This is a dipper arm cylinder seal repair kit designed to restore the sealing integrity of the dipper arm cylinder on Volvo excavators. It is manufactured to meet stringent OEM quality standards, ensuring superior durability and performance compared to worn or damaged seals that can lead to leaks and reduced boom/dipper function. Operators may notice slow or jerky dipper arm movements, external hydraulic fluid leaks around the cylinder rod, or a loss of holding pressure when the dipper is extended or retracted.

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.
Observable signs include sluggish or uncontrolled dipper arm movement and visible hydraulic fluid seepage from the dipper cylinder rod. If left unaddressed, these symptoms will progress to a noticeable loss of digging power and potential hydraulic system overheating. Continued operation risks damage to the cylinder rod and internal hydraulic components due to pressure loss.
Carefully inspect the cylinder rod for any nicks or scratches before installing new seals, as even minor imperfections can cause premature failure. Ensure all seals are lubricated with clean hydraulic fluid before insertion to prevent tearing.
Check the condition of the hydraulic fluid and consider replacing the hydraulic filter element as part of this service.
