The Multiquip 6212721860 is a genuine OEM Injection Pump SA6D140E DCA400SSK designed for the DCA400SSK ultra-silent diesel generator. As a direct OEM replacement, this fuel injection pump is sourced to the original specification, ensuring the SA6D140E engine receives the precise fuel delivery it requires to maintain rated output and stable load performance. DHS Equipment stocks this part for contractors and fleet operators who depend on the DCA400SSK for critical power applications where unplanned downtime is not an option.
Key Features
- OEM Fuel Delivery Precision — Built to the exact injection timing and pressure specification of the SA6D140E engine, ensuring consistent combustion and rated generator output.
- Direct OEM Replacement — Mounts and connects to the SA6D140E fuel system using the original attachment points, requiring no modification to fuel lines or mounting hardware.
- Confirmed Fitment for DCA400SSK — Engineered specifically for the Multiquip DCA400SSK ultra-silent diesel generator series.
- Sustained Load Stability — A correctly functioning injection pump maintains even fuel distribution across all cylinders, supporting stable voltage and frequency output under varying electrical loads.
- Fuel System Integrity — Proper injection pump function is critical to preventing unmetered fuel delivery, which can cause hard starting, excessive smoke, or engine damage over time.
The fuel injection pump is the heart of the diesel fuel system — it pressurizes and meters fuel from the tank and delivers precisely timed, high-pressure charges to each engine cylinder. On the SA6D140E engine used in the DCA400SSK generator, this pump is responsible for maintaining the fuel delivery accuracy that keeps the generator running at stable voltage and frequency under load. When an injection pump wears or fails, symptoms typically include hard starting, rough running, loss of power, excessive black or white exhaust smoke, and ultimately the inability to sustain load — making prompt replacement with the correct OEM part essential to restoring full generator performance.
