This is an arm cylinder seal kit designed for Volvo excavators, essential for maintaining the hydraulic system's efficiency and preventing leaks. It seals the internal components of the arm cylinder, ensuring consistent hydraulic pressure for smooth operation and preventing external fluid loss. Failure of this kit will result in visible hydraulic fluid leaks from the cylinder and a noticeable decrease in the excavator's arm lifting and holding power.

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 a failing arm cylinder seal kit is external hydraulic fluid leakage from the cylinder rod. This will progress to a loss of hydraulic pressure, resulting in slower arm movements and reduced lifting capacity. If ignored, the cylinder may not be able to hold its position, posing a risk to operational stability.
Ensure the cylinder rod is clean and free of any burrs or damage before installing the new seals to prevent immediate failure. Do not force the seals into the grooves; they should seat smoothly.
Inspect the arm cylinder rod for scoring or pitting, as any surface imperfections can lead to premature seal failure.
