Description

What does a housing oil nozzle do?

This oil nozzle plays a critical role in the engine's lubrication and cooling system by directing pressurized oil toward the piston crown. By spraying oil onto the underside of the piston, it effectively carries heat away from the combustion chamber and into the sump, preventing thermal overload during high-load operation.

Compatible vehicles and engines

This component is compatible with Mercedes-Benz heavy commercial vehicle engines. It is engineered to match the specific spray configuration and connection requirements of the engine block, ensuring optimal pressure management and piston pin lubrication.

Installation and maintenance

Technicians should verify the connection style—whether it is a bolted flange, banjo-connected, or threaded body—to ensure a perfect fit. During installation, inspect the sealing surfaces and ensure that the nozzle is seated correctly within the oil gallery to prevent pressure drops in the main lubrication circuit.

System performance

Maintaining a clean oil gallery is essential for the proper functioning of this part, as any debris can obstruct the spray pattern and lead to excessive piston temperature.

OE cross-reference

0101 029 (Housing Oil Nozzle Crankcase) is the equivalent of the LASO and Mercedes-Benz OE numbers. This part directly replaces LASO OE number 20014313. It also replaces Mercedes-Benz OE numbers 4571801243, 4571801443.
