Overview – UREA SUPPLY MODULE E5505779
The Cummins UREA SUPPLY MODULE E5505779 is specified for Cummins aftertreatment positions as the urea (DEF) supply module and is supplied to the original dimensional and material standard.
Parts Characteristics
A urea supply module that stores, pumps and doses the diesel exhaust fluid into the aftertreatment stream, carrying the reagent that completes the reduction. It carries the fluid under demand, so a true, sealed module keeps the emissions stage working and the engine out of derate.
Applicable Models & Applications
Used on Cummins aftertreatment routes specifying this urea supply module. Match the module to the aftertreatment family and the dosing spec – urea modules differ by platform and calibration.
Maintenance & Replacement
Inspect for a leaking joint and a frozen line in cold weather at every aftertreatment service. A module that has begun to leak delivers raw exhaust, and the leak is what trips the fault code.
Confirm the dosing and the supply are correct on fit. A module reversed or starved doses nothing and the system runs cold.
Keep the correct urea supply module for your engine family available. It is load-critical, and an engine stopped on aftertreatment is an engine waiting on a large part.
Source to the specification to avoid a derate. A urea module that cannot hold pressure leaves the engine in reduced power.
