This seal kit contains the elastomeric seals and wiper rings needed to rebuild the hydraulic cylinder on the host tractor. The kit replaces all dynamic and static seals inside the cylinder barrel, between the piston and the rod, and at the rod gland. A leaking cylinder typically shows oil film on the rod or external drips, and the lift or implement response becomes slow or drifts under load. The original manufacturer's seals match the groove geometry and material hardness of the cylinder housing, so the piston maintains its designed compression and the rod wiper keeps contaminants out of the hydraulic loop. During installation, clean the cylinder bore and rod surface thoroughly, and lubricate the new seals with hydraulic fluid before assembly.
