This seal kit is designed to replace the worn or damaged seals within the bucket cylinder of Volvo excavators, preventing hydraulic fluid leakage and maintaining system pressure. It is constructed from durable, high-quality materials that resist wear, heat, and hydraulic fluid degradation, outperforming compromised seals on a failing cylinder. Operators may notice external fluid leaks around the cylinder rod, or a gradual loss of bucket curl force and holding power.
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 bucket cylinder seal is often visible hydraulic fluid leakage around the cylinder rod or a noticeable decrease in the bucket's ability to hold its position under load. If ignored, the leakage will increase, leading to reduced hydraulic pressure and power, making the bucket sluggish and potentially unable to perform its intended tasks.
Thoroughly clean the cylinder bore and rod to prevent damaging the new seals during installation. Ensure all seals are correctly oriented according to the manufacturer's diagrams to prevent immediate failure.
Inspect the hydraulic fluid for contamination and check the cylinder rod for scoring or damage before installing the new seal kit.
