Engine Maintenance

1. Remove the injection line for the number one
cylinder from the delivery valve on the
injection pump and from the injection nozzle.
NOTE: The number one cylinder is the
cylinder at the flywheel end of the engine.
2. Remove the delivery valve spring for the
number 1 cylinder by removing the delivery
valve holder and the delivery valve spring,
and then reinstalling the delivery valve holder
without the delivery valve spring in place.
3. Remove the cylinder head cover (valve
cover/intake manifold assembly).
4. Place the engine at top dead center of the
compression stroke for the number one
cylinder. Refer to steps a through d.
a. Rotate the engine in the normal direction
of rotation (clockwise viewed from the
water pump end) until the number one
TDC mark on the flywheel lines up with
the timing mark on the starter mounting
plate.
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.
5. Disconnect the 8S wire from the starter
solenoid to prevent the engine from cranking
when the unit is turned On.
6. Energize the fuel solenoid and the fuel pump
by turning the unit On (or using the Service
Test Mode, see the appropriate
Microprocessor Diagnostic Manual).
7. Rotate the engine backwards
(counterclockwise viewed from the water
pump end) until the injection timing mark is
positioned about 1.0 in. (25 mm) below the
timing mark on the starter mounting plate.
8. Use a clean towel to remove the fuel from the
top end of the delivery valve holder.

being rotated.
