This is a bucket cylinder seal kit, essential for maintaining hydraulic pressure and preventing fluid loss within the bucket cylinder assembly of Volvo excavators. Manufactured to precise Volvo standards, it provides durable sealing performance superior to worn or damaged seals. Signs of a failing seal kit include slow or jerky bucket movements, external hydraulic fluid leaks from the cylinder, and a loss of holding pressure.
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 often visible hydraulic fluid leaking from around the cylinder rod. This will progress to slower, less responsive bucket movements and a loss of the cylinder's ability to hold its position under load. If left unaddressed, the leak can worsen, leading to significant hydraulic system contamination and potential damage to the cylinder rod and bore.
Carefully inspect the cylinder rod for any nicks or scratches that could damage the new seals before installation. Ensure all old seal material is completely removed from the cylinder grooves.
Inspect the cylinder rod for wear or damage, and check the hydraulic fluid for signs of contamination.
