CAT 315 Slow Tracks: Causes and Solutions

[MikePhua]

The CAT 315 is a widely used compact hydraulic excavator known for its powerful performance in various construction and earthmoving tasks. However, one issue operators may encounter is slow track movement, which can impact operational efficiency and lead to equipment wear. This article explores the common causes of slow tracks in the CAT 315 and provides solutions to address the issue.
Common Causes of Slow Tracks

1. Hydraulic System Issues
   The hydraulic system is crucial for the track drive mechanism in the CAT 315. If the hydraulic oil level is low or the oil quality deteriorates, it can reduce the power delivered to the tracks, causing them to move slowly. Additionally, a malfunctioning hydraulic pump or motor can also result in insufficient power, leading to slow track movement.
   
2. Travel Motor Failure
   The travel motor controls the movement of the tracks. If the motor fails or is severely worn, it may not provide enough power to move the tracks efficiently. Internal problems such as faulty solenoids or worn components can also lead to reduced performance, slowing down track speed.
   
3. Clogged Hydraulic Filter
   The hydraulic system's filter is responsible for removing impurities from the hydraulic oil. A clogged filter can restrict oil flow, reducing the efficiency of the hydraulic system and, in turn, causing slower track movement. Regular maintenance and timely filter changes are essential to prevent this issue.
   
4. Track Wear and Tear
   Over time, the tracks on the CAT 315 can wear down, especially in high-frequency work environments. The chains and sprockets may become worn, causing a loss of drive power and reducing track speed. This issue becomes more noticeable with prolonged usage, where the tracks lose their efficiency.
   

Solutions to Slow Track Issues

1. Check and Replace Hydraulic Oil
   The first step is to check the hydraulic oil levels and condition. If the oil is low or contaminated, it should be replaced with the proper fluid. Hydraulic oil plays a vital role in the performance of the tracks, so regular oil changes are crucial to maintaining optimal track speed.
   
2. Inspect Hydraulic Pump and Motor
   Examine the hydraulic pump and travel motor for any signs of failure. If these components are damaged or malfunctioning, they should be repaired or replaced. Ensuring that the pump and motor are in good condition will restore the required hydraulic pressure and improve track speed.
   
3. Clean or Replace Hydraulic Filters
   Regularly inspect and clean or replace the hydraulic filter. A clogged filter restricts fluid flow and reduces the system’s efficiency. Cleaning or replacing the filter can help restore fluid flow, leading to improved track performance.
   
4. Inspect Travel Motor
   Check the travel motor for any electrical or mechanical issues. If there is internal damage or failure, the motor may need to be repaired or replaced. A properly functioning travel motor ensures smooth and efficient track movement.
   
5. Check Track Components for Wear
   Inspect the track chains, sprockets, and other components for signs of wear. If any parts are worn or damaged, they should be replaced to ensure that the tracks can operate at full capacity. Replacing worn-out components helps restore the full power of the track drive system.
   

Preventive Measures

1. Regular Hydraulic System Maintenance
   To prevent hydraulic system issues, perform regular checks and maintenance. This includes changing the hydraulic oil, cleaning or replacing filters, and inspecting the hydraulic pump and motor. Proper maintenance ensures the system operates efficiently, reducing the likelihood of slow tracks.
   
2. Monitor Operating Conditions
   Avoid using the CAT 315 in overly rough or obstructed terrain, as this can accelerate track wear. Keeping the machine on more even surfaces will reduce wear and tear on the tracks, helping to maintain their performance.
   
3. Follow Proper Operating Procedures
   Operators should follow the manufacturer's recommended operating procedures. Avoiding rapid acceleration or sudden stops can reduce strain on the tracks and hydraulic system, thereby extending the lifespan of these components.
   

Conclusion
Slow tracks in the CAT 315 can be caused by issues in the hydraulic system, travel motor failure, clogged filters, or wear on the tracks themselves. By regularly maintaining the hydraulic system, replacing worn parts, and ensuring that the oil is clean and at the correct level, operators can restore the machine’s performance. Preventive maintenance and proper operational procedures are key to avoiding such issues in the future. The solutions outlined in this article should help operators get their CAT 315 tracks back to normal working condition.
