5. Install the new cold start device with a new O-ring
in the injection pump fitting. Torque the cold start
device to 22 to 26 ft-lb (30 to 35 N•m).
6. Install the coolant fitting and banjo bolt on the cold
start device. Torque the banjo bolt to 16 to 18 ft-lb
(22 to 25 N•m).
7. Refill the engine cooling system and make sure to
bleed the air from the cooling system.
Engine Valve Clearance
Adjustment
The valve clearance should be adjusted every 3,000
hours.
1. Remove the rocker arm cover.
2. Remove the round cover (plug) from the timing
mark access hole on the front of the bell housing.

3. Place the engine at top dead center of the
compression stroke for the number one cylinder.
See steps a through d.

rotation (clockwise viewed from the water pump
end) until the 1-4 timing mark on the flywheel
lines up with the index mark in the timing mark
access hole.

b. Check the rocker arms on the number one
cylinder to see if they are loose.
c. If the rocker arms are loose, the engine is at top
dead center of the compression stroke for the
number one cylinder.
d. If the rocker arms are tight, the engine is at top
dead center of the exhaust stroke for the
number one cylinder. Rotate the engine 360
degrees to place the engine at top dead center
of the compression stroke for the number one
cylinder.
4. Use a feeler gauge to check the valve clearance on
both valves for the number one cylinder, the intake
valve for the number two cylinder, and the exhaust
valve for the number three cylinder. The valve
clearance for both the intake valve and the exhaust
valve should be 0.006 to 0.010 in. (0.15 to 0.25 mm).
a. Check to verify that the valve stem cap is in
good condition and is positioned squarely on
the top of the valve stem. Replace the valve
stem cap if it shows significant wear.
5. Adjust the valves if necessary by loosening the
locknut and turning the adjustment screw until the
valve clearance is correct.
