This arm cylinder seal kit is designed to replace the worn seals within the hydraulic arm cylinder of the excavator, preventing hydraulic fluid leaks and maintaining proper cylinder function. Manufactured with durable materials, it ensures a tight seal and reliable operation, unlike degraded seals that allow fluid bypass and reduced performance. Operators may notice hydraulic fluid leaks around the arm cylinder, slow or jerky arm movements, or a loss of holding pressure 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.
Visible hydraulic fluid leaks around the arm cylinder rod or seals are the most common initial sign that a seal kit is needed. If left unaddressed, the cylinder may lose its ability to hold position under load, leading to slow or erratic arm movements. This can result in reduced excavation efficiency and potential safety hazards due to unpredictable equipment behavior.
Carefully clean the cylinder bore and piston rod before installing the new seals to prevent damage from debris. Ensure all seals are oriented correctly according to the cylinder's design to prevent immediate failure.
Inspect the cylinder barrel and piston rod for any scoring or damage that could cause premature seal failure when replacing the seal kit.
