Arm / Stick Hydraulic Cylinder to Suit Komatsu PC100-5, PC120-5 Excavator

Bring back crisp, consistent stick travel on the Komatsu PC100-5, PC120-5 with a complete arm cylinder assembly from Lucas Parts. Supplied as a ready-to-fit unit — barrel, rod, piston, gland and seals — it's built to OEM specifications for a direct bolt-on replacement with no rebuilding required.

A worn or leaking arm cylinder shows up as slow or drifting stick movement, oil weeping at the gland, or a scored rod that keeps chewing through seals. Rather than losing days to a rebuild, swap in a complete new assembly and get the machine straight back to work. In the 12–15 tonne class, these machines handle road works, bulk trenching and site clearing — heavy cycles that wear seals and rods faster than most owners expect.
