KMX 708-2L-00360 Swing Motor OEM Diagnostic Guide
Use this professional diagnostic reference when evaluating slewing health on Komatsu PC130-8 machines:
| Hydraulic/Mechanical Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Sluggish Rotation & Weak Swing Torque under heavy bucket load | Internal piston shoe wear or anti-reverse valve leakage causing pressure drop (<29.4 MPa). | Install Tatan KMX 708-2L-00360 Swing Motor assembly; flush hydraulic lines and adjust pilot relief valve pressure. |
| 2. Heavy Metallic Grinding Noise in slewing reducer gearbox | Planetary gear tooth pitting, sun gear wear, or needle bearing collapse due to old gear oil. | Replace complete swing motor gearbox assembly; refill with heavy-duty SAE 80W-90 gear oil. |
| 3. Upper House Drifting / Brake Slipping on inclined slopes | Multi-disc wet parking brake friction plate wear or brake release pilot pressure line leakage. | Inspect brake release pilot pressure (>2.5 MPa); replace brake friction plates or install new swing motor assembly. |
| 4. Gear Oil Leaking into Swing Bearing Tub | Lower shaft oil seal breakdown or casing drain line pressure spike blowing out pinion seal. | Clear casing drain return lines, replace lower pinion shaft seal with high-pressure NOK seal. |
