55014309 LASO Housing Oil Nozzle Equivalent

What does a housing oil nozzle do?

The housing oil nozzle plays a critical role in the engine's lubrication and cooling system. By directing a controlled spray of oil onto the underside of the piston, this component helps dissipate heat from the combustion chamber and provides essential lubrication to the piston pin and connecting rod bushings. This process is vital for maintaining thermal balance and preventing premature component wear in heavy-duty diesel engines.

Compatibility and engine fitment

This specific housing oil nozzle is compatible with LASO systems and various heavy commercial vehicle engines. For accurate fitment, it is essential to match the component to the specific engine code and cylinder position, as spray tube angles and connection styles vary significantly between different engine families.

Installation and maintenance

When replacing this component, technicians should verify the connection type—whether it is a bolted flange, banjo-connected, or threaded body—to ensure a secure seal. Proper installation ensures that oil pressure is maintained at the correct threshold, preventing drops in gallery pressure during idle or high-load operation. Consult your authorized distributor to confirm exact compatibility.

Selection guidance

Selecting the correct nozzle based on engine specifications prevents issues such as oil hitting the cylinder liner instead of the piston base. Always verify the spray geometry and valve opening pressure requirements to maintain optimal engine performance.
