This is an adjust cylinder seal kit crucial for maintaining the proper function of the hydraulic system in Volvo excavators. It prevents internal and external leakage of hydraulic fluid from the adjust cylinder, ensuring smooth operation of the undercarriage or boom adjustment mechanisms. Operators may notice a slow drift or inability to hold position on the adjusted component, along with visible fluid leaks, 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 initial symptom of a failing adjust cylinder seal kit is often a slow drift or inability of the adjusted component to maintain its set position. This is usually accompanied by visible hydraulic fluid leaks around the cylinder rod. If ignored, the leakage will increase, potentially leading to a significant loss of hydraulic pressure and control over the adjusted function.
Before installing, carefully inspect the cylinder rod for any imperfections that could damage the new seals. Ensure all old seal material is completely removed from the gland.
Check the hydraulic fluid level and condition, as leaks can lead to contamination and reduced system performance.
