This is a bucket cylinder seal kit, containing all necessary seals and O-rings to rebuild a worn or leaking hydraulic cylinder on Volvo excavators. It is manufactured from high-quality, durable materials that resist hydraulic fluid and abrasion, ensuring a tight seal and smooth operation unlike a damaged kit that leads to leaks and reduced cylinder performance. Operators will observe external hydraulic fluid leaks from the cylinder rod, slow or jerky bucket movements, or a loss of lifting power 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 indication of a failing bucket cylinder seal kit is typically an external hydraulic fluid leak from the cylinder rod. If left unaddressed, the internal seals can also fail, leading to a loss of hydraulic pressure, resulting in slow or weak bucket operation and reduced digging force. This can significantly impact productivity and potentially cause damage to other hydraulic components due to fluid loss.
Ensure all internal cylinder surfaces, especially the rod and bore, are meticulously cleaned and free of any debris or scoring before installing the new seals. Avoid using sharp tools to pry seals into place, as this can easily nick or cut them, leading to immediate leakage.
Inspect the cylinder rod for scoring or damage and the cylinder bore for wear when replacing the bucket cylinder seal kit.
