BREATHER,CRANKCASE
Cummins®

The BREATHER,CRANKCASE part, identified by the part number 3636916 and manufactured by Cummins, is a component designed for the crankcase ventilation system of commercial trucks. This part facilitates the removal of blow-by gases from the crankcase, helping to maintain optimal pressure and cleanliness within the engine compartment.

Basic Concepts of Crankcase Ventilation

The crankcase ventilation system is responsible for managing the gases that escape past the piston rings into the crankcase. These gases, known as blow-by, contain unburned fuel, combustion byproducts, and moisture. The crankcase breather plays a role in venting these gases while preventing contaminants from entering the crankcase. Maintaining proper pressure within the crankcase is important for engine efficiency and longevity ¹.

Function and Operation of the BREATHER,CRANKCASE

The BREATHER,CRANKCASE part #3636916 operates by allowing the flow of blow-by gases out of the crankcase while filtering out dirt, dust, and other contaminants. This dual-action helps keep the crankcase clean and prevents pressure build-up, which could lead to oil leaks or reduced engine performance. The breather ensures that the gases are safely vented to the atmosphere or recirculated back into the intake system, depending on the truck’s design ².

Purpose and Role in Truck Operation

The BREATHER,CRANKCASE part #3636916 contributes to the operation of commercial trucks by ensuring that the crankcase remains free of excess pressure and contaminants. This part supports engine performance by maintaining a clean environment for the moving parts within the crankcase. It also plays a role in emissions control by managing the release of blow-by gases, which can contain harmful pollutants.

Key Features

The BREATHER,CRANKCASE part #3636916 is designed with several features that enhance its performance and durability. It is constructed from high-quality materials to withstand the harsh conditions within the engine compartment. The design includes filtration elements that effectively trap contaminants, ensuring that only clean air enters the crankcase. Additionally, the part is engineered to fit precisely within the truck’s ventilation system, ensuring compatibility and efficient operation.

Benefits

Using the BREATHER,CRANKCASE part #3636916 offers several benefits. It contributes to improved engine efficiency by maintaining optimal crankcase pressure and cleanliness. The part also plays a role in reducing emissions by managing the release of blow-by gases. Furthermore, it enhances the reliability of the truck’s engine by preventing contamination and pressure-related issues, leading to longer engine life and reduced maintenance costs.

Troubleshooting and Maintenance

Common issues with the BREATHER,CRANKCASE part #3636916 may include clogging of the filtration elements or damage to the breather housing. Symptoms of failure can manifest as oil leaks, reduced engine performance, or increased emissions. Diagnostic procedures involve inspecting the breather for signs of damage or contamination and testing the crankcase pressure. Recommended maintenance practices include regular inspection and cleaning of the breather, as well as replacement according to the manufacturer’s guidelines to ensure optimal performance and longevity.
