Introduction

The Cummins 5404708 Crankcase Breather is a component designed to facilitate the proper ventilation of the crankcase in heavy-duty truck engines. Its role is to manage the pressure and contaminants within the crankcase, ensuring the engine operates efficiently and reliably. This breather is integral to maintaining the overall health and performance of the engine.

Basic Concepts of Crankcase Breathers

A crankcase breather is a device that allows air to escape from the crankcase of an engine. As the engine operates, it produces gases and vapors that accumulate in the crankcase. These byproducts, if not properly ventilated, can lead to increased pressure and contamination, which may adversely affect engine performance. The breather facilitates the release of these gases and vapors, maintaining a stable environment within the crankcase ¹.
