Sustained load and contaminated oil gradually damage critical contact surfaces, producing weak force, drifting motion, abnormal noise or overheating. The 4610138 Hitachi Excavator Swing Drive Assembly fits Hitachi ZX200, ZX200-3, ZX210, ZX220, EX200-5 excavators, providing reliable torque transmission and smooth operation that keeps your fleet moving.
