Do I need to replace the lubricating oil after drying the DBY200-12-2 reducer

After the DBY200-12-2 reducer is dried, the lubricating oil must be replaced, which is a key step to avoid residual moisture and impurities affecting equipment performance.
Core reasons

After being dampened, the original lubricating oil has become emulsified, contains water, or mixed with impurities. Even if dried, its lubricating performance cannot be restored, and continued use will exacerbate gear and bearing wear.

During the drying process, residual oil may deteriorate due to high temperature oxidation, resulting in sludge and carbon deposits, which affect transmission efficiency and increase the risk of component corrosion.

New lubricating oil can form a complete oil film, completely isolate residual moisture, and clean small impurities that may remain after drying, protecting the meshing accuracy of hard toothed gears.

Additional precautions

When replacing, it is necessary to use extreme pressure industrial gear oil that is suitable for the working conditions, with a viscosity grade according to the equipment manual requirements (usually 220 # or 320 #).

Before injecting new oil, it is necessary to ensure that the oil drain port and the interior of the fuel tank are clean to avoid impurities from entering; The oil level should reach the rated scale and should not be too much or too little.

After replacement, start the gearbox and run it without load for 30 minutes. Check if the oil circulation is normal and if there is any leakage at the sealing point.
