This is a boom cylinder seal kit designed to maintain hydraulic pressure and prevent fluid leakage within the boom cylinder assembly of Volvo excavators. It is manufactured to meet stringent OEM quality standards, ensuring superior sealing performance compared to worn or damaged seals. Operators may notice a gradual loss of boom control, slow cylinder operation, or visible hydraulic fluid leaks when this seal kit begins to fail.

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.
Initial signs of failure include a slight sponginess in boom control or a slow return to position. If ignored, the leaks will worsen, leading to a significant loss of lifting power and potentially requiring more frequent hydraulic fluid top-offs. Continued operation with a failing seal kit can lead to cylinder damage and compromised machine stability.
Thoroughly clean the cylinder bore and rod before installation to prevent debris from damaging the new seals. Ensure seals are properly oriented and seated without twisting during insertion to guarantee a leak-free seal.
Inspect the cylinder rod and bore for any scoring or damage that could compromise the new seals.
