The Multiquip M2326000104 Blowby Hose is a genuine OEM component designed for DCA-70USJ and DCA85USJ series ultra-silent diesel generators. Sourced directly from Multiquip, this part meets the exact specifications of the original, ensuring a proper fit and consistent performance in the field. It is confirmed compatible with the DCA-70USJ and DCA85USJ generator models, making it a straightforward service replacement for technicians and fleet operators alike. When your generator needs it, ordering the correct OEM part by number eliminates guesswork and keeps your service timeline on track.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional specifications, ensuring the hose handles crankcase blowby gases at the correct pressure and temperature ratings for this engine application.
- Direct-Fit Replacement — Engineered to connect to the existing ports and routing path on the DCA-70USJ and DCA85USJ without any trimming or adapter fittings.
- Confirmed Generator Fitment — Verified for use on DCA-70USJ and DCA85USJ ultra-silent diesel generator models.
- Crankcase Ventilation Integrity — A properly functioning blowby hose routes combustion gases safely away from the engine, preventing oil contamination, rough running, and excess crankcase pressure buildup.
- Emission and Engine Health Compliance — The blowby hose is part of the engine's crankcase ventilation system; using the correct OEM hose helps maintain emissions system function and protects downstream components from unfiltered blowby exposure.
The blowby hose carries combustion gases that escape past the piston rings — known as blowby — from the crankcase back into the engine's air intake or to a ventilation outlet. This controlled routing prevents pressure from building up inside the crankcase, which could otherwise push past gaskets and seals and cause oil leaks. When the hose cracks, collapses, or loses its seal at either connection point, crankcase pressure rises, oil consumption increases, and the engine may begin to run erratically — making prompt replacement critical to keeping the generator running cleanly and efficiently.
