The Multiquip Y0191700480 Blowby Hose is a genuine OEM component designed for the DCA220SSJU4F super-silent diesel generator series. Sourced directly from Multiquip, this replacement hose meets the exact specifications of the original part installed at the factory. It is engineered for the DCA220SSJU4F platform, including both the standard and 60Hz diesel-powered configurations. When it comes time to restore your generator's crankcase ventilation system to proper working order, the Y0191700480 is the correct OEM solution.
Key Features
- Genuine OEM Construction — Manufactured to the same material and dimensional standards as the original hose, ensuring correct sealing, flexibility, and compatibility with the crankcase ventilation system.
- Direct-Fit Replacement — Designed to connect to the existing ports and routing path on the DCA220SSJU4F without any modification to hose routing or fittings.
- Confirmed Fitment for DCA220SSJU4F — Compatible with both the standard DCA220SSJU4F and the 60Hz diesel-powered generator variants in the super-silent series.
- Maintains Proper Crankcase Ventilation — A correctly functioning blowby hose channels crankcase gases safely away from the engine, preventing pressure buildup and protecting seals and gaskets from premature failure.
- Prevents Oil Contamination and Emissions Issues — A cracked or deteriorated blowby hose can allow unmetered gases to escape, leading to oil misting, fouled air intake components, and elevated emissions — replacing it promptly keeps the engine running clean.
The blowby hose is part of the engine's crankcase ventilation system, responsible for routing combustion gases that bypass the piston rings — known as blowby gases — away from the crankcase and back into the intake or to a safe vent point. This prevents excess pressure from building up inside the engine, which can force oil past seals and gaskets and cause leaks. When the hose cracks, hardens, or collapses due to heat and age, the ventilation system loses its ability to manage crankcase pressure effectively, often resulting in oil consumption, rough running, and accelerated wear on internal engine components.
