Description
Tatan M2X96 4247870 Swing Motor Assembly Overview
The M2X96 4247870 Swing Motor is an axial piston rotary hydraulic unit built for the superstructure slewing circuit of Hitachi EX200-2, EX200LC-2, and EX200K-2 excavators. Built in accordance with ISO fluid power standards, installing this complete assembly resolves turret drift on slopes, internal oil bypass, and low slewing torque failures without requiring custom hydraulic line fabrication.
The unit incorporates a Kawasaki M2X96 rotating group, valve plate, housing, and internal mechanical parking brake mechanism, matching original mounting bolt circles and gearbox spline depths.

M2X96 4247870 Swing Motor Diagnostic Guide
Technical troubleshooting steps for Hitachi EX200-2 slewing circuit faults:
| Hydraulic Symptom | Root Cause Analysis | Tatan Factory Solution |
|---|---|---|
| 1. Superstructure drifts downhill on an incline | Worn mechanical parking brake friction discs or internal piston block bypass. | Replace with complete Tatan M2X96 4247870 Swing Motor. |
| 2. Low slewing torque from a dead stop | Scored valve plate mating surfaces or weak crossover relief valve springs. | Check pilot pressure loop and install a new pre-tested motor assembly. |
| 3. Metallic grinding noise during rotation | Contaminated hydraulic oil causing planetary gearbox or bearing failure. | Clean swing reduction gearbox housing and install fresh motor assembly. |
| 4. External shaft oil leakage | Damaged high-pressure shaft seal due to high case-drain backpressure. | Inspect return line restrictions and replace motor unit. |
