as the pivot point that converts the linear force of combustion into rotational motion at the crankshaft. When a piston pin wears beyond its tolerance, it develops play in the pin bore, producing an audible knock and allowing micro-movement that accelerates damage to the piston, rod bushing, and cylinder wall. Replacing a worn pin with a correctly specced OEM component restores proper mechanical alignment and protects the engine from further internal damage.
