The Multiquip Y0602044509 Blow-By Filter Cover Upper is a genuine OEM component designed for the DCA Super-Silent Generator series, including the DCA150SSJU4F3 and DCA180SSJU4F3 models. As a factory-sourced part, it meets the exact material and dimensional specifications of the original, ensuring a correct fit within the engine's crankcase ventilation system. Verified fitment covers both 60Hz-rated configurations of these Super-Silent generators, making it straightforward to confirm compatibility before ordering.
Key Features
- Genuine OEM Construction — Manufactured to the original dimensional and material tolerances required for a properly sealed blow-by filter housing — no compromise on cover integrity or fit.
- Direct-Fit Replacement — Engineered to seat and secure exactly as the factory-installed cover, aligning correctly with the lower housing assembly without rework or adaptation.
- Confirmed Generator Series Fitment — Compatible with DCA150SSJU4F3 and DCA180SSJU4F3 Super-Silent Generator models, including 60Hz-rated variants.
- Crankcase Ventilation Protection — Maintains the integrity of the blow-by filter enclosure, keeping the ventilation path free from contamination and the engine oil system functioning as designed.
- Fuel and Emission System Compliance — A correctly sealed blow-by cover supports proper crankcase pressure management, which is directly tied to emissions performance on Tier 4 Final-compliant generator equipment.
The blow-by filter cover houses and protects the crankcase ventilation filter, which captures oil mist and combustion gases that pass by the piston rings during normal engine operation. By sealing this system correctly, the cover ensures those gases are routed back into the intake rather than vented to atmosphere, protecting both engine components and emissions compliance. When the cover is cracked, warped, or missing, the ventilation system loses its seal — leading to oil contamination, elevated crankcase pressure, and potential emissions issues on Tier 4 Final engines like those found in the DCA Super-Silent series.
