The MAG-170VP 20Y-27-00010 Travel Motor Final Drive Assembly manufactured by Tatan is an industrial-grade hydraulic drive unit belonging to our Excavator Final Drive Travel Motor classification. Tailored specifically for Komatsu PC200-7, PC200LC-7, PC210-7, and PC220-7 20-to-22 ton excavators, replacing your worn final drive with a Tatan complete assembly eliminates tracking drift, solves catastrophic gear oil leaks, and restores full gradeability across severe quarry and marshland job sites.
Engineered to original Komatsu specifications, this travel drive integrates a 2-speed axial piston hydraulic motor and a dual-stage planetary reduction gearbox. It mounts directly onto your PC200-7 track frame, providing instant plug-and-play installation without cutting lines or modifying mounting flanges.

MAG-170VP 20Y-27-00010 Travel Motor OEM Diagnostic & Troubleshooting Guide
Use this OEM manual hydraulic diagnostic guide to troubleshoot tracking and final drive symptoms on your Komatsu PC200-7 excavator:
| Hydraulic/Mechanical Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Excavator pulls to one side during travel (Track Dragging) | Internal wear on motor cylinder barrel face or valve plate scoring causing high-pressure oil bypass under 34.3 MPa load. | Replace with Tatan MAG-170VP complete 20Y-27-00010 final drive assembly; inspect center swivel joint seal rings. |
| 2. Dark gear oil leaking behind sprocket hub onto track shoes | Duo-Cone mechanical floating seal faces damaged by abrasive soil, wire wrap, or dry-running heat degradation. | Install complete Tatan replacement travel motor with pre-installed forged alloy Duo-Cone floating seal groups. |
| 3. Loud crunching or grinding noise in planetary gearbox | Sun gear or 1st/2nd stage planetary gear tooth spalling, or needle roller bearing cage collapse due to contaminated gear oil. | Replace complete travel motor gearbox assembly; refill with fresh SAE 80W-90 heavy-duty gear oil before operation. |
| 4. Machine will not shift into Rabbit speed (2-Speed Sticking) | The 2-speed displacement control pilot valve spool is jammed by varnish, or pilot pressure supply line is obstructed (<2.5 MPa). | Flush pilot lines, clean travel speed selector solenoid, or swap to a Tatan factory pre-tested complete travel motor. |
