Location of the crankcase drain valve cover
The crankcase drain valve is located behind an access cover underneath the front of the machine.
Park the machine on a level surface and engage the parking brake. Stop the engine. Note: Drain the crankcase while the oil is warm. This allows waste particles that are suspended in the oil to drain. As the oil cools, the waste particles will settle to the bottom of the crankcase. The particles will not be removed by draining the oil and the particles will recirculate in the engine lubrication system with the new oil.

Note the position of the index marks on the filter in relation to a fixed point on the filter mounting base. Note: There are rotation index marks on the engine oil filter that are spaced 90 degrees or 1/4 of a turn away from each other. When you tighten the engine oil filter, use the rotation index marks as a guide.
Tighten the oil filter according to the instructions that are printed on the filter. Use the index marks as a guide for tightening the oil filter. Note: You may need to use a Caterpillar strap wrench, or another suitable tool, in order to turn the filter to the amount that is required for final installation.
