This gasket set provides the seals needed to rebuild the hydraulic cylinder that controls the three-point hitch linkage. The set contains all the static and dynamic seals that fit between the piston, rod, and cylinder housing. A worn seal set allows internal leakage, which causes the hitch to drift or fail to hold position under load. Replacing the entire set restores the cylinder's ability to maintain hydraulic pressure without bypass. During installation, clean the cylinder bore and rod surface thoroughly, and lubricate the new seals with clean hydraulic fluid before assembly.
