HPV95 708-2L-00300 Hydraulic Pump Assembly Overview
The HPV95 708-2L-00300 Hydraulic Pump assembly manufactured by Tatan is a high-pressure dual variable axial piston pump belonging to our Hydraulic Pump Assembly classification. Engineered specifically for Komatsu PC200-7, PC200LC-7, PC210-7, and PC220-7 20-to-22 ton excavators, replacing your worn main pump with a Tatan complete assembly restores original 34.3 MPa working pressure, eliminates engine stalling, and guarantees rapid cycle times in tough earthmoving conditions.
Built strictly to original Komatsu OEM specifications, this HPV95 pump assembly features a 14-teeth drive spline shaft and pre-calibrated PC/LS regulator valves, ensuring seamless coupling with Komatsu SAA6D102E-2 diesel engines without any electrical or hydraulic circuit modifications.

HPV95 708-2L-00300 Hydraulic Pump OEM Diagnostic & Troubleshooting Guide
Use this OEM manual hydraulic diagnostic guide to troubleshoot operational symptoms on your Komatsu PC200-7 excavator:
| Hydraulic Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Engine stalls / Lugging down during boom lift or relief | PC-EPC torque control solenoid valve spool sticking, failing to de-stroke swashplate as engine load peaks. | Disassemble and clean EPC regulator spool; recalibrate PC valve spring or install complete Tatan HPV95 pump. |
| 2. Slow compound digging movements under high oil temp | Bimetallic valve plate or cylinder block surface scoring causing high-pressure internal oil bypass (>34.3 MPa drop). | Install Tatan 708-2L-00300 complete pump assembly; flush hydraulic system and install fresh 10μm oil return filter. |
| 3. Loud metallic buzzing noise & vibration in hydraulic tank | Air ingress through suction flange square packing or pilot line aeration creating high-frequency cavitation. | Reseal suction intake with high-temp HNBR square rings; check hydraulic oil level and bleed air from pump casing. |
| 4. Front drive shaft oil seal blown out into engine bellhousing | Casing drain line blockage or internal bypass wear causing casing drain pressure to exceed 0.2 MPa. | Clear case drain return lines, replace front shaft seal with high-pressure NOK seal, and test casing relief pressure. |
