(20) Place pump in horizontal position with controlunit bore (36 ) facing up.(21 ) Center the plunger sleeve (34) in the controlunit bore (36 ). Position plunger sleeve pin (5) so thatthe flats align with the groove in the control sleeve (34)and the electric pencil mark (dot ) faces the top of thepump.(22 ) Insert control unit assembly (4) into housing(6), pressing gently until control unit seats.Do not use force. If flange is not seated onpump housing, rotate arm both ways withfinger pressure pushing control unit in.NOTERotate the control unit lever through a 360°arc to make certain that the control unit as-sembly is correctly installed. Failure to ro-tate 360” indicates that the plunger sleeve pin(5) is not engaging the plunger sleeve slot.(23) Install control unit assembly retaining plate,as shown in figure 7-39 using two tab washers and twoscrews. Torque screws to 20-25 inch-pounds and bendlocking tabs over screws.NOTEIf control unit will not seat, pull it out and re-peat steps (20) through (22 ).Figure 7-40.

Test.(1) Turn pump upside down and depress tappetwith thumb. Tappet should recede 1/16” into face gear(figure 7-40). If tappet cannot be depressed 1/16” intoface gear, plunger sleeve pin (5, figure 7-34 ) is improp-erly aligned. Disassembly pump and re-align pin.(2) Remove the overflow valve assembly from thefuel outlet hole in the pump housing. Install a 1/4” pipeplug into the fuel outlet hole.(3) Secure the pump close to a Nozzle Test Stand.(4) Cap outlet ports (see figure 7-41 ).(5) Install C-clamp on injection pumps as shownin figure 7-41 to retain face gear.(6) Align holes in face gear and housing (see fig-ure 7-41).(7) Connect the Nozzle Test Stand to the fuel in-let hole in the pump housing.Change 47-37
