Part 3923077 Studded Flange Cap Screw Component Usage

The Part 3923077 Studded Flange Cap Screw is an essential component in various engine systems, facilitating secure connections and ensuring the integrity of the assembly. Here’s how it integrates with several key components:

Breather Systems

In breather systems, the studded flange cap screw secures the breather housing to the engine block or crankcase. This connection allows for the release of pressure and contaminants from the crankcase while preventing the ingress of external contaminants.

Crankcase Ventilation

For crankcase ventilation, the screw ensures a tight seal between the crankcase and the ventilation system. This is vital for maintaining proper pressure within the crankcase, which in turn helps in reducing oil contamination and improving engine performance.

Cooler Systems

In engine oil cooler systems, the studded flange cap screw is used to attach the cooler to the engine block or oil lines. This secure attachment is necessary for efficient heat exchange, which helps in maintaining optimal engine oil temperature.

Drain Systems

When it comes to engine oil drain systems, the screw plays a role in securing the drain plug or valve. This ensures that the oil can be efficiently drained from the system without any leaks, which is essential for regular maintenance and oil changes.

Remote Oil Filter Systems

In remote oil filter systems, the studded flange cap screw is utilized to attach the filter housing to the engine. This secure connection is important for maintaining the filter’s efficiency and ensuring that the oil is properly filtered before re-entering the engine.

Fuel Filter Systems

For fuel filter systems, the screw is employed to attach the fuel filter housing to the engine or fuel lines. This ensures a leak-free connection, which is critical for maintaining fuel system integrity and engine performance.

Full Flow Oil Systems

In full flow oil systems, the studded flange cap screw secures the oil filter to the engine block. This connection is vital for ensuring that the oil passes through the filter efficiently, removing contaminants and maintaining oil quality.
