a. Fill a container with kerosene and place the

valve lifter into the container as shown.
Pump the plunger side of the valve lifter with
a press a number of times to let in kero-
sene.

CAUTION:

• Do not pump the valve lifter excessively.

b. Install the valve lifter into the engine.

CAUTION:

Be sure to install the valve lifter in its
appropriate position.

c. Start the engine and warm it up.
d. Stop the engine.
e. Remove the camshaft sprocket cover.
f. Rotate the camshaft until the punch mark 

1

on the camshaft driven gear aligns with the
punch mark on the camshaft drive gear as
shown. This is the condition in which piston
#1 is at top dead center (TDC).

NOTE:

The crankshaft can be rotated smoothly when
the spark plugs are removed.

WARNING

Be careful since the engine is hot.

g. With piston #1 at TDC, count the indicated

number of gear teeth and place marks 

2

through 

5

 on the camshaft driven gear as

shown. When these marks align between
the centers of the camshaft drive and driven
gears, the corresponding valve lifter is at its
highest point.
