Final drives — Spare parts for mini excavators and construction machinery

• Compact, rugged design: Ideal for mini and midi excavators, our final drives combine a small footprint with high load capacity.
• Guaranteed compatibility: Optimized to work with Trabber rubber tracks for a perfect interface and superior combined performance.
• High hydraulic efficiency: Quality motors and gearboxes delivering excellent output torque and smooth transmission.
• Advanced sealing systems: Protect internal components from dust, water and mud, extending service life.
• Consistent performance: Built with high-performance materials and rigorous quality control processes.

Final drive fault identification

Detecting issues early prevents major failures in the traction system. Common symptoms include:

• Power loss: If the machine loses traction or jerks while traveling, internal wear in gears or hydraulic valves may be present.
• Oil leaks: Visible leaks on the housing indicate possible damage to seals or the final drive shaft.
• Excessive noise: Metallic noises or unusual vibration can signal damaged bearings or misaligned gears.

Final drive maintenance

Preventive maintenance is key to maximizing final drive life. Main recommendations:

• Oil checks: Verify oil level and condition every 100–150 hours. Replace after the first 250 hours and then every 500–800 hours depending on use.
• Seal inspection: Ensure there are no leaks. Replace seals if moisture or oil traces are found on the housing.
• Rubber track tension control: Incorrect tension can negatively affect final drives. Check and adjust periodically.

• High-performance gearbox: Precision internal transmission with hardened gears for wear resistance in demanding conditions.
• Efficient hydraulic motor: Optimized flow and pressure control for steady traction, even in intermittent or irregular work.
• Integrated parking brake: Automatic system built into the final drive for safe holding when the machine is stopped.
• Premium seals and bearings: Dual sealing technology and high-load bearings protected against dust, mud and water.
• Two-speed configuration: Available models with automatic speed shift by load, easing work on different ground conditions.
• Multi-brand compatibility: Broad coverage for mini excavators from 1 t to 10 t and midi excavators up to 15 t, with OEM-equivalent references.

• Oil level control: A dropping level or presence of metal particles indicates internal wear. Check and change oil at the recommended intervals.
• Seal condition review: Visible leaks or oil traces externally can compromise operation and lead to major failures.
• Noise and vibration inspection: Metallic sounds, abnormal vibration or traction loss clearly signal internal wear or misalignment.
• Correct rubber track tension: Over-tension overloads final drive bearings; low tension causes irregular movement and shocks. Adjust per manufacturer specs.
• Operating conditions: Abrasive environments or heavy water/mud exposure increase wear risk. Clean regularly and shorten inspection intervals.
• Records and traceability: Keeping service logs helps anticipate failure and plan component replacement without compromising machine uptime.
