Removing and Replacing the Engine Oil
Tools and Supplies Needed
•
SAE 30 HD Oil
•
12mm Wrench
•
Suitable container for used oil
•
Rags
Note: Drain the oil when the engine is warm. Warm oil drains quicker and more
completely.
1.
Position a suitable oil receptacle under the engine oil Drain Plug and
remove the Engine Oil Check/Fill Cap (Figure 41a or 41b).
2.
Remove the Oil Drain Plug from the Engine Block. Allow the used oil to
drain completely, and then replace the Oil Drain Plug.
3.
Replace the engine oil using SAE 30 HD oil (see "Adding Engine Oil and
Gasoline" in Chapter 2 for instructions on adding oil).
4.
Reattach the spark plug wire.
Note: Be sure to use environmentally safe procedures when disposing of the used oil.
