12.
Make a temporary mark on the vibration damper
in relation to the pointer on the front cover.
CAUTION
Do not use a hammer and punch to
mark a vibration damper.
13.
Turn the crankshaft in a clockwise direction
beyond the maximum indicator reading and
beyond .020 in. Now turn the crankshaft in a
counterclockwise direction until the dial indicator
is .020 in.
14.
Make a second temporary mark on the vibration
damper in relation to the pointer. Now make a
mark on the vibration damper that is one-half
the distance between the two temporary marks.
This mark is the point of most accuracy for top
center No. I piston.
15.
Turn the crankshaft in a clockwise direction
approximately 45 degrees and then turn the
crankshaft in a counterclockwise direction to the
top center mark that was made in Step 14. If
needed, adjust the dial indicator as in Step 10.
16.
Turn the crankshaft in a clockwise direction
approximately 45 degrees.
17.
Put 7M 1999 Tube Assembly (9) on No. 1
injection pump and tighten the nut. The free
end of tube assembly (9) must be in a position
above horizontal and higher than the end on the
injection pump.
18.
Disconnect the fuel line at the fuel filter. Use an
adapter to connect 5J4634 Hose Assembly (8)
to the fuel line.
19.
Disconnect the fuel return line from constant
bleed valve (1 I). Put cap (12) on the constant
bleed valve.

Put 1 gal. (4 liters) of clean fuel in the tank
assembly (10). Move the governor lever to full
FUEL-ON position. Put 15 psi (105 kPa) of air
pressure in the tank. Use the hand pump or
shop air.
NOTE
Solenoid must be activated (ignition
switch turned on) or solenoid must
be removed before governor lever
can be moved to FUEL-ON position.
CAUTION
If shop air is used, make an
adjustment to the regulator so the air
pressure in the tank is a maximum of
15 psi (105 kPa).
21.
Put pan (13) under the end of tube assembly (9)
for the fuel that comes out of the tube.
