This is a floating seal assembly used in the final drive or hydraulic systems of Volvo excavators to prevent the ingress of contaminants and the egress of lubricant. Constructed with durable sealing faces, it provides a reliable seal compared to a worn or damaged seal that allows leakage. Operators may observe hydraulic fluid leaks or notice increased wear in the final drive if this seal fails.

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 sign of a failing floating seal is often visible leakage of oil or grease from the final drive or hydraulic component. If left unaddressed, this leakage will continue, leading to a loss of lubricant or hydraulic pressure and allowing contaminants to enter the system. This can cause accelerated wear and potential damage to gears, bearings, or hydraulic components.
Carefully clean both sealing surfaces (the housing and the shaft or mating component) before installing the new seal to ensure a proper seal and prevent contamination. Avoid using sharp tools to pry the seal into place, as this can easily damage the delicate sealing lips.
Inspect the mating surfaces for any nicks, burrs, or excessive wear that could compromise the effectiveness of the new floating seal.
