1. Engine Oil Drain Plug
2. O-ring Seal
3. Engine Oil Filter
To change the engine oil and filter:
1. Run the engine at idle for about
20 seconds to return all of the oil back
into the dry sump oil tank.
2. Turn the engine off prior to draining
the oil.
3. Remove the engine oil drain plug from
the bottom of the engine oil pan. Drain
plug removal will let the oil drain from
the external oil tank and residual oil
from the crankcase sump. Allow the oil
to drain.
4. Remove the engine oil filter and allow
the oil to drain.
5. Inspect the drain plug O-ring seal and
replace if it is damaged. Reinstall the
drain plug into the oil pan and tighten it
to 25 N.m (18 lb ft).
6. Replace the oil filter and tighten it
three-quarters to one turn after the
gasket makes contact. See Maintenance
Replacement Parts 0 296 for the correct
filter.
7. Remove the oil fill cap from the external
engine oil tank.
Add oil to the oil tank through the
opening in the fill tube. See Capacities
and Specifications 0 300.
8. Install the oil fill cap and insert the
dipstick, if removed.
Warning
To help avoid personal injury and/or
engine damage, always install the engine
oil dipstick and oil fill cap until fully
seated to a stop. If not fully seated, oil
could escape on to hot exhaust parts and
cause a fire.
