This is a boom cylinder seal kit designed to replace worn seals within the boom cylinder of Volvo excavators, maintaining hydraulic pressure and preventing leaks. It is manufactured to meet stringent OEM quality standards, ensuring a reliable seal and smooth cylinder operation compared to a kit with degraded or damaged seals. Operators may notice hydraulic drift, slow or weak boom movement, or external fluid leaks around the boom cylinder 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 sign of a failing boom cylinder seal kit is often a slow drift of the boom when holding a position or a noticeable reduction in lifting power. If ignored, this can progress to significant hydraulic fluid leaks, jerky or unpredictable boom movements, and an inability to hold heavy loads securely. Continued operation with worn seals risks damage to the cylinder rod and bore, leading to more extensive and costly repairs.
Thoroughly clean the cylinder bore and piston rod, inspecting for any scoring or imperfections that could damage the new seals before installation. Ensure all seals are correctly oriented and lubricated to prevent tearing during the initial cycle.
Inspect the hydraulic pump, hoses, and fluid for contamination or wear when replacing the boom cylinder seal kit.
