Introduction
XCMG XE2000 Mining Excavator 800366058 Travel Reducer (Original Part No.: 800366058) is a core final drive component custom-built for the 192-ton XE2000 mining hydraulic excavator. Integrating hydraulic drive, planetary reduction, and wet braking, it serves as the machine’s “travel heart,” converting hydraulic power into high-torque mechanical drive force to ensure stable travel, steering, and parking of ultra-large mining excavators under extreme conditions such as steep slopes, mud, gravel, and heavy loads.
Adopting a 3-stage planetary gear transmission structure, high-strength carburized and quenched gears, heavy-duty impact-resistant bearings, and mining-specific sealing system, this reducer matches the XE2000’s 810kW power system and 192-ton operating weight. It delivers a rated torque of over 180,000N·m and dual-speed travel (2.7km/h high speed / 2.1km/h low speed). It maintains over 93% availability in 24-hour continuous heavy-duty operations in open-pit mines, metal mines, and high-altitude extreme-cold mines, making it a key chassis part for large mining excavators to achieve efficient relocation and stable operation.

Application Scenarios and Working Condition Advantages
1. Core Application Scenarios
- Large-scale stripping and mining in open-pit coal, iron, copper, and gold mines
- Heavy-duty travel and relocation on steep slopes, muddy wetlands, and gravel roads
- Extreme mining environments: high altitude (>3000m), extreme cold (-40℃), high temperature (>50℃)
- 24-hour continuous operation, high-impact, high-dust heavy mining conditions
- Frequent repositioning and alignment for loading 100-150 ton mining trucks
2. Exclusive Working Condition Advantages
- Ultra-high Torque Capacity: 3-stage planetary drive + 20CrMnTi carburized & quenched gears (HRC58-62), load capacity increased by 50%, no slippage when climbing fully loaded (192t), adapts to ≥30° mine slopes.
- Extreme Environment Adaptability: Smooth start at -40℃, stable operation at 110℃; IP67 sealing + labyrinth dust-proof structure, resists dust, mud, and slag intrusion, prevents internal wear and contamination.
- Safe & Reliable Braking: Wet multi-disc brake + spring fail-safe design, ample braking torque, no rollaway on slopes; brake pads lubricated in oil, fast heat dissipation, low wear, 3x longer service life.
- Impact & Fatigue Resistance: Heavy-duty tapered roller bearings + reinforced planet carrier, withstands travel shocks, steering side loads, and track tension, no broken teeth, bearing seizure, or housing cracking in long-term operation.
- Efficient & Low Maintenance: Integrated design, fewer leakage points; lifetime lubrication, no frequent oil changes; annual downtime <200 hours, reduces mining operation & maintenance costs.
Common Faults, Troubleshooting and Maintenance
1. Weak Travel, Slow Speed (Single/Both Sides)
- Symptoms: Insufficient driving force, poor climbing, high gear failure, reduced efficiency
- Causes: Worn gears/bearings; hydraulic motor internal leakage; incomplete brake release; deteriorated lubricating oil
- Troubleshooting: Check travel pressure (standard 35MPa); disassemble and replace worn gears/bearings; inspect stuck brake piston; replace original gear oil.
2. Abnormal Noise & Excessive Vibration
- Symptoms: “Clicking”/“Buzzing” noise during travel, machine vibration, steering jamming
- Causes: Gear broken/pitting; bearing raceway spalling; internal impurities; misalignment
- Troubleshooting: Locate noise source; disassemble, clean, and replace worn parts; correct alignment (error <0.03mm).
3. Oil Leakage (Gear Oil/Hydraulic Oil)
- Symptoms: Oil seepage/dripping at housing joints, output shaft, motor interface, rapid oil level drop
- Causes: Aging O-rings; damaged oil seals; housing cracks; loose joints
- Troubleshooting: Replace full seal repair kit; repair cracks (weld + NDT); torque bolts to standard.
4. Travel Deviation, Uneven Steering
- Symptoms: Automatic drift in straight travel, uneven side speed, weak unilateral steering
- Causes: Single-side reducer internal leakage; uneven gear wear; incomplete brake separation; track tension difference
- Troubleshooting: Compare pressure/temperature on both sides; repair faulty reducer; adjust track tension (3-5cm sag).
5. Brake Failure, Rollaway
- Symptoms: Parking brake failure, rollaway on slopes, braking noise
- Causes: Worn brake pads; broken brake springs; insufficient hydraulic release pressure
- Troubleshooting: Replace brake pads & springs; calibrate release pressure (≥16MPa); clean brake circuit.
Key Points for Purchase and Replacement
- Verify original part number 800366058, exclusively for XCMG XE2000, avoid mismatching leading to insufficient torque, leakage, or early failure.
- Recommend full set replacement (motor + reducer) for alignment and compatibility; replace seal kit and original gear oil simultaneously.
- Strictly control alignment between output shaft and drive sprocket (error <0.05mm/m); torque bolts in cross sequence to standard (≥500N·m).
- Maintenance Schedule: Check oil level & seals every 1000 hours; inspect gear wear & bearing clearance every 3000 hours; prohibit overloading and violent pivot turns.
With original quality, ultra-high torque, and extreme durability, XCMG 800366058 Travel Reducer is the core guarantee for the XE2000’s chassis system. It helps mining customers achieve safe, efficient, and low-cost heavy-duty travel operations, making it the top choice for final drive parts of large mining excavators.
