Description
HPV95 708-2L-00680 Hydraulic Pump Assembly Overview
The HPV95 708-2L-00680 Hydraulic Pump assembly manufactured by Tatan is a heavy-duty dual-tandem variable displacement axial piston unit belonging to our Hydraulic Pump Assembly classification. Engineered specifically for Komatsu PC240-8, PC240LC-8, and PC240NLC-8 24-ton excavators, replacing your worn hydraulic pump with a Tatan complete assembly eliminates engine stalling under load, restores simultaneous multi-function speed, and cures internal pressure bypass across demanding quarry and excavation applications.
Driven directly by the SAA6D107E-1 diesel engine and routing high-pressure fluid through the PC240-8 main control valve, this hydraulic main pump incorporates precision micro-lapped bimetal valve plates, calibrated PC/LS regulator blocks, PC-EPC solenoids, and an integrated auxiliary pilot gear pump, ensuring 100% direct bolt-on installation with flywheel housings and chassis hydraulic lines.

HPV95 708-2L-00680 Hydraulic Pump OEM Diagnostic & Troubleshooting Guide
Use this OEM manual hydraulic diagnostic guide to troubleshoot hydraulic pump symptoms on your Komatsu PC240-8 excavator:
| Hydraulic Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Engine stalls / bogs heavily (憋车) during compound dig | PC-EPC proportional solenoid coil degraded or PC regulator spool seized, failing to destroke pump swashplate under 134 kW peak load. | Test PC-EPC solenoid resistance (7.5-14.5 Ω), recalibrate PC valve spring, or install Tatan pre-calibrated HPV95 unit. |
| 2. Sluggish movement across all cylinders | Self-reducing pressure valve spool seized by contamination, dropping pilot supply below 2.0 MPa (target 3.9 MPa). | Inspect pilot gear pump pressure; clean self-reducing valve spool or replace complete Tatan pump assembly. |
| 3. Bronze glitter & brass shavings in return filter element | Piston shoe slipper retaining plate failure or bronze valve plate scoring under continuous breaker hammer vibration. | Stop operation immediately; flush hydraulic tank and lines, install Tatan new 708-2L-00680 pump and new return filter. |
| 4. Screeching whining noise and high case-drain heat (> 85°C) | Cradle swashplate support bearings worn or suction hose liner delamination starving rotary barrel suction ports. | Inspect suction line O-rings, replace hydraulic fluid with clean ISO VG 46, and bolt on new balanced main pump. |
