Troubleshooting Weak Tracking Issues in the PC150LC-6 Excavator

[MikePhua]

The PC150LC-6 excavator is widely used in various construction projects. However, some operators have reported weak tracking ability, which affects the machine’s performance. This article will explore the common causes of weak tracking in the PC150LC-6 and offer solutions for resolving these issues.
Possible Causes of Weak Tracking

1. Hydraulic System Issues
   

The hydraulic system is a critical component of the excavator's tracking system. Problems such as hydraulic pump failure, poor quality hydraulic oil, or leaking hoses can prevent the hydraulic system from providing enough power, leading to weak tracking.
Solutions:

• Check Hydraulic Oil
  Ensure the hydraulic oil is at the correct level. Insufficient hydraulic oil can cause low system pressure, which negatively impacts tracking performance.
  
• Inspect Hydraulic Hoses
  Look for leaks or damage to hydraulic hoses. Any leaks will result in oil loss, reducing system efficiency.
  
• Examine Hydraulic Pump and Motor
  If the hydraulic pump or motor is malfunctioning, it may not provide adequate power. Check the pump and motor for signs of failure, and replace them if necessary.
  

1. Travel Motor Problems
   

Worn or damaged travel motors can lead to weak tracking. Over time, internal components of the travel motor may fail, affecting its ability to function properly.
Solutions:

• Inspect Travel Motor
  Check the travel motor to ensure it is operating correctly. A worn-out or damaged motor may need to be replaced.
  
• Examine the Motor Drive System
  If there are issues with the drive system, it could prevent proper power transmission, affecting tracking performance. Inspect the drive system for any signs of wear or looseness.
  

1. Track Tension Issues
   

Improper track tension, whether too loose or too tight, can affect tracking performance. Loose tracks can slip, while overly tight tracks create additional resistance, both impacting the machine's efficiency.
Solutions:

• Adjust Track Tension
  Regularly check and adjust the track tension to ensure it falls within the optimal range for better tracking performance.
  

1. Track Roller System Problems
   

Any issues with the track roller system, such as damaged rollers, insufficient lubrication, or worn-out bearings, can hinder the tracking ability of the excavator.
Solutions:

• Inspect Track Rollers and Tracks
  Examine the condition of the track rollers and tracks. Ensure there is no excessive wear or damage. Regular lubrication of these components can help prevent premature wear.
  

1. Power Output Issues
   

If the engine is not providing adequate power, it will affect the performance of the tracking system. Engine problems related to fuel supply, ignition systems, or air filters can prevent the engine from delivering sufficient power.
Solutions:

• Check Engine Power Output
  Ensure the engine is providing enough power. Check the fuel supply system for smooth operation and verify that the air filter is not clogged. A properly functioning engine is necessary to support the hydraulic and travel systems.
  

Conclusion
Weak tracking in the PC150LC-6 excavator can stem from several causes, including hydraulic system failure, travel motor issues, improper track tension, problems with the track roller system, and insufficient engine power. Regular inspections and maintenance of hydraulic oil, travel motors, track tension, rollers, and engine output will help improve tracking performance and prevent work delays due to weak tracking.
