Bucket Cylinder Seal Kit for R360-7 Excavator Hydraulic Repair

This 31Y1-18490 bucket cylinder seal kit is used for Hyundai R360-7 excavator bucket cylinder repair. It is designed to help restore sealing performance when the bucket cylinder has hydraulic oil leakage, pressure loss, weak bucket movement, slow response, or unstable digging force.

The bucket cylinder works continuously during digging, loading, grading, trenching, rock handling, and heavy earthmoving jobs. When the seals become worn, aged, hardened, or damaged, the cylinder may leak oil from the rod side or lose internal pressure. A correct bucket cylinder repair kit helps rebuild the hydraulic cylinder and reduce downtime without replacing the complete bucket cylinder assembly.
