This is a seal kit designed to replace worn seals within the boom cylinder of Volvo excavators, maintaining hydraulic system integrity. It is manufactured to stringent Volvo standards, ensuring superior sealing performance compared to degraded or damaged original seals. Operators may notice hydraulic fluid leaks around the cylinder rod or sluggish boom movement when these seals begin to fail.
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 visible hydraulic fluid leaks around the boom cylinder rod. If ignored, the leaks will worsen, leading to a gradual loss of lifting power and slower boom operation. Continued operation with failing seals can result in significant hydraulic system contamination and potential cylinder damage.
Ensure the cylinder bore and rod are thoroughly cleaned before beginning seal installation to prevent damage to the new seals. Avoid using sharp tools to pry or force the seals into their grooves, as this can easily cause nicks or tears.
Inspect the cylinder rod for any scoring or damage that could compromise the new seals' effectiveness.
