Description
Technical Overview & Product Details
Lubrication pipe assemblies are essential for maintaining the health of high-speed gear trains within marine diesel engines. The 746673-39352 is designed to withstand continuous oil pressure and engine vibration, ensuring that the pinion gear receives an uninterrupted supply of lubricant. This precise delivery is fundamental for reducing mechanical friction and extending the operational life of the gear assembly.
- Compatible Engine Type: Yanmar marine propulsion and auxiliary engine series.
- Part Number / Designation: 746673-39352.
- Component Type: Pinion Feed Oil Pipe Assembly.
- Material: High-grade, corrosion-resistant metallic piping with precision-fitted connectors.
- Application: Lubrication supply for pinion gear assemblies.
Key Features & Performance
- Precision Flow Control: Engineered to ensure optimal oil delivery to the pinion gear, maintaining a constant lubrication film to minimize mechanical wear.
- Vibration Resistance: Constructed with materials and fittings capable of enduring the high-frequency vibrations typical of marine diesel engine environments, preventing fatigue or leakage.
- Corrosion Resistance: The piping is treated to resist internal and external corrosion, essential for maintaining system integrity in the presence of engine oil and marine environmental factors.
- Dimensional Integrity: Machined to exact OEM specifications, ensuring a leak-free fitment and easy integration into the engine’s lubrication circuit.

Technical Maintenance Note:
When installing the 746673-39352, it is essential to ensure that all connection points are perfectly clean and free of contaminants to prevent oil line blockages. Inspect the pipe for any signs of internal debris or exterior kinking before installation. Use a torque wrench as specified by the Yanmar service manual to tighten fittings, ensuring a secure, leak-proof connection without over-stressing the pipe threads. During overhaul, it is recommended to inspect the surrounding engine components for any signs of vibration-induced wear that might have contributed to the replacement of the old pipe.
