This is an arm cylinder seal kit, essential for maintaining the integrity of the hydraulic arm cylinder by preventing fluid leaks and keeping contaminants out. Manufactured to meet Volvo's high standards, this kit provides durable seals that outperform worn or degraded ones, ensuring proper cylinder function. Operators may notice hydraulic fluid leaks around the arm cylinder, slow or jerky arm movements, or a loss of lifting capacity when the seals in this kit fail.
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 leakage from the arm cylinder rod seal or rod wiper is usually the first indication of seal failure. If left unaddressed, the leakage will worsen, leading to reduced hydraulic pressure and slower, less responsive arm movements. Eventually, significant fluid loss can impair the machine's overall hydraulic performance and potentially damage the cylinder bore.
Carefully clean the cylinder bore and piston rod before installing the new seals to prevent damage. Ensure all seals are properly seated and lubricated with clean hydraulic fluid before reassembly.
Inspect the cylinder bore for scoring or damage and clean the hydraulic filter when replacing the arm cylinder seals.
