This is a sealing ring designed to prevent fluid leakage and maintain pressure within specific components of Volvo motor graders, such as hydraulic cylinders or transmission systems. It is manufactured from durable, oil-resistant rubber compounds that maintain their sealing integrity under pressure and temperature fluctuations, unlike a worn or brittle ring. Operators may observe hydraulic fluid leaks from the component, a loss of hydraulic function, or a drop in system pressure.

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 initial symptom of a failing sealing ring is typically a visible fluid leak from the component it seals, or a gradual loss of hydraulic pressure or function. If ignored, the leak will increase, potentially leading to low fluid levels and damage to associated components due to lack of lubrication or pressure. The worst consequence is component failure or system malfunction due to insufficient hydraulic power or lubrication.
Ensure the sealing surface is perfectly clean and free of any burrs or debris before installing the new ring. Lubricate the ring lightly with the system fluid to aid installation and prevent damage.
Inspect the mating surfaces of the component for wear or damage, and check the fluid level and condition of the system.
