Description

What does a housing oil nozzle do?

This housing oil nozzle plays a vital role in the engine lubrication system by spraying pressurized oil onto the underside of the piston. By directing oil spray toward the piston skirt, it effectively carries heat away from the combustion chamber, which is essential for maintaining thermal balance in heavy-duty diesel engines.

Engine compatibility and fitment

This component is designed for use in Mercedes-Benz engines. When selecting a replacement, it is important to consider the specific engine code and connection style, as spray tube angles and valve pressure settings must match the original specifications to ensure proper oil delivery to the piston base.

Installation and maintenance

To ensure correct fitment, technicians should verify the connection type—whether it is a bolted flange, banjo-connected, or threaded body—and compare the spray angle with the removed part. Proper installation prevents oil from hitting the cylinder liner and ensures stable gallery pressure during operation.

Troubleshooting and selection

Maintaining these nozzles is crucial for preventing piston overheating and reducing friction at the piston pin. Regular inspection during engine service can prevent potential damage caused by improper oil distribution or pressure drops.

OE cross-reference

0101 030 (Housing Oil Nozzle Crankcase) is the equivalent of the Mercedes-Benz OE number. This part directly replaces Mercedes-Benz OE number A04571801943S.

FAQ

What is the primary function of this oil nozzle?
The nozzle directs pressurized oil onto the underside of the piston to provide cooling and reduce friction at the piston pin, which is critical for engine longevity.
Can I use any oil nozzle for my Mercedes-Benz engine?
No. You must match the specific engine code and connection style (such as banjo or threaded) to ensure the spray angle hits the piston base correctly.
What happens if the wrong nozzle is installed?
An incorrect angle can cause oil to hit the cylinder liner instead of the piston, leading to overheating, loss of gallery pressure, or potential block damage.
How can I identify the correct replacement part?
The most reliable method is to verify the engine code and compare the physical geometry and connection type of the removed part with the new component.
What are the OE reference numbers of this part?
0101 030 directly replaces Mercedes-Benz OE number A04571801943S.
