11707905 / 11712156 Hydraulic Lift Cylinder Seal Kit — Volvo L330D Wheel Loader (11107383)
Restore the massive lifting power and hydraulic stability of your heaviest equipment with this Lionkits 11707905 / 11712156 Hydraulic Cylinder Seal Kit. Built for the Volvo L330D’s lift cylinder (Part No. 11107383), it’s confirmed to a 110mm piston rod and 200mm cylinder bore, and is specified for machines within the serial number range 61001–70000. Earlier and later L330D production runs may use a different lift cylinder revision, so confirming your machine’s serial number before ordering is worth the extra minute — this is one of the largest, most expensive cylinders on the machine to get wrong.
The L330D is a large-frame loader built for mining and quarry-scale earthmoving, and its lift cylinders carry the full weight of a loaded bucket through every cycle. Because these cylinders run at sustained high pressure rather than brief bursts, seal wear tends to show up first as slow boom drift under load — a subtler warning sign than an external drip, and one worth checking for even before visible leaking appears.
Key Features and Benefits
Confirmed Fitment
Matched to the 110mm rod / 200mm bore profile of lift cylinder 11107383, applicable to L330D units in the 61001–70000 serial number range.
High-Tensile Materials
Manufactured from premium Polyurethane (PU) and NBR components, offering resistance to the high, sustained pressure and abrasive wear typical of large-frame loader lift cylinders.
Thermal Stability
Formulated to perform consistently in extreme temperatures, preventing seal hardening in cold climates or softening under high-heat hydraulic operation.
Superior Contamination Exclusion
Includes a heavy-duty wiper seal designed to scrape away abrasive rock dust and grit, protecting the internal cylinder bore and rod from expensive scoring.
Complete Professional Overhaul
Includes all essential rod seals, piston seals, buffer seals, back-up rings, and O-rings required for a total hydraulic service.
