This article covers the common transmission problems on the Terex 82-40 and the steps to troubleshoot them.
Common Transmission Problems
- Shifting Issues
One of the most common transmission problems is difficulty in shifting. This can occur when the transmission fluid is low, or the fluid has become contaminated. Additionally, issues with the shift linkage or transmission solenoid can cause shifting problems.
- Loss of Power
A loss of power while operating the machine may be caused by problems within the transmission, such as a malfunctioning pump, worn-out gears, or damaged seals. It can also happen if there is a lack of proper fluid pressure, which may indicate a pump failure.
- Overheating
Transmission overheating can happen due to insufficient cooling, high operating temperatures, or a clogged transmission cooler. This can lead to premature wear on transmission components, causing further damage.
- Fluid Leaks
Leaking transmission fluid is another sign of potential issues in the Terex 82-40’s transmission. Leaks often occur at seals or gaskets, and if left unchecked, they can lead to low fluid levels, which can cause shifting problems and power loss.
- Check the Fluid Level and Quality
The first step in diagnosing transmission issues is to inspect the transmission fluid. Ensure the fluid is at the correct level and check its quality. If the fluid is dirty or smells burnt, it may need to be replaced.
- Inspect the Shift Linkage
If the transmission is having trouble shifting, check the shift linkage for any signs of wear or misalignment. A damaged or worn linkage may prevent proper engagement of gears. Also, check the transmission solenoid for proper functionality.
- Test the Pump and Pressure
A failing pump or inadequate fluid pressure can cause power loss and shifting issues. To test the pump, you may need to use a pressure gauge to ensure the pressure is within specifications. If the pressure is too low, the pump may need to be replaced.
- Check for Fluid Leaks
Inspect the transmission system for any visible fluid leaks. Common leak points include seals, gaskets, and hoses. If leaks are found, replace the damaged parts to prevent further fluid loss.
- Inspect the Transmission Cooler
Overheating can be avoided by checking the transmission cooler. Make sure the cooler is not clogged and is functioning properly. A malfunctioning cooler can lead to excessive heat buildup in the transmission, which accelerates wear and tear.
Troubleshooting the Terex 82-40 transmission requires a systematic approach, starting with checking the fluid, followed by inspecting key components such as the shift linkage, pump, and cooler. By addressing the root causes of shifting issues, power loss, and overheating, operators can keep the transmission in good working condition, minimizing downtime and extending the life of the machine.
