Description
HPK060 9317963 Hydraulic Pump Assembly Overview
The HPK060 9317963 Hydraulic Pump assembly manufactured by Tatan is a heavy-duty tandem variable displacement axial piston unit belonging to our Hydraulic Pump Assembly classification. Engineered specifically for Hitachi ZX130-5G, ZX130K-5G, and ZX120-5A 13-ton crawler excavators, replacing your worn pump with a Tatan complete assembly eliminates compound motion deceleration, restores digging breakout power, and cures internal thermal bypass across demanding utility trenching and quarry projects.
Driven directly by the Isuzu CC-4BG1TC diesel engine and routing pressure flow through the HCV06 main control valve, this HPK060 9317963 Hydraulic Pump combines dual variable piston pumps (2 × 60 cm³/rev) with an integrated auxiliary pilot gear pump, ensuring 100% direct bolt-on installation with flywheel drive couplings and chassis hydraulic hard lines.

HPK060 9317963 Hydraulic Pump Diagnostic & Troubleshooting Guide
Use this technical guide to diagnose common hydraulic pump symptoms on Hitachi ZX130-5G series crawler excavators:
| Hydraulic Fault Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Boom hoisting slows down accompanied by engine bogging | Dual variable regulator power-control spool sticking failing to destroke pump displacement as pressure exceeds 28 MPa. | Replace with Tatan complete HPK060 9317963 Hydraulic Pump assembly with factory-calibrated regulators matched to CC-4BG1TC engine output. |
| 2. Single track pulls to one side during simultaneous blading | P1 or P2 rotary group volumetric loss or swashplate servo piston seal degradation causing uneven flow output. | Install Tatan new tandem pump with precision-matched dual rotating barrel groups; flush contaminated oil lines. |
| 3. Fine bronze glitter & copper dust in return filter element | Piston slipper pads worn thin or separated from swashplate thrust plate due to contaminated hydraulic fluid. | Stop machine immediately to prevent control valve contamination; install fresh complete pump and clean suction strainers. |
| 4. Digging breakout fades rapidly once oil reaches 75°C | Excessive clearance between cylinder barrel face and bimetal valve plate allowing high-pressure fluid to bypass into casing. | Install Tatan new hydraulic pump with micro-lapped bimetal valve plates (< 0.003 mm tolerance) and new suction O-rings. |
