This is a boom cylinder seal kit designed to replace worn or leaking seals within the boom cylinder assembly of Volvo excavators. It is manufactured to meet Volvo's rigorous material and dimensional specifications, ensuring a tight seal and smooth operation unlike a damaged kit that leads to hydraulic fluid loss. Operators will typically observe a visible leak of hydraulic fluid from the boom cylinder, or a slow, uncontrolled lowering of the boom 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 first sign of a failing boom cylinder seal kit is usually visible hydraulic fluid leakage around the cylinder rod or at the cylinder base. If ignored, the leak will worsen, leading to a gradual loss of lifting capacity and uncontrolled boom drift. Continued operation with a compromised seal kit can result in significant hydraulic system contamination and potential damage to the cylinder rod.
Thoroughly clean the cylinder bore and rod before installing new seals to prevent damage from debris. Ensure all seals are correctly oriented to prevent immediate leakage upon system pressurization.
Inspect the cylinder rod for scoring or damage and clean the hydraulic fluid reservoir for contamination when replacing the boom cylinder seal kit.
