Description
Technical Overview & Product Details
The piston is the primary moving part in the cylinder, subjected to the most intense conditions within the engine. The 146673-22010 is manufactured using advanced materials and precision casting or forging techniques to ensure it can withstand high-compression diesel combustion while maintaining dimensional stability. Its design is critical for managing heat expansion and ensuring a perfect seal against the cylinder liner.
- Compatible Engine Type: Yanmar marine propulsion and auxiliary engine series.
- Part Number / Designation: 146673-22010.
- Component Type: Piston.
- Material: High-strength, heat-resistant alloy designed for superior durability under cyclic combustion stress.
- Application: Primary combustion and reciprocating component within the engine cylinder.
Key Features & Performance
- Exceptional Thermal Resistance: Engineered to maintain structural integrity and dimensions despite the extreme temperatures generated within the combustion chamber.
- Precision Machining: Finished to exact tolerances to ensure the correct clearance between the piston and the cylinder liner, which is vital for minimizing oil consumption and blow-by.
- Optimized Strength-to-Weight Ratio: The piston design balances robust material thickness for durability with optimized mass to reduce inertial forces on the connecting rod and crankshaft.
- Wear Resistance: Features high-quality surfaces and ring-groove hardening to withstand the abrasive forces of operation and the high-frequency cyclic loading of a diesel engine.

Technical Maintenance Note:
When installing the 146673-22010, it is vital to inspect the cylinder liner for proper hone pattern and diameter clearance before fitting. Ensure the piston rings are installed with the correct end-gap as specified by the Yanmar service manual. Always clean the piston and the combustion chamber thoroughly to remove any carbon deposits from previous operation. During installation, use a professional ring compressor to avoid damaging the rings, and apply a light, even coat of clean engine oil to the piston skirt and rings to ensure safe initial startup.
