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 material and dimensional standards, ensuring superior sealing performance compared to worn or damaged original seals. Operators may notice a gradual loss of boom control, slow movement, or external hydraulic fluid leaks around the cylinder rod 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.
Initial signs of failure include a slight drift or slow lowering of the boom under load. If ignored, the leakage will worsen, leading to sluggish boom response and potentially external fluid drips. Continued operation with a failed seal kit can result in loss of hydraulic pressure and reduced lifting capacity.
Ensure the cylinder rod is thoroughly cleaned and free of any debris or burrs before installing the new seals to prevent immediate damage. Do not use sharp tools to force the seals into their grooves, as this can compromise their integrity.
Always inspect the cylinder rod and bore for any signs of wear or damage before installing a new seal kit.
