Description

What does a housing oil nozzle do?

This housing oil nozzle plays a critical role in the engine lubrication system by directing oil spray toward the underside of the piston. By managing oil flow through a spring-loaded check valve, it ensures that heat accumulated in the piston crown is effectively carried away into the sump, maintaining thermal balance during high-load operation.

Compatible vehicles and engines

This component is designed for compatibility with MAN engines. It functions within the crankcase to provide essential piston cooling and lubrication for the piston pin and connecting rod small-end bushing. Proper operation helps prevent piston ring sticking and ensures long-term engine reliability under heavy-duty commercial vehicle service.

Installation and maintenance

Installation requires precise attention to torque specifications and mounting type, whether it is a bolted flange or a threaded body design. Technicians should verify the engine code and cylinder position to ensure exact spray geometry. Consult your authorized distributor to confirm fitment for your specific engine family.

Troubleshooting and selection

Monitoring oil pressure and checking for spray pattern consistency during maintenance can prevent overheating issues in turbocharged engines.

OE cross-reference

0102 031 (Housing Oil Nozzle Crankcase) is the equivalent of the MAN OE number. This part directly replaces MAN OE number 51016015066.

FAQ

What is the primary function of this housing oil nozzle?
The nozzle directs pressurized oil onto the underside of the piston to dissipate heat and lubricate the piston pin, which is vital for preventing thermal damage.
How does this part ensure engine longevity?
By providing consistent cooling to the piston crown, it helps maintain thermal balance and prevents issues like piston ring sticking in heavy-duty engines.
Can I select this part based solely on vehicle make?
No, selection must be based on the specific engine code and cylinder position to ensure the spray geometry matches the requirements of the block.
What should be checked during installation?
Technicians should verify the mounting type—such as bolted flange or threaded body—and adhere to the manufacturer's tightening torque specifications.
What are the OE reference numbers of this part?
0102 031 directly replaces MAN OE number 51016015066.
