HPV35 708-2L-00030 Hydraulic Pump OEM Diagnostic Guide
Use this professional diagnostic reference when evaluating hydraulic health on Komatsu PC60-7 machines:
| Hydraulic Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Sluggish Cylinder Speed under High Oil Temperature | Thermal clearance expansion in worn cylinder blocks causing high-pressure oil internal bypass (>26.5 MPa drop). | Install Tatan HPV35 708-2L-00030 Hydraulic Pump assembly; flush hydraulic system and replace 10μm return filter. |
| 2. Engine Stalling / Lugging Down when operating boom or bucket | Total power control regulator spool sticking or incorrect negative flow control (NFC) pressure setting. | Calibrate regulator pressure or upgrade directly to a factory-tested complete Tatan pump assembly. |
| 3. Loud Cavitation Whining & Oil Foaming in Reservoir | Air ingestion through suction flange gaskets or cracked suction hose lines starving the pump inlet. | Replace high-temp HNBR suction O-rings and perform vacuum air bleeding. |
| 4. Front Drive Shaft Oil Seal Blowout into Engine Bellhousing | Casing drain line blockage or internal case pressure spike exceeding 0.2 MPa. | Clear case drain return lines, replace shaft seal with high-pressure NOK seal, and test relief pressure. |
