Description
Technical Overview & Product Details
The 146673-11622 is engineered to maintain tight mechanical tolerances within rotating or pivoting connections. The copper-based composition provides an excellent balance of hardness and lubricity, making it an ideal choice for applications where high-frequency loading and thermal expansion are common. By ensuring a precise taper fit, this component minimizes vibration and mechanical play, extending the lifespan of the mating shafts and housing.
- Compatible Engine Type: Yanmar marine propulsion and auxiliary engine series.
- Part Number / Designation: 146673-11622.
- Component Type: Taper Bushing.
- Material: High-grade copper alloy, engineered for thermal efficiency and durability.
- Application: Engine internal assemblies and pivoting pivot points.
Key Features & Performance
- Thermal Management: The copper-based material offers superior heat dissipation, reducing the risk of overheating in high-friction zones.
- Precision Taper Fit: Designed for exact dimensional tolerances to ensure a secure, uniform seating within the housing, preventing migration or rotation.
- Wear Resistance: Built to endure continuous maritime service, the specialized alloy resists abrasive wear and fatigue, even under heavy cyclic loading.
- Operational Stability: Reduces “stick-slip” motion and mechanical play, ensuring smooth movement and maintained alignment within the engine’s valve train or internal linkages.
Why Source from Heybeli Marine?
Improperly fitted or worn bushings can lead to significant engine vibration, reduced efficiency, and increased maintenance costs. Heybeli Marine protects your vessel’s performance with:
- Strict OEM Interchangeability: Our 146673-11622 taper bushes 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 wear parts, ensuring they reach your vessel or shipyard quickly to avoid maintenance delays.
- Quality Assurance: Every batch undergoes dimensional verification to ensure the taper geometry provides a secure, reliable press-fit.
- Complete Overhaul Support: We provide these bushings alongside other internal components, such as seals and bearings, to help you conduct a professional, total engine rebuild.
Technical Maintenance Note:
When installing the 146673-11622, it is vital to use an appropriate press tool that applies force evenly across the entire surface of the bush to prevent distortion or cracking. Ensure the housing bore is perfectly clean and free of burrs or foreign particles. During the overhaul, always check the mating shaft for signs of wear or scoring; a new bushing will fail prematurely if the shaft surface is rough. If specified in the Yanmar service manual, ensure the bush is correctly oriented to align any lubrication ports or channels with the housing.
