The Tak TL145 is a widely used compact track loader known for its efficient performance on various job sites. However, like many heavy machines, it can face common technical issues over time. One such problem that some users encounter is the loss of 2nd speed functionality. This article shares the experience of a user who faced this issue and the steps taken to diagnose and resolve the problem.
Symptoms of the Issue
The user noticed that their Tak TL145 was unable to engage 2nd speed. Normally, the machine allows operators to switch between 1st and 2nd gears for different speed settings, but after the issue occurred, the second gear wouldn't engage no matter how the controls were adjusted. This limitation resulted in the machine being stuck in low speed, significantly affecting work efficiency and productivity.
Diagnosis Process
The first step involved checking the hydraulic and transmission systems to rule out the most common causes of such issues. After thorough inspection, it was found that the issue likely stemmed from a malfunction within the transmission's hydraulic valve or control system. Additionally, the quality and level of the hydraulic fluid were considered possible contributing factors. To further pinpoint the issue, the user decided to conduct a more detailed system examination.
Solution
Upon deeper investigation, it was determined that the problem was due to a stuck hydraulic valve inside the transmission. The user replaced the faulty valve and performed a full system flush to ensure smooth oil flow throughout the hydraulic system. They also inspected the hydraulic oil quality and found no contaminants or impurities. After replacing and cleaning the components, the 2nd speed function was restored and the machine was back to normal operation.
Conclusion
The loss of 2nd speed on the Tak TL145 was successfully resolved by replacing the stuck hydraulic valve and cleaning the hydraulic system. The root cause of the issue was traced to a malfunctioning valve within the transmission, which prevented the engagement of the second gear. Regular maintenance, including checking and replacing hydraulic fluid, is key to preventing such issues and ensuring the proper functioning of heavy equipment.
