Hyundai Main Pump Parts

Precision Internal Parts to Rebuild, Restore, and Extend Pump Life

When a main hydraulic pump loses pressure, you don't always need to replace the entire unit. Often, the housing is perfectly intact, but internal wear-and-tear has taken a toll on the high-friction rotating groups. Replacing key internal components is a highly cost-effective way to restore your Hyundai excavator’s factory hydraulic pump without the price tag of a full replacement pump.

We supply a comprehensive inventory of heavy-duty, precision-engineered internal components for Hyundai OEM main pumps used across the Robex and HX/HW series lineups.

We stock complete rotary groups and individual rebuild components for the most common pump models found in Hyundai machines.

Why Rebuild Your Hyundai Pump with Our Parts?

• Micron-Level Precision: Our parts are engineered to exact OEM dimensions, guaranteeing that new components will seamlessly integrate with your existing pump housing.

• In-Stock Rebuild Kits: We package complete "Rotary Group Kits" (Cylinder block + Pistons + Valve Plate + Set Plate) so you get everything required for a successful overhaul in one box.

Don't let a poorly machined part ruin a costly rebuild. Give our team your Hyundai Machine Model, Serial Number, or the data tag info from your pump casing, and we will track down the exact internal components you need to get back to work.
