17478842 Sealing Ring — Volvo FMX FE Series trucks — FH400

This sealing ring is a critical component within the engine's lubrication or cooling system, designed to prevent fluid leakage and maintain optimal operating pressures. It is manufactured to meet stringent material and dimensional standards, ensuring superior sealing performance compared to a worn or damaged ring that can lead to gradual leaks. Operators may notice oil or coolant seepage around the engine block or specific component, which can escalate to visible fluid loss and potential system contamination if left unaddressed.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Initial signs of a failing sealing ring include minor fluid seepage or a slight decrease in system pressure. If ignored, the leakage will worsen, leading to noticeable fluid loss and potential contamination of other engine systems. Continued operation with a compromised seal can result in insufficient lubrication or cooling, risking component damage.

Installation Tip

Ensure the sealing surface on both the ring and the mating component are meticulously clean and free of debris before installation. Avoid stretching or distorting the ring during fitting, as this can compromise its sealing ability.

Service Note

Inspect the mating surfaces for wear or damage and clean them thoroughly before installing the new sealing ring.
