5-40. INJECTION PUMP TESTING, REPLACEMENT, AND ADJUSTMENT .-Continued
(4) Install the fuel delivery sight onto the injection pump fitting (9).
NOTE
It may be necessary to rotate the flywheel several turns in order to get fuel to become visible in
the fuel delivery sight.
(5) Slowly rotate engine flywheel (11) clockwise until the column of diesel fuel inside the fuel delivery sight
starts to move. This indicates the start of static injection.
(6) The reference mark (27) on shroud (28) should match the static injection point (29) (middle dot) punched
onto the flywheel (11).
NOTE
Each 0.003 inch (0.1 mm) gasket inserted beneath the injection pump correspond to 1.38 of
rotation on the flywheel.
(7) If the static injection point (29) is to the left (counterclockwise) side of re erence mark (27), the timing is too
f
advanced and the injection pump (12) must be removed and installed with additional gasket(s) (23).
(8) If the static injection point (29) is to the right (clockwise) side of reference mark (27), the timing is too
retarded and the injection pump (12) must be removed and installed with fewer gasket(s) (23).
(9) Position manual shut down lever (10) fully to the right (clockwise).
(10) Be sure manual shut down lever (10) is fully to the right then install new gasket (1 ), cover (17), and two
8
screws (16).
(11) Pass wire (30) through manual shut down lever (10) and clamp (15). Position manual shut down lever fully
to the left then slide clamp against lever and tighten screw (14).
CAUTION
Always use two wrenches when tightening the fuel pipe to prevent turning the nozzle or injection
pump fitting.
(12) Install fuel pipe (8) and tighten two flare nuts (7). Torque flare nuts to between 11 and 18 ft-lb (15 and 25
Nm).
(13) Install new gasket (6), cover (5), and three screws (4).
(14) Install cylinder casing (3), flat washer (2), and screw (1).
