Reassembly
1. See F
. 3. Install the two new bearings (8*) on the
IG
slider piston (9). The joints between the bearings
must align with the pin hole (PH) in the slider piston.
2. Screw the slider cylinder (2*) into the gear reducer
(1). Torque to 15-20 ft-lb (21-27 N•m). Install the set-
screw (31*).Torque to 30-35 in-lb (3.4-3.9 N•m).
3. Install two screws (12) and the cover (32 is shown;
use 21 on the motor side).
4. Install the coupling nut (14) on the lower's piston rod
(PR).
5. Orient the lower (22) to the gear reducer (GR) as
shown. Position the lower on the tie rods (3). Screw
the tie rod locknuts (15*) inclulded in the kit onto the
tie rods handtight.
6. Assemble the inlet and outlet manifolds (17) to the
lower, using new gaskets (16*). Torque the clamps
(18) to 15-20 ft-lb (21-27 N•m).
7. Torque the locknuts (15*) to 50-60 ft-lb (68-80 N•m).
4
8. Install a new black o-ring (41*) on the transducer
(25a).
9. Insert the transducer into the outlet manifold (17).
Torque the adapter (42) first, then the nut (43) to
15-20 ft-lb (21-27 N•m).
10. Ensure that the collars (13) are in place in the cou-
pling nut (14).
11. 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).
12. Turn on power and jog the motor to repeat proce-
dure for the other lower.
13. Flush and test the pump before reinstalling it in the
system. Connect hoses and flush the pump. While it
is pressurized, check for smooth operation and
leaks. Adjust or repair as necessary before reinstall-
ing in the system.
