2. Loosen the locking screw (3). Rotate the spacer
(4) in order to allow the locking screw (3) to tighten
against the shaft of the fuel injection pump. Rotate
the fuel injection pump gear in a counterclockwise
direction in order to remove the backlash. Tighten
the locking screw (3) to a torque of 13 N·m
(9.6 lb ft).
Note: The locking screw (3) must be tightened in
order to prevent the shaft of the fuel injection pump
from rotating. The shaft of the fuel injection pump
must not be rotated after the fuel injection pump has
been removed from the engine.
Note: Put identification marks on all fuel hose
assemblies and on all tube assemblies for installation
purposes. After being disconnected, plug all fuel
hose assemblies and plug all tube assemblies with
suitable plastic plugs. Also install dust caps on all
of the connectors on the fuel injection pump. This
helps prevent fluid loss, and this helps to keep
contaminants from entering the system.
3. Disconnect the fuel return line (5).
4. Disconnect the fuel line (1).
5. Disconnect the harness assembly from the fuel
shutoff solenoid (2).
