Illustration 1 g00718630The oil drain for the tractor engine is located on the engine oil pan. A guard covers the oil pan.
Illustration 2 g00718631
Illustration 3 g00718632The oil filter for the tractor is on the right side of 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.
Park the machine on a level surface and engage the parking brake. Stop the engine.
The crankcase drain valve is located under the left side of the tractor.
Remove the bolt (1) in order to remove the cover plate for the crankcase drain valve. Remove the drain plug.
Allow the oil to drain into a suitable container.
Install the drain plug.
Open the access door on the right side of the engine.
Remove the oil filters (2) with a strap type wrench. See Operation and Maintenance Manual, "Oil Filter - Inspect". Discard the used oil filters properly.
Clean the filter housing base. Make sure that all of the old filter gasket is removed.
Apply a thin coat of engine oil to the gasket of the new filters.
Install the new filters by hand. When the gasket contacts the filter base, turn the filter by 270 degrees more. This will tighten the filter sufficiently.
Every new oil filter has marks which are for determining the rotation index. These marks are spaced at 90 degree increments. Use the rotation index marks as a guide for tightening the oil filter.
Clean the oil filler cap (3). Remove oil filler cap. Fill the crankcase with new oil. See Operation and Maintenance Manual, "Capacities (Refill)". Clean the oil filler cap and install the oil filler cap.
Start the engine and allow the oil to warm. Check the engine for leaks. Check the filters for leaks.
Run the engine and check dipstick (4) after the engine has been running for ten minutes. Maintain the oil between the marks on the "SAFE OPERATING RANGE" side of the dipstick. If necessary, add oil.
Close the engine access door and stop the engine.
