Multiquip M1327200104 Blow-By Hose (JPN) - OEM Replacement Part for Super Silent Generators

The blow-by hose manages crankcase ventilation by routing combustion gases that escape past the piston rings away from the engine, preventing pressure buildup and oil contamination in Multiquip's Super Silent generator series. This genuine Japanese-spec component is critical for maintaining proper engine operation and preventing performance issues in turbocharged, charge air-cooled Isuzu diesel engines.

During routine maintenance, Multiquip service manuals specify that when replacing the blow-by hose, installers must ensure a minimum slope of 1/2 inch per foot with no sags or dips that could collect moisture or oil. Failure to maintain proper drainage can lead to system blockages and increased crankcase pressure. This hose is a wear item subject to heat cycling and should be inspected during regular service intervals, particularly on units operating in demanding environments or under heavy load conditions.

This blow-by hose is confirmed compatible with the following Multiquip generator models:

• DCA36SPXU4F
• DCA45SSIU4F
• DCA45SSIU4FC8
