ZX670-5G ZX670 Travel Reduction for Hitach Excavator spare parts 9254462 Walking Reducer Assembly OEM

OEM Part Number: 9254462 | Walking Reducer Assembly

The travel gearbox is a critical component in an excavator's undercarriage system, responsible for transmitting power from the hydraulic motor to the tracks or wheels, enabling precise movement and heavy-duty operation. Its reliability directly impacts the machine's productivity in mining, construction, and earthmoving applications.

• High-quality excavator travel gearboxes use high-strength alloy steel forged gears
• After carburizing and quenching treatment, surface hardness reaches HRC58-62 for high wear and impact resistance
• Capable of withstanding long-term heavy-load operation
• Internal lubricating oil circuit features forced lubrication design
• Ensures gears and bearings are fully lubricated during high-speed operation, reducing friction loss
• Gearbox shell made of die-cast aluminum alloy or cast iron for light weight and deformation resistance
• Adapts to harsh outdoor construction environments

During maintenance, regularly check the oil level and oil quality to avoid gear sintering caused by oil shortage or contamination. Seals need to be replaced every 2000 hours to prevent leakage failures.
