Cub Cadet 8404 manual Changing Engine Oil and Filter

Changing Engine Oil and Filter

The engine oil and oil filter (located on the right/front of the engine) should be changed after the first 50 hours of operation, then at 100 hours and every 100 hours thereafter. Refer to the LUBRICATION TABLE for the quantity and type of oil needed.

WARNING: Because the engine is run prior to draining the oil, the engine may be hot. Use caution to avoid burning yourself on engine surfaces.

Run the engine for a few minutes to allow the oil in the crankcase to warm up. Warm oil will flow more freely and carry away more engine impurities. Use care to avoid burns from hot oil. While the engine oil is warm, proceed as follows:

•Place the tractor on a level surface and engage the parking brake. Stop the tractor engine and remove the ignition key.

•Clean around the base of the oil filter, the oil filler cap, and the dipstick to prevent debris from entering the crankcase.

•Remove the dipstick and oil fill cap from the engine. Refer to Figure 56 and Figure 57.

•Locate the engine drain plugs on the bottom of the engine. Place a suitable container below the drain plugs to collect the old oil. See Figure 58.

•Turn the drain plugs counter-clockwise to remove from the engine.

•Allow the old oil to completely drain from the engine crankcase into the container below.

•Move the drain pan beneath the filter, then remove the filter by turning it counterclockwise using a filter wrench to loosen. See Figure 59.

•Reinstall the drain plugs in the engine and clean up any residual oil.

•Apply a light coating of clean oil on the gasket of the new oil filter. Thread the filter onto the engine and tighten by hand.

•Refill the crankcase to the "FULL" mark on the dipstick with the appropriate type oil.

•Reinstall the oil fill cap and dipstick.

•Start and run the engine for a few minutes to check that the engine oil pressure light goes out and to circulate oil throughout the engine. Stop the engine and check for leaks at the oil filter and drain plug.

•Wait 3 minutes and re-check the oil level. If needed, add oil to bring the oil level up to the "FULL" mark.

WARNING: Never overfill the engine crankcase. For best results, fill to the “FULL” mark on the dipstick as opposed to adding a given quantity of oil. Always check the level on the dipstick before adding more oil.

Dispose of used oil in an environmentally safe manner. If necessary, contact your area EPA office for proper disposal procedures and recycling center locations.

IMPORTANT: The oil fill cap and dipstick must always be installed securely in place when the engine is running. Severe engine damage could result from failure to do so.
