Description
HMGF40FA 9261222 Travel Motor Assembly Overview
The HMGF40FA 9261222 Travel Motor assembly manufactured by Tatan is a heavy-duty integrated hydraulic final drive unit combining a dual-speed axial piston motor and planetary reduction gearbox. Belongs to our Travel Motor Final Drive Assembly classification. Engineered specifically for Hitachi ZX200-3, ZX200LC-3, ZX210-3, and ZX240-3 20-ton crawler excavators, replacing your worn final drive with a Tatan complete assembly eliminates single-side track steering deviation, restores crawling gradeability on muddy inclines under 203 kN tractive demand, and cures planetary gear grinding across demanding utility trenching and quarry applications.
Driven directly by the machine’s HPV118 hydraulic pump and routed through the C0170 main control valve, this HMGF40FA 9261222 Travel Motor incorporates 20CrNiMo carburized planetary gears, Duo-Cone mechanical face seals, a hydraulic parking brake pack, and a built-in counterbalance valve, ensuring 100% direct bolt-on installation with track frames, drive sprockets, and chassis hydraulic lines.

Application Scenarios & Buyer Value
When contractors search to compare Hitachi ZX200-3 final drive replacement cost and upgrade their undercarriage with our HMGF40FA 9261222 Travel Motor, they secure measurable field reliability and lower cost per hour:
| Application Scenario | Value Delivered to Buyer |
|---|---|
| Hitachi ZX200-3 Drive Replacement | 1:1 direct bolt-on installation eliminates track wandering on muddy terrain and restores full 5.5 km/h high-gear travel speed. |
| Heavy Equipment Repair Workshops | Avoids the complex labor of pressing planetary gear carriers and setting bearing preload shims; drops on as a pre-tested sealed unit. |
| Quarry & Heavy Earthmoving Fleets | Carburized planetary gears and heavy Duo-Cone mechanical face seals withstand continuous mud immersion and rocky trail crawling under 203 kN drawbar pull. |
| Machinery Parts Stockists | High-demand 20-ton final drive inventory packaged in solid export wooden crates ready for immediate global air or ocean dispatch. |
HMGF40FA 9261222 Travel Motor Diagnostic & Troubleshooting Guide
Use this technical guide to diagnose common final drive and planetary reduction gearbox issues on Hitachi ZX200-3 series excavators:
| Hydraulic Fault Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Track pulling to one side during straight crawling | Travel motor valve plate scoring causing excessive case-drain bypass, or counterbalance spool sticking partially closed on weak side. | Replace with Tatan complete HMGF40FA 9261222 Travel Motor assembly or flush counterbalance valve pilot galleries. |
| 2. Motor fails to shift between Low (Tortoise) and High (Hare) speed | Two-speed shift pilot spool jammed by oil contamination, or swashplate minimum angle control piston seals degraded. | Inspect 3.9 MPa shift pilot pressure at motor port, clean 2-speed selector valve, or replace travel drive unit. |
| 3. Black gear oil leaking from sprocket hub into track chains | Duo-Cone mechanical face floating seal rings worn out or wire/packing rope wrapped around sprocket cutting O-rings. | Stop machine immediately to prevent planetary gear seizure; install fresh Tatan factory-sealed final drive. |
| 4. Loud grinding & clunking sound from track drive hub | Planetary sun gear tooth fracture or needle roller bearing failure caused by operating with low gear oil level. | Drain gear oil to check for metal debris; replace complete gearbox assembly to prevent main track frame lockup. |
