Hitachi ZX20T-5APUMPKIT HYDRAULIC PUMP REPAIR KIT 4HK1 is applicable to models such as DCXB0:ZX200-5A.

The excavator hydraulic pump repair kit is an all-in-one collection of maintenance parts designed to address common faults of excavator hydraulic pumps (such as leakage, insufficient pressure, abnormal noise, and unsmooth operation). It is especially compatible with mainstream models like the Hitachi ZX/EX series, requiring no additional adaptation or modification.

It includes OEM-grade seals (O-rings, oil seals), precision piston assemblies, wear-resistant valve plates, imported bearings, high-pressure sealing rings, and dedicated disassembly tools, covering core fault points of hydraulic pumps such as seal failure, component wear, and pressure loss.

The components are made of materials that meet OEM standards, featuring high pressure resistance (up to 38MPa), wear resistance, and high temperature resistance. After repair, the working pressure and flow of the hydraulic pump can be quickly restored, bringing the excavator's digging force and operational coordination back to normal. Moreover, its cost is only 1/5 of that of a new pump, significantly reducing maintenance costs and downtime losses. It is suitable for professional repair shops, equipment rental companies, and excavator owners.
