Description
Technical Overview & Product Details
In marine diesel engine assemblies, “body” O-rings are critical because they seal the primary junctions of major components. These seals must manage not only internal fluid pressure but also the mechanical stresses caused by the engine’s thermal expansion and structural vibration. The 148616-35220 is manufactured to meet Yanmar’s strict material and dimensional standards, ensuring a reliable barrier against oil, fuel, or coolant leaks at critical interface points.
- Compatible Engine Type: Yanmar marine propulsion and auxiliary engine series.
- Part Number / Designation: 148616-35220.
- Component Type: O-Ring (Body/Housing Seal).
- Material: High-performance elastomeric compound (formulated for heat, pressure, and chemical resistance).
- Application: Body/Housing joints (often found in oil/coolant pump bodies, filter housings, or major assembly covers).
Key Features & Performance
- High-Pressure Integrity: Engineered to maintain a seal even under fluctuating internal pressures, ensuring system reliability.
- Thermal Stability: Formulated to withstand the intense temperature cycles of marine engine rooms without hardening, cracking, or losing elasticity.
- Chemical Resilience: Highly resistant to degradation from diesel fuel, lubricating oils, and various coolant additives, ensuring long-term compatibility.
- Vibration Tolerance: Designed to remain seated and effective despite the constant mechanical vibration of a running marine engine.
Why Source from Heybeli Marine?
Leakage at a body joint can be both messy and potentially dangerous if it involves high-pressure fuel or oil circuits. Heybeli Marine protects your vessel’s performance with:
- Strict OEM Interchangeability: Our 148616-35220 seals match the exact material hardness and dimensional tolerances required by Yanmar.
- Global Strategic Logistics: We maintain ready-to-ship inventory of these critical sealing components, ensuring that your maintenance schedules are not disrupted by missing parts.
- Quality Assurance: Every seal is inspected to ensure it is free from flash, molding defects, or surface imperfections, guaranteeing a perfect seal upon installation.
- Complete Overhaul Support: We provide these body O-rings alongside gaskets, fasteners, and other related hardware to facilitate professional, reliable engine service.
Technical Maintenance Note:
To ensure the 148616-35220 provides a secure, leak-proof seal:
- Surface Preparation: Ensure the O-ring groove and the mating “body” surface are perfectly clean. Remove any traces of old sealant or oxidation, as even a small piece of debris can cause a leak in a critical body junction.
- Lubrication: If required by your engine manual, use a light coat of clean assembly lubricant to allow the O-ring to seat properly during assembly.
- Correct Handling: Never use sharp metal tools (like screwdrivers) to seat the O-ring. Use your fingers or a plastic tool to prevent scratching the sealing surface.
- No Reuse: O-rings undergo permanent compression set during service. Always install a new 148616-35220 whenever the associated body/housing is disassembled.
