This is a hydraulic cylinder seal kit specifically designed for the bucket cylinder on Volvo EC290B and EC360B excavators. It contains all necessary seals to restore the cylinder's integrity, preventing internal and external fluid leaks and ensuring optimal bucket control. Symptoms of a worn seal kit include a spongy or slow-reacting bucket, external fluid leaks from the cylinder, and a noticeable reduction in digging force.
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.
A primary indicator of a failing bucket cylinder seal kit is a gradual loss of bucket curl or dump speed. If left unaddressed, the cylinder may develop external leaks, leading to a significant drop in hydraulic pressure and reduced digging power. The ultimate consequence is the inability to effectively control or hold the bucket position, hindering excavation tasks.
Before installing the new seals, carefully inspect the cylinder rod for any imperfections that could damage the sealing surfaces. Ensure all old seal material is completely removed from the grooves.
Check the hydraulic fluid level and condition, and inspect the hydraulic pump for proper operation when replacing bucket cylinder seals.
