The Multiquip 0191701050 Blow By Hose is a genuine OEM component designed for DCA125USI3CAN and DCA125USI diesel-powered ultra-silent generators. As a direct Multiquip OEM part, it is manufactured to the exact specifications required for proper crankcase ventilation in these units. Sourced direct from the Multiquip parts network, 0191701050 is the correct replacement for worn, cracked, or deteriorated hoses on DCA125USI series equipment.
Key Features
- OEM Material Integrity — Manufactured from hose material rated to handle crankcase blow-by gases and temperatures specific to the Isuzu diesel engine found in DCA125USI series generators.
- Direct Drop-In Replacement — Engineered to match the original routing path and connection points, allowing straightforward installation without fabrication or adaptation.
- Confirmed Fitment — Verified for DCA125USI3CAN and DCA125USI ultra-silent diesel generator models.
- Crankcase Ventilation Performance — A properly functioning blow by hose keeps crankcase pressure balanced; a failed or cracked hose allows oil mist to escape into the engine bay, leading to contamination and potential engine damage.
- Emissions and Engine Health Compliance — Maintaining an intact blow by hose is essential for correct crankcase ventilation, which directly affects engine oil consumption and exhaust emissions on diesel-powered equipment.
The blow by hose routes crankcase blow-by gases — unburned fuel vapors and combustion gases that pass the piston rings — from the engine crankcase back into the intake system or to a designated vent point. This keeps internal engine pressure from building up and prevents oil from being pushed out past seals and gaskets. When the hose cracks, hardens, or disconnects, the crankcase loses its ventilation path, which can cause accelerated oil consumption, increased internal pressure, and contamination of surrounding engine components. Keeping this hose in good condition is a straightforward but important part of routine generator maintenance.
