Position plunger sleeve pin (5) so that theflats align with the groove in the control sleeve (34) andthe electric pencil mark (dot) faces the top of the pump.(22) Insert control unit assembly (4) into housing(6), pressing gently until control unit seats.Do not use force. If flange is not seated on pumphousing, rotate arm both ways with finger pres-sure control unit in.NOTERotate the control unit lever through a 360° arcto make certain that the control unit assemblyis correctly installed. Failure to rotate 360°indicates that the plunger sleeve pin (5) is notengaging the plunger sleeve slot.(23 ) Install control unit assembly retaining plate, asshown 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. Checking Plunger Sleeve AlignmentFigure 7-41. Pressure Testing Injection Pumpe. 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 improperlyaligned. Disassemble 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 shown infigure 7-41 to retain face gear.(6) Align holes in face gear and housing (see figure7-41).(7) Connect the Nozzle Test Stand to the fuel inlethole in the pump housing.7-37
