If you’ve recently acquired a TD25 dozer that has been sitting idle for 20 years or more, you may be wondering how to get it up and running again. Fortunately, with some careful preparation and a bit of know-how, starting a TD25 dozer after years of inactivity is entirely possible.

The first step is to inspect the dozer for any signs of damage or wear and tear. This may include checking the engine for oil leaks, inspecting the tracks for wear, and checking the hydraulic system for any leaks or damage. Any issues found during this inspection should be addressed before attempting to start the engine.

Next, it’s important to drain and replace all of the fluids in the dozer. This includes the engine oil, transmission fluid, and hydraulic fluid. Old fluids can become contaminated and lose their effectiveness over time, so it’s essential to replace them with fresh fluids to ensure optimal performance.

Once the fluids have been replaced, it’s time to turn your attention to the engine. Before attempting to start the engine, remove the spark plugs and pour a small amount of engine oil into each cylinder. This will help lubricate the cylinders and prevent any damage during the initial startup.

With the spark plugs back in place, it’s time to turn the engine over. If the battery is still functional, attempt to start the engine using the starter. If the battery is dead, you may need to jump-start the dozer or replace the battery altogether.

If the engine fails to start, it’s possible that the fuel system has become clogged or contaminated. In this case, it may be necessary to clean or replace the fuel filter and lines.

Assuming the engine starts successfully, allow it to run for a few minutes to warm up before engaging the transmission and tracks. It’s important to start slowly and cautiously, as the tracks may need to be adjusted and the brakes may need to be tested before the dozer is fully operational.

Overall, starting a TD25 dozer after 20 years of sitting is a process that requires patience, attention to detail, and a bit of mechanical know-how. With the right approach, however, it’s possible to bring these powerful machines back to life and put them to work once again.
