1545271 Sealing Ring | Genuine Volvo Penta Part

🔧 Product Description

This is the late-type sealing ring from the lubricating and oil system group for Volvo Penta marine and industrial engines. It provides the static seal at an oil-system joint, and the "Late type" designation distinguishes it from the earlier-specification ring it replaces, so the later version should be used where this reference applies. It supersedes three earlier part numbers and covers a broad span of older AQ, MD, TMD, TAMD, AD, KAD/KAMD and TD/TWD series engines.

🚤 Compatibility

• Engine Family: MD, TMD, AQ, TD, TAMD, AD, D, TWD, BB, TID, B, TAD, MB, AQD, KAD, KAMD
• HP Range: Approximately 230-450 HP
• Year Range: Approximately 1980s - early 2000s

🔌 Function

The sealing ring forms a static seal at a joint in the engine's lubricating oil system, preventing oil leakage and loss of oil pressure at that connection. It is a routine replacement item whenever the joint it seals is disturbed during service.

⚠️ Common Signs of Failure

• Oil weeping or dripping from the sealed joint
• Hardened, cracked or flattened ring that has lost elasticity
• Loss of oil pressure or falling oil level between services
• Oil residue and dirt build-up around the mating faces
• Distortion or splitting noted on removal during overhaul

🛠️ Service Notes

• Treat as a single-use seal and lubricate only as specified for the engine-oil system.
• Inspect flange 1545272 and the pipe sealing surface; a new ring will not correct a scratched or distorted joint.
