M5X130CHB 4625367 Swing Motor Assembly Overview
The M5X130CHB 4625367 Swing Motor Assembly manufactured by Tatan is a heavy-duty axial piston rotary hydraulic motor belonging to our Excavator Swing Motor Assembly classification. Engineered specifically for Hitachi ZX250-3, ZX250LC-3, ZX250H-3, and ZX250K-3 25-ton mining excavators, swapping a worn or internally leaking motor with this complete M5X130CHB 4625367 Swing Motor Assembly unit resolves turntable drift, sluggish slewing acceleration, and hydraulic chatter under heavy 25-ton quarry cycles.
Constructed strictly to original Kawasaki M5X130 engineering tolerances, this complete unit integrates a 130 cc axial piston cylinder block, precision-lapped bi-metal valve plate, dual anti-shock crossover relief valves, and an internal multi-disc mechanical parking brake. It delivers immediate hydraulic response and mounts directly to the original Dash-3 reduction gearbox with zero bracket modifications.

M5X130CHB 4625367 Swing Motor Assembly OEM Diagnostic Guide
Use this technical diagnostic guide to identify slewing circuit and braking faults on your Hitachi ZX250-3 excavator:
| Slewing Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Superstructure drifts or creeps when parked on an incline | Worn mechanical parking brake friction discs or fatigued brake return springs failing to clamp the rotating group when pilot pressure drops. | Replace with a complete factory-tested M5X130CHB 4625367 Swing Motor Assembly. |
| 2. Sluggish slewing acceleration or weak rotation breakout torque | High internal oil bypass across scored valve plates and worn piston shoes, dropping motor working pressure below 23.0 MPa. | Inspect pilot control line pressure (3.9 MPa) and replace with a brand new high-torque Tatan swing motor. |
| 3. Violent mechanical shudder or banging noise when stopping swing | Crossover shockless relief valve cartridge jammed with metal contaminants or cracked relief poppet springs. | Flush motor drain gallery, replace hydraulic return filters, and install a pre-calibrated replacement motor. |
| 4. External hydraulic oil leaking past the motor output shaft seal | Excessive casing backpressure (> 0.25 MPa) blowing out the high-pressure shaft seal due to a restricted or pinched case-drain line. | Check and clear case-drain line restrictions and install a new sealed motor unit with dual lip seals. |
