GM09 203-60-00100 Travel Motor OEM Diagnostic Guide
Use this OEM manual diagnostic guide to troubleshoot tracking and travel motor issues on your Komatsu PC120-6 excavator:
| Hydraulic/Mechanical Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Excavator tracking off-steer / One side slow | Worn motor piston cylinder block or pilot swashplate angle wear causing internal oil bypass under 31.4 MPa load. | Replace with Tatan GM18 complete 203-60-00100 final drive motor assembly; check center swivel joint seals. |
| 2. Gear oil leaking into track sprocket hub | Duo-Cone floating seal face damage or rubber O-ring degradation allowing gear oil to escape from hub. | Replace complete final drive assembly or install high-durability forged steel Duo-Cone floating seal kit. |
| 3. Loud metallic grinding noise during travel | 1st or 2nd planetary gear tooth breakage or needle bearing collapse due to insufficient gear oil lubrication. | Install Tatan new complete travel motor with gearbox; refill with SAE 80W-90 heavy-duty gear oil before operation. |
| 4. High-speed (Rabbit speed) shift failure | 2-speed shift pilot control spool sticking or pilot line pressure drop (<2.5 MPa) to swashplate piston. | Clean 2-speed control valve spool, check pilot shift pressure, or replace complete travel motor assembly. |
