M2X210 Swing Motor Assembly 2401-9259A OEM Diagnostic Guide
Use this OEM manual hydraulic diagnostic guide to troubleshoot slewing symptoms on your Doosan DH370-7 excavator or loader:
| Hydraulic/Mechanical Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Slow slewing speed & weak rotation torque under heavy bucket load | M2X210 motor piston shoe wear or anti-reverse relief valve leakage causing internal pressure drop (<29.4 MPa). | Install Tatan M2X210 complete swing motor assembly; flush hydraulic lines and adjust pilot relief valve pressure. |
| 2. Heavy metallic grinding noise in swing reducer gearbox | Planetary gear tooth pitting, sun gear wear, or needle bearing collapse due to insufficient gear oil lubrication. | Replace complete swing motor gearbox assembly; refill with heavy-duty SAE 80W-90 gear oil. |
| 3. Machine upper house drift / Brake slipping on incline 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 drive pinion seal. | Clear casing drain return lines, replace lower pinion shaft seal with high-pressure NOK seal. |
