Installation Procedure
Oil and Oil Filter
1. A drain plug is located on the service side of the oil
sump, opposite the starter.
2. Remove one oil drain plug and the oil fill cap/
dipstick. Aim the drain tube into catch basin and
open the valve near the oil sump. Allow ample time
for complete drainage.
3. Close the valve and place the hose back in clip on
bulkhead wall.
4. Remove the old filter and wipe off the adapter/base
on the engine.
5. Place a new replacement filter in a shallow pan with
the open end up. Pour new oil (provided) in through
the threaded center hole. Stop pouring when the oil
reaches the bottom of threads. Allow a minute or
two for the oil to be absorbed by the filter material.
6. Apply a thin film of clean oil to the rubber gasket on
the new oil filter.
7. Install new oil filter. Hand tighten filter clockwise
until the rubber gasket contacts the adapter, then
tighten the filter an additional 3/4--1 turn.
8. Fill the crankcase with the new oil to the F or FULL
mark on the dipstick. Always check the level with
the dipstick before adding more oil. Never operate
the engine with the oil level below the L or ADD
mark, or above the F or FULL mark. See Figure 2.

10. Reconnect the negative battery cable and spark
plug lead(s). Test run the engine, check for leaks
and recheck oil level.
Spark Plug
1. Before removing the spark plug(s), clean or blow
out the area around the base of the plug(s) to keep
dirt and debris out of the engine. Wear suitable eye
protection, as required.
2. Using a 5/8 in. spark plug socket, remove and
discard the old spark plug(s).
3. Check and set the gap of the new spark plug(s)
using a wire feeler gauge. See Figure 4. Adjust the
gap by carefully bending the ground electrode.
See Figure 3.
4. Install the new spark plug(s) and torque as shown
in Figure 4.
