valves in the system, having a waste container
ready to catch drainage. Leave open until you are
ready to pressurize system again.
4. Check that pressure gauges on fluid supply and
return lines read zero. If gauges do not read zero,
determine cause and carefully relieve pressure by
VERY SLOWLY loosening a fitting. Clear obstruction before pressurizing system again.

1. Follow Pressure Relief Procedure, page 2.
2. Supply the appropriate flushing material to the system.
3. Set pump to lowest possible fluid pressure, and start
the pump.
4. Flush long enough to thoroughly clean the system.

1. Flush the pump, see page 3.
2. Jog the motor to bring the lower on the side being
repaired to the bottom of its stroke. This provides
access to the coupling nut (14).

6. Repeat steps 2-5 for the other lower.
IG. 1. Place a 3/4 in. wrench on the slider pis-
ton (9) flats (just above the coupling nut), to keep
the slider piston/connecting rod from turning when
you are loosening the coupling nut (14). Orient the
wrench so it is braced against one of the tie rods (3).
Applying excessive force to the slider piston/connecting rod can shorten the life of the lower pin
bearing.

Kit Installation
Reassembly
1. See FIG. 2. Install the coupling nut (14) on the
lower’s piston rod (PR).
2. 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) onto the tie rods handtight.
3. Assemble the inlet and outlet manifolds (17) to the
lower, using new gaskets (16) and clamps (18).
Torque the clamps (18) to 15-20 ft-lb (21-27 N•m).
4. Torque the locknuts (15) to 50-60 ft-lb (68-80 N•m).
5. At the outlet manifold (17):
a. On pumps with a sensor circuit: Install a new
black o-ring (41) on the transducer (25a). 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).
b. On pumps without a sensor circuit: Install a
black o-ring (41) on the plug (45). Screw the
plug into the outlet manifold (17) and torque to
15-20 ft-lb (21-27 N•m).
6. Install a black o-ring (41) on the plug (45). Screw the
plug into the inlet manifold (17) and torque to 15-20
ft-lb (21-27 N•m).
7. Ensure that the collars (13) are in place in the coupling nut (14).
8. Place a 3/4 in. wrench on the flats of the slider piston (9), to keep it from turning when you are tightening the coupling nut (14). Orient the wrench so it is
braced against one of the tie rods (3) or pump
stand. Tighten the coupling nut (14) onto the slider
piston (9) and torque to 75-80 ft-lb (102-108 N•m).
9. Turn on power and jog the motor to bring the other
drive to the bottom of its stroke. Repeat procedure
to connect the other lower.
NOTE: Update the drive software to reflect the change
in size of the lowers. See manual 311596.
10. 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 reinstalling in the system.
