This floating seal ring is a precision-engineered component used in the final drive or hydraulic system of Volvo excavators to prevent the leakage of lubricant and the ingress of contaminants. It creates a dynamic seal between rotating and stationary parts, crucial for maintaining hydraulic pressure and protecting bearings. A worn or damaged seal ring will result in lubricant leakage and allow dirt and water to enter the system, leading to premature wear of gears and bearings.

Cross-reference part number with serial number before ordering to confirm fitment. Keep original parts until new ones are confirmed correct. Record part numbers replaced for future reference.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first indication of a failing floating seal ring is often visible lubricant leakage around the final drive or hydraulic motor housing. If ignored, this leakage will worsen, leading to insufficient lubrication of gears and bearings. The ultimate consequence is accelerated wear, potential seizure of components, and costly repairs to the final drive or hydraulic system.
Clean the seal grooves and mating surfaces meticulously before installation to ensure a proper seal. Ensure the seal faces are lubricated with the appropriate grease before assembly to prevent initial damage.
Inspect the gears, bearings, and housing for any signs of wear or damage when replacing floating seal rings.
