Application Scenarios

• Realize differential rotation of left and right wheels for flexible steering without slipping
• Transmit high torque for heavy-load digging, climbing and compacting working conditions
• Resist mud, dust, severe vibration and impact loads on construction sites
• Match mainstream drive axle assemblies such as DANA, ZF, etc.

Common Faults & Troubleshooting

• Abnormal noise and gear clashing: Caused by gear wear, poor lubrication or abnormal backlash. Replace 3349413 differential assembly and readjust clearance.
• Oil leakage: Seal failure at housing joint surface. Replace sealing gaskets and tighten bolts to specified torque.
• Running deviation and uneven power transmission: Caused by gear wear or poor side gear fit. Replace the assembly and inspect axles and bearings.
• Overheating: Caused by insufficient oil, washer wear or excessive tightness. Replace the assembly, clean oil passages and change gear oil.
