Dealing with Oil on Tracks: Causes, Effects, and Solutions

[MikePhua]

Introduction
Oil on tracks is a common issue that can occur with various types of heavy machinery, especially those equipped with track systems. While tracks are essential for providing traction and stability in rugged environments, oil or grease contamination on tracks can lead to a range of operational issues. If not properly addressed, it can affect the machine’s performance, lead to costly repairs, and shorten the lifespan of the undercarriage. This article will explore the causes of oil on tracks, the potential effects on machinery, and steps you can take to prevent and resolve this issue.
Causes of Oil on Tracks
There are several reasons why oil or grease might end up on the tracks of heavy equipment. Identifying the source of the contamination is the first step toward resolving the issue.

1. Leaks from the Hydraulic System: One of the most common causes of oil on tracks is hydraulic system leaks. Hydraulic hoses, pumps, or fittings can develop cracks or wear out over time, causing hydraulic fluid to leak. When these leaks occur near the track system, the oil can spill directly onto the tracks, leading to contamination.
   
2. Leaks from the Final Drive: The final drive system, which connects the engine to the tracks, is another common source of oil leaks. If there’s a seal failure or damage in this area, it can result in oil leakage, which drips onto the track system.
   
3. Grease Leakage from the Undercarriage: Grease is used to lubricate the pins and bushings in the undercarriage of tracked equipment. Over time, the grease can leak from these components, leading to the accumulation of grease on the tracks. While grease is essential for smooth operation, excessive grease buildup can cause problems with traction.
   
4. Overfilled Lubrication Reservoirs: Sometimes, an overfilled lubrication system can result in excess oil or grease leaking onto the tracks. This may occur if the lubrication system is topped up beyond the recommended levels, causing pressure that forces excess fluid out of the system.
   
5. External Spills: In some cases, oil on tracks may come from external sources, such as accidental spills during fueling or maintenance. While these spills may not be as common, they can still contribute to the contamination of the tracks.
   

Effects of Oil on Tracks
The presence of oil or grease on the tracks can lead to several negative effects on the machine and its performance:

1. Reduced Traction: Oil on the tracks can significantly reduce the friction between the tracks and the ground, leading to poor traction. This makes it harder for the machine to move, especially in soft or muddy conditions, and can increase the risk of getting stuck.
   
2. Accelerated Wear and Tear: Oil or grease buildup on the tracks can lead to excessive wear and tear on the track components. When dirt, sand, or other debris stick to the oily surface, it creates a grinding paste that accelerates the degradation of the tracks, rollers, and undercarriage parts.
   
3. Increased Maintenance Costs: If oil on the tracks is not addressed, it can lead to more frequent maintenance requirements. The contamination can cause seals to fail more rapidly, increase the wear on moving parts, and contribute to the need for more frequent oil changes.
   
4. Safety Hazards: Excess oil or grease on the tracks can create slippery conditions, increasing the risk of accidents. Operators and maintenance personnel may be more prone to slipping when walking on the tracks or performing maintenance.
   
5. Environmental Concerns: Oil spills on the tracks not only affect the machine’s performance but can also have environmental consequences. If left untreated, oil contamination can spread to the surrounding environment, potentially causing soil and water pollution.
   

How to Prevent and Resolve Oil on Tracks
To maintain the efficiency of your equipment and extend its lifespan, it’s essential to take proactive measures to prevent and resolve oil contamination on the tracks. Here are some strategies:

1. Regularly Inspect for Leaks: Conduct regular inspections of the hydraulic system, final drive, and undercarriage components. Check for signs of oil or grease leaks, and address any issues immediately. Early detection of leaks can help prevent contamination and reduce repair costs.
   
2. Fix Leaks Promptly: If you find a leak in any of the systems, it’s crucial to repair it promptly. Replace worn seals, gaskets, or hoses, and ensure that the final drive and hydraulic systems are in good working order. If the track system is exposed to frequent oil leaks, it can lead to more significant damage.
   
3. Maintain Proper Oil and Grease Levels: Always ensure that your equipment’s oil and grease levels are within the manufacturer’s recommended specifications. Overfilling the lubrication system can cause leaks, and underfilling may lead to inadequate lubrication, both of which can cause problems for the tracks.
   
4. Clean Tracks Regularly: To prevent the buildup of oil, grease, and dirt, clean the tracks regularly. Use a pressure washer or other appropriate cleaning methods to remove any oil or grease that has accumulated on the tracks. Cleaning the tracks after each use can help maintain traction and reduce wear on the undercarriage.
   
5. Use Oil Containment Systems: Consider using oil containment systems, such as drip pans or oil catchments, during fueling or maintenance to avoid external spills. These systems can help keep oil from spilling onto the tracks and prevent contamination.
   
6. Monitor Track Tension and Wear: Proper track tension is essential for preventing excess oil or grease from leaking onto the tracks. Ensure that the tracks are correctly tensioned and regularly inspect them for signs of wear. Replace worn or damaged tracks as needed to maintain optimal performance.
   
7. Lubricate Sparingly: While lubrication is necessary for the track system, over-lubricating the components can result in excessive grease buildup on the tracks. Apply the correct amount of grease as per the manufacturer’s recommendations, and avoid over-lubricating the undercarriage.
   

Conclusion
Oil and grease contamination on tracks is an issue that can significantly impact the performance of your heavy machinery. While it’s a common problem, it’s one that can be easily managed with regular maintenance and proper attention to detail. By addressing leaks, maintaining proper fluid levels, and keeping the tracks clean, you can minimize the impact of oil contamination and ensure that your equipment remains reliable and safe to operate. Preventing oil buildup on tracks will also reduce the likelihood of excessive wear, lower maintenance costs, and extend the lifespan of your machine.
