Description

Technical Overview & Product Details

Cylinder liners are the primary wear surfaces within an engine block. The 146673-01150 is manufactured to manage the high-frequency reciprocating movement of the piston and the abrasive action of the piston rings. Designed for consistent wall thickness and superior material hardness, this liner ensures a robust seal that maximizes power output and fuel efficiency during long-term maritime operations.

  • Compatible Engine Type: Yanmar marine propulsion and auxiliary engine series.
  • Part Number / Designation: 146673-01150.
  • Component Type: Cylinder Liner (Cylinder Sleeve).
  • Material: High-grade, wear-resistant cast iron or alloy steel, processed for optimized surface finish and lubrication retention.
  • Application: Engine block cylinder bore housing.

Key Features & Performance

  • Exceptional Wear Resistance: Engineered with specialized metallurgical properties to resist abrasive wear and scuffing, which is critical for maintaining performance over extended maintenance intervals.
  • Thermal Conductivity: Optimized material composition ensures efficient heat dissipation from the combustion chamber to the engine cooling system, preventing localized overheating.
  • Precision Dimensional Tolerance: Machined to exact internal and external diameters to ensure a perfect fit within the engine block, preventing coolant leakage and ensuring stable cylinder pressure.
  • Surface Geometry: The internal bore surface is finished to precise roughness standards, which promotes effective oil film retention and proper “seating” of the piston rings.

Why Source from Heybeli Marine?

A worn or damaged cylinder liner can lead to severe power loss, high oil consumption, and potential piston seizure. Heybeli Marine protects your vessel’s performance with:

  • Strict OEM Interchangeability: Our 146673-01150 liners are manufactured to meet the exact dimensional and hardness specifications required for Yanmar engines.
  • Global Strategic Logistics: We maintain a ready-to-ship inventory of these critical internal components, ensuring they reach your vessel or shipyard quickly to avoid costly maintenance delays.
  • Quality Assurance: Every batch undergoes rigorous inspection, including wall thickness verification and surface finish analysis, to ensure durability under heavy-duty maritime conditions.
  • Complete Overhaul Support: We provide these liners alongside pistons, rings, and seals to help you conduct a professional, total top-end rebuild.

Technical Maintenance Note:

When installing the 146673-01150, it is critical to ensure the engine block bore is perfectly clean, free of debris, and inspected for any signs of pitting or corrosion. Always verify the liner protrusion (if applicable) and ensure correct orientation if the design includes specific cooling or lubrication ports. Use appropriate installation tools to prevent damage to the liner surface during insertion. We recommend confirming that the cylinder liner is correctly seated and checking the bore diameter with precision gauges post-installation to confirm it meets the tolerances specified in the Yanmar service manual.
