This boom cylinder seal kit is designed to replace worn or damaged seals within the boom cylinder assembly of Volvo Samsung excavators, preventing hydraulic fluid leaks and maintaining proper cylinder function. Manufactured to precise tolerances, these seals restore the cylinder's integrity, ensuring it holds pressure effectively, unlike a worn kit where fluid bypasses seals. Operators will typically observe hydraulic fluid leaking externally around the cylinder rod or a noticeable loss of lifting capacity and boom control when the seals 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.
The first sign of a failing boom cylinder seal kit is often visible hydraulic fluid leakage from the cylinder rod seal or around the cylinder base. If ignored, this leakage will worsen, leading to a gradual loss of hydraulic pressure and reduced lifting capacity or control over the boom. Prolonged operation with leaking seals can lead to internal cylinder damage and contamination of the hydraulic system.
Carefully inspect the cylinder rod for any nicks or scoring before installing new seals, as imperfections can quickly damage the new seals. Ensure all old seal material is completely removed from the gland grooves to guarantee a proper seal.
When replacing boom cylinder seals, inspect the cylinder rod for straightness and the cylinder bore for scoring, and check the hydraulic fluid for contamination.
