This arm cylinder seal kit is designed to replace the worn seals within the hydraulic arm cylinder of Volvo excavators, preventing hydraulic fluid leaks and maintaining proper cylinder function. Manufactured to meet Volvo's high-quality standards, it ensures a reliable seal compared to a degraded kit that would allow fluid bypass. Operators may notice hydraulic fluid leaks around the arm cylinder, slow or jerky arm movements, or a loss of lifting capacity when this seal kit fails.
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 indication of a failing arm cylinder seal kit is often visible hydraulic fluid leakage from the cylinder rod or barrel. If left unaddressed, the leakage will worsen, leading to a gradual loss of hydraulic pressure and reduced cylinder performance. This can compromise the excavator's ability to lift and maneuver effectively, impacting productivity.
Carefully clean the cylinder bore and piston rod before installing the new seals to prevent damage from debris. Ensure all seals are properly seated and lubricated before reassembly to prevent tearing.
Inspect the cylinder bore for scoring or damage, and check the hydraulic fluid level and condition when replacing the arm cylinder seal kit.
