This is a hydraulic cylinder seal kit designed to maintain the integrity of the boom cylinder in Volvo excavators. It ensures proper sealing to prevent fluid leakage and maintain system pressure, crucial for smooth operation. Failure of these seals typically manifests as external fluid leaks around the cylinder rod, sluggish boom movement, or a noticeable drop in hydraulic pressure during operation.

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.
External hydraulic fluid leaks around the boom cylinder rod are the first sign of seal failure. If ignored, this can lead to a gradual loss of lifting power and slower boom actuation. Continued operation with compromised seals risks internal cylinder damage and potential loss of hydraulic system pressure.
Ensure the cylinder rod is clean and free of any burrs or scoring before installing new seals. Avoid using sharp tools that could nick or cut the new seals during insertion.
Inspect the cylinder rod for any signs of wear or damage that could prematurely wear out the new seals.
