Stoll - 3474010 - Loader Lift Cylinder Seal Kit D40 mm

This seal kit contains the elastomeric seals and wiper rings for the lift cylinder of a front loader. The kit is designed to restore the hydraulic seal at the rod and piston interfaces, preventing external leakage and internal bypass. A failing seal in this location causes the loader arms to drift downward under load and may show visible oil streaks on the cylinder rod. The seals are dimensioned to match the original cylinder bore and rod diameter, so the piston and gland nut can be reinstalled without shimming or modification. On reassembly, lubricate the seals with clean hydraulic fluid and torque the gland nut to the manufacturer's specification.
