The Multiquip 5117400211 Air Breather Assembly is a genuine OEM component designed for DCA25SSIU, DCA25SSAI, DCA25SSI, DCA25SSI2, and DCA25SSIU-GEER ultra-silent diesel generator models. Sourced directly from Multiquip, this assembly matches the exact specification of the original part installed at the factory. It is a direct fitment replacement for the DCA25SS series, ensuring the engine crankcase ventilation system continues to perform exactly as intended. DHS Equipment stocks this part to keep your generator running at full capacity with no guesswork on compatibility.
Key Features
- Genuine OEM Construction — Manufactured to the same material and dimensional tolerances as the original breather assembly, ensuring correct venting pressure and crankcase protection specific to this engine configuration.
- Direct-Fit for DCA25SS Series — Engineered specifically for DCA25SSIU, DCA25SSAI, DCA25SSI, DCA25SSI2, and DCA25SSIU-GEER generators, connecting to existing mounting points without modification.
- Crankcase Pressure Control — Maintains proper crankcase pressure balance so the engine operates cleanly and efficiently, preventing oil contamination and excess blowby buildup.
- Protects Engine Seals and Gaskets — A functioning breather assembly prevents excessive internal pressure that would otherwise force oil past seals and gaskets, protecting the broader engine from costly damage.
- Verified Multiquip Part Number — Listed under part number 5117400211, matching Multiquip's official parts catalog for the DCA25SS generator family for confident ordering.
The air breather assembly manages crankcase ventilation by allowing built-up gases and pressure inside the engine to vent safely while preventing outside contaminants from entering the crankcase. In a diesel generator like the DCA25SS series, proper crankcase breathing is essential to maintaining clean oil, protecting internal engine components, and sustaining consistent power output. When the breather assembly becomes clogged or fails, pressure builds inside the engine, accelerating wear on seals, gaskets, and piston rings, and can lead to oil leaks or engine damage if left unaddressed.
