This boom cylinder seal kit is essential for maintaining the hydraulic integrity of the boom cylinder on Volvo excavators. It comprises various seals and O-rings designed to prevent hydraulic fluid leakage and contamination ingress, ensuring smooth and efficient boom operation. Signs of a failing seal kit include visible leaks from the cylinder rod, slow or jerky boom movements, and a loss of lifting power.
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 most common initial sign of a failing boom cylinder seal kit is visible hydraulic fluid leakage from the cylinder rod seal. If ignored, this leakage will worsen, leading to a gradual loss of hydraulic pressure and slower, less responsive boom movements. Continued operation risks significant hydraulic fluid loss and potential damage to the cylinder bore.
Thoroughly clean the cylinder bore and rod before installing the new seals to prevent damage from debris. Ensure all seals are properly seated and lubricated with clean hydraulic fluid before reassembly.
Inspect the cylinder rod for scoring or pitting, and check the hydraulic fluid for contamination when replacing the boom cylinder seals.
