3522993 XCMG GR2605 motor grader output shaft assembly
3522993 output shaft assembly is the core power output component of construction machinery gearboxes and drive axles, responsible for smoothly transmitting gearbox torque to the drive shaft, differential or wheel mechanism. The assembly integrates the output shaft, gears, splines, bearing seats, seal journals and thrust structure. Forged from high-strength alloy steel and processed via quenching & tempering, carburizing and precision gear grinding, it features high bending strength, excellent wear resistance and high transmission accuracy, capable of withstanding heavy loads, impacts and continuous operation.
Technical Parameters
- Model: 3522993
- Type: Integral output shaft assembly
- Material: 20CrMnTi / 20CrNi2Mo alloy steel
- Heat treatment: Quenching & tempering + carburizing, hardness HRC58～62
- Structure: Involute spline + cylindrical gear
- Operating temperature: -40℃～120℃
- Precision class: Heavy-duty transmission for construction machinery
- Features: High strength, anti-fatigue, impact-resistant, wear-resistant splines, high coaxiality
Application Scenarios
Suitable for the gearbox output and drive axle input of loaders, graders, rollers, forklifts and other heavy construction machinery.
- Transmits high-torque power for heavy-duty travel and operation
- Withstands alternating loads from frequent starting, braking and steering
- Adapts to dust, mud, vibration and continuous heavy-duty working conditions
- Matches mainstream systems such as DANA and ZF
Common Faults & Troubleshooting
- Spline wear/tooth damage: Caused by poor lubrication, misalignment or overload. Replace 3522993 assembly and inspect mating splines.
- Seal journal wear & oil leakage: From scoring or corrosion. Replace the assembly and oil seal together to ensure proper sealing.
- Gear pitting & noise: Due to fatigue, oil starvation or contamination. Replace the assembly, clean housing and renew gear oil.
- Shaft bending or fracture: From severe impact, overload or misalignment. Replace immediately and correct coaxiality during installation.
