A0001400368 Mercedes-Benz Compatible Housing Oil Nozzle

What does a housing oil nozzle do?

This engine component plays a vital role in maintaining the thermal balance and lubrication of heavy commercial vehicle engines. By spraying pressurized oil directly onto the underside of the piston, it effectively carries heat away from the combustion chamber and into the sump. This process is essential for preventing excessive heat accumulation and ensuring long-term engine reliability.

Engine compatibility and function

This specific nozzle is compatible with Mercedes-Benz engines. In heavy-duty diesel applications, these components are critical for piston cooling and reducing friction at the piston pin and connecting rod small-end bushing. Ensuring the correct spray configuration is essential to prevent oil from hitting the cylinder liner walls instead of the piston base.

Installation and maintenance guidance

When performing maintenance or replacement, technicians should verify the connection style—whether it be a bolted flange, banjo connection, or threaded body—to ensure a proper seal. It is highly recommended to match the spray tube angle and check valve opening pressure with the original part to maintain correct gallery pressure during all engine operating speeds.

Selection and troubleshooting

For precise fitment, always cross-reference the part with the existing component or engine code to avoid geometry mismatches that could lead to block damage or oil leakage.

OE cross-reference

0101 035 (Housing Oil Nozzle Crankcase) is the equivalent of the Mercedes-Benz OE number. This part directly replaces Mercedes-Benz OE number A0001400368.
