(1) Drain Plug
Remove magnetic drain plug (1) from the bottom of the transmission. Allow the oil to drain into a suitable container.
Inspect the magnetic drain plug for large particles of debris. An excessive amount of debris may be an indication of possible failure. Discolored oil or oil with an odor requires a careful analysis of S O S results. If large particles are found, consult your Caterpillar dealer for further analysis and additional guidance.
After the oil has drained from the transmission case, clean the drain plug before reinstalling the drain plug. Tighten the drain plug to 90 13 N m (66 10 lb ft).
