Drott 35 Track Drive Issues: Diagnosis and Solutions

[MikePhua]

The Drott 35 is a classic track-driven machine commonly used in construction and mining industries. Despite its robust and efficient performance, over time, users may encounter issues with its track drive system. These problems can lead to decreased performance, increased wear, and even complete system failure if left unresolved. This article explores the common issues with the Drott 35 track drive system and provides potential solutions.
Common Issues

1. Excessive Noise from the Track Drive System
   One common issue with the Drott 35’s track drive system is excessive noise during operation, especially under heavy loads or prolonged use. This noise is typically caused by worn gears, bearings, or chains within the track drive system. Excessive noise can not only be disruptive to the working environment but also serve as an indication of underlying mechanical issues that need attention.
   
2. Lack of Power in the Track Drive System
   If the machine experiences a reduction in power or struggles to move, this could be due to insufficient oil pressure in the track drive system or issues with the hydraulic pump or drive motors. A lack of power can significantly affect productivity and, if not addressed, could cause further damage to the system.
   
3. Track Slippage or Instability
   Track slippage or instability is a common issue with track-driven machines. For the Drott 35, slippage usually occurs due to inadequate track tension or poor alignment between the drive chain and gears. Over time, continuous track slippage can accelerate wear and tear on the tracks, shortening their lifespan and reducing overall machine efficiency.
   
4. Damaged or Broken Tracks
   Track damage or breakage is often a result of excessive wear or improper tensioning. The quality of the tracks and the maintenance practices will directly impact their longevity. Using inappropriate lubrication or neglecting regular inspections can contribute to premature track failure.
   
5. Hydraulic Oil Leaks
   The hydraulic system is a vital component of the Drott 35’s track drive system. If there are hydraulic oil leaks, the pressure in the system will drop, leading to poor performance in the drive system. Leaks are often caused by worn hydraulic hoses, fittings, or seals in the hydraulic pump.
   

Solutions

1. Inspect and Replace Worn Components
   For excessive noise in the track drive system, start by inspecting the gears, bearings, and chains. Replace any components that show significant wear. Additionally, check the lubrication levels to ensure the system is properly greased, as insufficient lubrication can worsen the noise and accelerate component wear.
   
2. Check Hydraulic System Pressure
   When experiencing a lack of power, it’s essential to check the hydraulic system’s pressure. Ensure that the hydraulic pump, drive motors, and associated components are functioning correctly. If the hydraulic pump or drive motors are faulty, they may need to be repaired or replaced to restore adequate power and performance.
   
3. Adjust Track Tension
   Track slippage or instability can often be resolved by adjusting the track tension. Check the tension on the tracks to ensure they are properly tight. If the track tension is too loose, adjust the tensioning device to achieve optimal tension, which will improve the interaction between the drive chain and gears and prevent slippage.
   
4. Regularly Inspect Tracks and Drive Chains
   It’s important to inspect the tracks and drive chains regularly for signs of wear and tear. Replace any damaged or worn-out tracks to prevent further damage to the system. Additionally, inspect the drive chains and gears for excessive wear and replace them as needed. Use high-quality lubricants and ensure proper lubrication to extend the life of the tracks and drive components.
   
5. Repair Hydraulic System Leaks
   Hydraulic oil leaks need to be addressed immediately. Inspect the hydraulic hoses, fittings, and seals for any signs of leakage. If a leak is found, replace the damaged components and refill the hydraulic system with the appropriate oil to restore pressure and performance.
   

Conclusion
Common issues with the Drott 35 track drive system include excessive noise, lack of power, track slippage, track damage, and hydraulic oil leaks. These problems can negatively affect machine performance and accelerate component wear if not addressed promptly. Regular inspections, timely repairs, and proper maintenance practices, such as adjusting track tension, checking hydraulic system pressure, and using high-quality lubricants, are essential to prolong the life of the track drive system and maintain the machine's efficiency.
