This is an arm cylinder seal kit specifically designed for the hydraulic arm cylinder of Volvo excavators, ensuring proper sealing and function. It is manufactured to meet stringent quality standards, providing reliable performance and durability against wear and hydraulic pressure. Operators may observe hydraulic fluid leaks from the arm cylinder, a loss of lifting capacity, or slow and jerky arm movements when this seal kit begins to deteriorate.
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 around the arm cylinder rod is the primary indicator of a failing seal kit. If ignored, this leakage will increase, leading to a loss of hydraulic pressure and reduced arm lifting power. Continued operation can result in internal cylinder damage and contamination of the hydraulic system.
Before installing, carefully clean the cylinder bore and rod to remove any dirt or debris that could damage the new seals. Ensure the seals are lubricated with system-compatible hydraulic fluid.
When replacing the arm cylinder seal kit, inspect the cylinder rod for scoring and check the hydraulic fluid and filters for contamination.
