This seal kit is specifically designed to replace worn or damaged seals within the bucket cylinder of a Volvo excavator, preventing hydraulic fluid leaks and maintaining proper system pressure. It is constructed from durable materials that resist wear and chemical degradation, offering superior sealing performance compared to a compromised original seal. Operators may notice hydraulic fluid seeping from the cylinder rod, slow or jerky bucket movements, or a loss of lifting force when this seal kit is needed.
Always verify with serial number before ordering.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The most common initial symptom of worn bucket cylinder seals is visible hydraulic fluid leakage from the cylinder rod. If left unaddressed, this leakage will worsen, leading to a gradual loss of hydraulic pressure and slower, less responsive bucket operation. The ultimate consequence is a significant reduction in the excavator's digging and lifting capabilities.
Ensure the cylinder bore and rod are meticulously cleaned and inspected for any imperfections before installing the new seals. Avoid using sharp tools that could nick or damage the delicate sealing surfaces.
Inspect the cylinder rod for scoring or damage and clean the cylinder bore thoroughly when replacing the bucket cylinder seals.
