11707025 / 11990349 Hydraulic Lift Cylinder Seal Kit — Volvo L150D Wheel Loader (11107320)
This kit is confirmed to a 90mm piston rod and 170mm cylinder bore, built from PU + NBR + PTFE material for the L150D’s lift cylinder (P/N 11107320). Notably, this isn’t an L150D-exclusive design — the same 11990349 seal specification is shared across the L120C, L150C, and L150D lift cylinders, meaning Volvo carried this cylinder design forward across three model generations rather than redesigning it each time. If you run a mixed fleet of these older Volvo loaders, this is worth knowing for spare parts planning.
The L150D is a workhorse in quarry and bulk material handling operations, where its lift cylinder bears the full weight of a loaded bucket through every cycle. Worth checking before ordering: L150D production used a different tilt cylinder specification before and after serial number 5005, so if you’re servicing multiple cylinders on the same machine, it’s worth confirming your serial number falls where you expect for each individual cylinder rather than assuming all cylinders on the machine share one cutoff point.
Key Features and Benefits
Confirmed Fitment, Cross-Model Compatibility
Matched to the 90mm rod / 170mm bore lift cylinder specification shared across L120C, L150C, and L150D wheel loaders.
Premium Material Grade
Constructed from high-tensile Polyurethane (PU) and specialized NBR/PTFE components for superior resistance to the high-pressure spikes and friction typical of a fully-loaded lift cylinder.
Extreme Durability
Engineered to withstand the intense thermal cycles of continuous operation without hardening or losing its seal.
Contamination Protection
Features a robust wiper seal designed to scrape away grit, dust, and moisture, protecting the internal rod and bore from scoring.
Complete Overhaul Kit
Includes all essential rod seals, piston seals, buffer seals, O-rings, and backup rings for a comprehensive professional repair.

Important Fitment Note
This kit fits the L150D lift cylinder (P/N 11107320) at 90mm rod / 170mm bore, and also fits lift cylinders on L120C and L150C loaders using the same specification. If you’re servicing this machine’s tilt cylinder as well, note that L150D tilt cylinders changed specification around serial number 5005 — please verify your machine’s serial number and cylinder part number before ordering.
