The Multiquip 6211222220 is a genuine OEM Cylinder Liner DCA-400SSK SA6D140A1 designed for the DCA400SSK ultra-silent diesel generator. As a direct OEM component, this liner is sourced to exact manufacturer specifications, ensuring proper fit within the SA6D140A1 engine assembly. Confirmed fitment for the DCA400SSK series makes this the correct choice when rebuilding or overhauling the engine on this generator. DHS Equipment stocks this part to keep your critical power generation equipment running at full capacity.
Key Features
- Genuine OEM Cylinder Bore Integrity — Manufactured to the exact bore diameter and surface finish specification of the original SA6D140A1 engine, ensuring proper piston-to-wall clearance and compression seal.
- Direct Engine Block Installation — Engineered as a drop-in replacement for the DCA400SSK engine block, matching the original liner's press-fit tolerances for a secure, oil-tight seat.
- Confirmed DCA400SSK Fitment — Verified for use in the DCA400SSK ultra-silent diesel generator equipped with the SA6D140A1 engine; always cross-reference your model and engine serial before ordering.
- Sustains Full Compression and Power Output — A correctly fitted cylinder liner maintains the combustion chamber geometry needed for the SA6D140A1 to deliver its rated power output; a worn or cracked liner leads to blow-by, oil contamination, and loss of generator load capacity.
- Critical Engine Rebuild Component — Replacing the cylinder liner as part of a scheduled overhaul prevents catastrophic engine failure during continuous-duty generator operation, where unplanned downtime carries significant cost.
The cylinder liner is a precision sleeve pressed into the engine block that forms the bore wall within which the piston travels. It provides the hardened, heat-resistant surface needed to withstand the extreme pressures and temperatures of diesel combustion while maintaining a proper seal with the piston rings to preserve compression. When a cylinder liner becomes worn, scored, or cracked, combustion gases escape past the rings, engine oil is consumed, power output drops, and continued operation risks severe internal engine damage that can render the generator unserviceable.
