3) Make sure that the governor run/stop lever (4, fig. 6-5) is fully rotated counterclockwise to the stop
position. Refer to paragraph 6.5.
4) Remove the flywheel locking tool and while pressing down on the top of the fuel pump tappet (2, fig.6-
6) slowly rotate the crankshaft until the fuel pump tappet (2, fig. 6-6) is felt to be at its lowest position.
5) Secure fuel pump rack setting gauge (1, fig. 6-8) to the
crankcase end face (3, fig. 6-8). Clamp the pump rack (2,
the crankcase end face (3, fig. 6-8).
6) Install the correct original shim pack on the fuel injector
pump (5, fig 6-5).
Figure 6-8.
Fuel Pump Rack Setting Gauge.
7) Insert the injector fuel pump (5, fig. 6-5) and shims gently into the crankcase making sure that the fuel
injector pump pin engages In the slot In the fuel pump rack (2, fig. 6-8).
CAUTION
It is possible that the engine will not stop when required if the pump is not rotated counterclockwise
or moves while being tightened
8) Carefully turn the injector fuel pump counterclockwise until the fuel pump rack (2,, fig 6-8) is felt
against the stop (1, fig. 6-8) and, while holding it In this position, install the clamp and nut (3 and 6 fig. 6-
5). The beveled face of the nut (6, fig. 6-5) faces down towards the clamp (3, fig 6-5). Take care to
ensure the fuel injector pump (5, fig. 6-5) does not move.
9) Torque the nut (6, fig. 6-5) to 25.0 ft. lb.
10) Rotate fuel line clamp (2, fig. 6-5) and install fuel line (1, fig. 6-5).
11) Remove the rack setting gauge (1, fig 6-8) from the crankcase end face (3, fig. 6-8) and install the
gear end cover (7, fig. 6-7), gear end oil seal (6, fig 6-7) and gasket (8, fig. 6-7) using the gear end oil
seal tool to prevent damage to the oil seal.
12) Install the crankshaft pulley, (3, fig. 6-7) and secure with bolt (4, fig. 6-7) using the flywheel locking
tool to hold the flywheel. Torque to 221 ft. lb. Remove flywheel locking tool.
c. Timing. Refer to figure 6-9.
NOTE
Fuel pump timing is only necessary if the original shims have been lost or
mixed up with those of another pump. Each pump must be timed individually
using the appropriate timing marks on the flywheel. The shims are color
coded and are available in three sizes as follows,
Green
0.003 in./0.075 mm
Slate blue
0.005 in./0. 125 mm
Black
0.010 in./0.250 mm
