The HPV95 replaced the older HPV90 with Komatsu's transition to the -6 generation, carrying a new housing and revised shaft while keeping the same 20-tonne equipment class. Genuine Komatsu part numbers for this pump family follow the "708" series format — the prefix identifies hydraulic pump/motor components generally, while the "-2L" suffix specifically marks PC200/PC210/PC220-size pumps (the HPV95 series). A complete PC210-7 assembly is referenced as 708-2L-00300; the updated PC210-8 version is 708-2L-00400.

Common PC210-8 Symptoms & Fault Codes
The HPV95 is known for reliability, but after roughly 6,000-8,000 operating hours, wear symptoms typically appear gradually before becoming severe.
| Symptom | Likely Cause |
|---|---|
| Slightly more noise, slower cycle times | Early-stage wear — worth monitoring, not yet urgent |
| Higher operating temperature than usual | Progressing internal wear or contamination |
| Fault code CA428 on monitor panel | Solenoid valve circuit malfunction on the pump's electronic displacement control — the ECM detects abnormal voltage in the proportional solenoid that regulates pump output, often triggered by a worn/damaged solenoid valve, corroded connectors near the pump mounting bracket, or contaminated oil affecting solenoid response |
| Erratic pressure — surging or dropping unpredictably | Often accompanies CA428; the ECM may enter failsafe mode limiting output to protect the system |
If your PC210-8 is showing CA428, check the wiring harness near the pump mounting bracket for chafing or corrosion before assuming the pump itself has failed — this is a documented weak point on this model. If the harness checks out, the issue is more likely internal to the pump or solenoid.
