A5411800743 Mercedes-Benz compatible Housing Oil Nozzle

What does a housing oil nozzle do?

This engine component plays a vital role in the lubrication and cooling system of heavy commercial vehicle engines. By directing pressurized oil from the main gallery toward the underside of the piston, it helps dissipate heat from the combustion chamber and provides lubrication to the piston pin and connecting rod small-end bushing.

Engine compatibility and fitment

This specific part is designed for compatibility with Mercedes-Benz engines. When replacing this component, it is essential to match the exact geometry and spray configuration required by the specific engine code to ensure optimal oil flow and prevent improper lubrication.

Installation and maintenance guidance

To ensure correct installation, technicians should verify the connection style—whether it be a bolted flange, banjo connection, or threaded body—and confirm that the spray tube angle matches the original specification. Proper seating in the engine block gallery is critical to prevent pressure drops or oil leakage during operation.

Selection and troubleshooting

Correct selection prevents issues such as oil hitting the cylinder liner instead of the piston base. For precise fitment, always refer to the engine code and technical specifications provided by the manufacturer.
