Reciprocator Repair
21. Install the capscrew (3), o-ring (39) and washer
(2). Install the lockwashers (37) and nuts (36).
Torque the nuts to 28 to 32 ft-lb (36 to 43 N-m).
CAUTION
Never install the fluid tube (45) before torquing the
tie rods. Doing so could cause misalignment and
damage the reciprocator when it is operated.
22. Reinstall the fluid tube (45) and fittings (1). Torque
the fittings to 25 to 35 ft-lb (34 to 48 N-m). See the
Parts Drawing on page 20.
23. Pull the displacement rod (34) in and out to be
sure it moves easily with only a little resistance
from the rod seal.
24. To reconnect the reciprocator and pump, install the
o-ring (17). Screw the connecting rod (35) into the
displacement rod (34). Install the cotter pin (204).
Install a new copper gasket (202*). Make sure the
seal (203*) in the bottom of the adapter (43) is in
good condition. Push the cylinder up into the
adapter and engage the threads. Screw in the
pump, using a strap wrench for the final tightening.
See Fig. 12.
25. Connect the hydraulic supply and return hoses to
the fittings (5, 60).
WARNING
To reduce the risk of static sparking be sure to re-
connect the ground wire before operating the
pump.
