Description
Technical Overview & Product Details
Oil seals of this design are essential for the longevity of rotating components such as crankshafts, pump shafts, and auxiliary drive assemblies. The 24423-355511 is built to handle the rigorous conditions of a marine engine room, including persistent vibrations, thermal cycling, and high-speed rotation.
- Compatible Engine Type: Yanmar marine propulsion and auxiliary engine series.
- Part Number / Designation: 24423-355511 (TC 35x55x11).
- Component Type: Oil Seal (TC Design: Double-lip with garter spring).
- Material: High-grade, oil-resistant synthetic elastomer with steel reinforcement.
- Application: Rotating shaft sealing (crankshafts, water pumps, oil pumps, and transmission drive shafts).
Key Features & Performance
- Dual-Lip Protection: The primary lip ensures oil retention under pressure, while the secondary dust lip prevents contaminants from entering the seal cavity, significantly extending the life of the shaft and bearing.
- Garter Spring Stability: An integrated tensioning spring ensures consistent, uniform radial pressure against the shaft, even as the seal material undergoes natural wear or thermal expansion.
- High-Speed Resilience: Engineered for smooth, low-friction contact that minimizes heat generation during high-RPM operations.
- Chemical & Thermal Resistance: The elastomeric compound is specifically formulated to resist degradation, swelling, or hardening when exposed to hot engine oil and other marine lubricants.

Technical Maintenance Note:
Proper installation is critical for the performance of the 24423-355511:
- Shaft Inspection: Before installing the new seal, inspect the mating shaft for grooves, scratches, or corrosion. A damaged shaft will ruin a new seal instantly. If the shaft is worn, consider using a wear sleeve.
- Cleanliness: Ensure the housing bore is completely free of old sealant, rust, or debris.
- Lubrication: Crucial: Apply a thin film of clean engine oil or assembly grease to the seal lip and the mating shaft surface before installation to prevent dry-start friction.
- Uniform Pressing: Always use a seal installation tool that matches the diameter of the outer metal casing. Press the seal in perfectly square; never hammer directly on the seal face, as this can deform the metal casing or dislodge the spring.
- Directional Integrity: Ensure the dust lip faces the outside (away from the oil reservoir) and the primary sealing lip faces the oil side.
