This seal kit contains the elastomeric seals and wiper rings needed to rebuild the lift cylinder on a front loader. The components are sized to the cylinder bore and rod diameter so that the piston and gland can be reassembled with the correct compression and sealing geometry. A worn seal set allows internal leakage past the piston, which causes the loader arm to drift downward under load or reduces lifting force. The kit includes all the O-rings, rod seals, and backup rings that contact the cylinder tube and rod surface. During installation, clean the cylinder bore and rod thoroughly, lubricate the new seals with hydraulic fluid, and avoid nicking the sealing lips on sharp edges.
