k. Remove nuts (18) and (20), and stud (19) from bracket (15).
Remove bolt (21) from mounting plate (10).
Installation and Adjustment.
Install nut (20, FIGURE 4-6) onto stud (19) until only two or three threads are left exposed on stud shaft.
Install stud (19) and nut (20) in bracket(15) and secure with nut (18).
Install spring (17), spring retainer (16), and bracket (15) on injection pump rack lever (inside pump) with bolt (14),
Iockwasher (13), and nut (12). Torque nut (12) to 48 in-lbs (5.4 Nm).
Apply sealant (tem 20, appendix C) to both sides of gasket (11), install gasket (11) and mounting plate (10) on
injection pump with bolts (8) (threads coated with sealant (item 20, appendix C)) and Iockwashers (9). Torque bolts
(8) to 100 in ilbs (11.3 Nm).
Position clevis (6) within retention spring(7). SIotted flat end of clevis (6) is to be positioned between the two fingers
of spring (7).
Turn clevis and retention spring assembly onto shaft of actuator (3) so that side of hole (slot) in clevis (6) (closest
to the actuator face) is between 0.96 to 1.00 in. (2.43 to 2,54 cm) from face of actuator (3). Tighten nut (5) against
Apply sealant (item 20, appendix C) to both sides of gasket (4) and position gasket (4) on actuator base with one
bolt (1) and one Iockwasher (2) in upper hole of actuator.
Polarity of power to the actuator is not important.
Connect 5 ohm, 25 watt resistor in series with one pin of P10 connector and ground. Connect a jumper wire from
other pin of P10 connector to positive battery terminal.
Connect negative battery cable to energize and extend actuator shaft.
Insert medium size screwdriver through access hole at top of injection pump housing and hold injection pump rack
fully toward rear of engine.
With actuator(3) energized insert actuator shaft through hole in mounting plate (10) at a slight upward angle. Move
shaft inward until lower finger of retention spring (7) compresses sufficiently allowing top of stud (19) to align itself
under slot of clevis (6).
Use tip of screwdriver that held fuel pump rack to compress upper finger of retention spring (7) so that clevis (6)
can drop down on stud (19).
Deenergize actuator (3).
Secure actuator (3) to mounting plate (10) with allen head screws (1) (threads coated with sealant (item 20, appen-
dix C)) and Iockwashers (2). Torque to 100 in Ibs (11.3 Nm).
While Iooking through rear injection pump access plug hole, energize and reenergize actuator a few times to insure
there is no binding. Lubricate actuator shaft with oil (item 11, appendix C).
Using rear injection pump access hole, fill pump housing with engine oil (TABLE 2-3) to a level even with bottom
of hole for bolt (21).
Install rear injection pump access plug in top of injection pump and bolt (21) in mounting plate (10).
Remove jumper wires and connect P10 connector to engine harness.
Connect battery cable. Close access doors.
