9. Position the crank arm (4) to engage the output
shaft (OS), and rotate it to the bottom of the output
shaft.
10. Place a clean rag over the top of the slider cylinder
(2) to prevent debris from falling into the slider
assembly during reassembly.
11. See F
. 2. Apply antiseize lubricant to the threads

of the cap screws (5*). Install the key (39), crank
arm cap (38), and cap screws (5*), oriented as
shown. While the gap-side screw is still loose,
torque the key-side screw to 210-230 ft-lb (283-310
N•m). Then torque the gap-side screw to 210-230
ft-lb (283-310 N•m).
12. Ensure that the collars (13) are in place in the cou-
pling nut (14).
13. Place a 3/4 in. wrench on the flats of the slider pis-
ton (9), to keep it from turning when you are tighten-
ing the coupling nut (14). Orient the wrench so it is
braced against one of the tie rods (3) or the pump
stand. Tighten the coupling nut (14) onto the slider
piston (9) and torque to 75-80 ft-lb (102-108 N•m).
14. Remove the rag from the slider cylinder.
15. Turn on power and jog the motor to bring the other
drive to the bottom of its stroke. Repeat procedure

16. On pumps with the sensor circuit:
a. Remove the plug from the TDC sensor port at
the back of the circuit board cavity. Clean any
excess sealant from the area.
b. Apply pipe sealant and screw the TDC sensor
(25b) into the port. Torque to 66-78 in-lb (7.4-8.8
N•m).
c. Install the strain relief (35) and the transducer
conduit into the gear housing.
d. Connect the transducer (25a) to J1 on the cir-
cuit board (25c). See F
e. Connect the IS circuit field wire to J2 and J3.
See the Electrical Schematic in the E-Flo Plus

Connect the TDC sensor (25b) to J2 on the cir-
cuit board (25c). See F
g. Install the circuit board (25c), circuit board cover
(34), and new gasket (33*).
17. Reinstall the covers (32 and 21) and screws (12*).
