PC210-8 708-2L-00680 Hydraulic Pump Assembly Overview
The PC210-8 708-2L-00680 Hydraulic Pump assembly manufactured by Tatan is a heavy-duty HPV95 tandem variable displacement axial piston unit belonging to our Hydraulic Pump Assembly classification. Engineered specifically for Komatsu PC210-8, PC210LC-8, and PC210NLC-8 21-ton excavators, replacing your worn hydraulic pump with a Tatan complete assembly eliminates engine bogging, restores simultaneous multi-function speed, and cures internal pressure bypass across demanding quarry and excavation applications.
Built strictly to original Komatsu OEM specifications, this hydraulic main pump incorporates precision micro-lapped bimetal valve plates, calibrated PC/LS regulator blocks, and an integrated auxiliary pilot gear pump, ensuring 100% direct bolt-on installation with flywheel housings and hydraulic control lines.

PC210-8 708-2L-00680 Hydraulic Pump OEM Diagnostic & Troubleshooting Guide
Use this OEM manual hydraulic diagnostic guide to troubleshoot hydraulic pump symptoms on your Komatsu PC210-8 excavator:
| Hydraulic Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Engine stalls / bogs heavily under compound digging | PC regulator valve spool seized or LS differential pressure misadjusted, overloading engine horsepower output. | Replace with Tatan 708-2L-00680 complete hydraulic pump assembly or recalibrate PC/LS regulator springs. |
| 2. Sluggish compound digging movements (arm & boom slow together) | Severe swashplate friction or internal piston shoe wear failing to reach maximum pump stroke displacement. | Inspect swashplate angle sensors; install brand-new Tatan HPV95 pump to restore full 95cc × 2 flow delivery. |
| 3. Hydraulic fluid temperature spikes rapidly under load | High-pressure internal leakage between valve plate and cylinder face caused by cavitation scoring. | Install Tatan new 708-2L-00680 main pump; flush hydraulic tank lines and replace case drain filter element. |
| 4. Loud whining & vibration from pump compartment | Aeration in suction lines or worn shaft bearings causing rotary imbalance under continuous high-load work. | Check suction pipe O-rings, refill clean ISO VG 46 fluid, or bolt on complete replacement hydraulic pump assembly. |
