This is a bucket cylinder seal kit, designed to restore the sealing integrity of the bucket cylinder on Volvo and Samsung excavators. Manufactured with robust materials that meet stringent OEM specifications, it ensures reliable performance and durability against wear and hydraulic pressure. Operators will typically notice hydraulic fluid leaking from the bucket cylinder rod, a reduction in bucket breakout force, or sluggish bucket movements when this seal kit is required.

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 primary symptom of worn bucket cylinder seals is the appearance of hydraulic fluid leaking along the cylinder rod. This leakage often results in a noticeable decrease in the bucket's lifting and digging power due to pressure loss. If the seals are not replaced, the cylinder may eventually fail to hold position, leading to uncontrolled bucket movement and potential damage to the cylinder components.
Ensure the cylinder rod is perfectly clean and free of any burrs or scratches before installing the new seals to prevent immediate damage. Do not use sharp tools to pry the seals into place; use appropriate seal-driving tools to avoid nicking or distorting them.
Inspect the cylinder rod for straightness and surface finish, check the piston seals, and clean the cylinder bore thoroughly.
