This is a hydraulic cylinder seal kit designed to replace worn or damaged seals within the bucket cylinder assembly of Volvo and Samsung excavators. It ensures proper sealing to maintain hydraulic pressure and prevent fluid leakage, crucial for smooth and efficient bucket operation. A failed seal kit will typically manifest as slow or jerky bucket movements, external hydraulic fluid leaks around the cylinder rod, and a noticeable loss of lifting or digging power.
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.
External hydraulic fluid leaks around the bucket cylinder rod are the first sign of a failing seal kit. If ignored, the leakage will worsen, leading to a gradual loss of hydraulic pressure and slower, less responsive cylinder operation. Eventually, the cylinder may fail to extend or retract fully, significantly impacting the excavator's operational capability.
Thoroughly clean the cylinder bore and rod before installation to prevent contamination of the new seals. Avoid using sharp tools that could nick or damage the seal lips during insertion.
Inspect the cylinder rod for any scoring or wear that could compromise the new seals' effectiveness.
