This is an arm cylinder seal kit, designed to replace the worn seals within the hydraulic arm cylinder of Volvo excavators. It is manufactured to precise Volvo specifications, ensuring a tight seal and preventing hydraulic fluid leakage, unlike a failed kit where seals become brittle or torn. Operators may observe hydraulic fluid leaking from the arm cylinder rod, or experience a slow drift or loss of holding power in the arm if the seals are compromised.
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.
The first sign of a failing arm cylinder seal kit is often visible hydraulic fluid leakage around the cylinder rod. If left unaddressed, the leakage will worsen, leading to a gradual loss of hydraulic pressure and reduced lifting capacity. Continued operation with leaking seals can result in cylinder damage and contamination of the hydraulic system.
Thoroughly clean the cylinder bore and piston rod before installing the new seals to prevent damage. Ensure the seals are properly seated and not twisted during installation to guarantee a reliable seal.
Inspect the cylinder bore for scoring or damage and check the hydraulic fluid for contamination when replacing the arm cylinder seal kit.
