Replacing the Throat Seals
Refer to F

. 6 for the following instructions.
NOTE:
Replace the seals if fluid leaks excessively
through the weep tube (B). This procedure can be done
without disassembling the entire reciprocator.
1. Relieve the pressure. See Pressure Relief Proce-
dure, page 8.
2. Disconnect the reciprocator from the pump. See
Disconnecting the Reciprocator and Displacement
Pump on page 12.
3. Remove the four capscrews (46) from the bottom of
the adapter (43). Tap the adapter to loosen it, and
pull it off the bottom cap (32).
4. Remove the seals (16, 44) and guide (19) from the
top of the adapter (43).
5. Lubricate the guide (19) and install the seals and
guide in the adapter (43) one at a time in the order
shown in F
IG
. 6.
6. Reassemble. Torque the capscrews (46) to 28 to 32
ft-lbs (38 to 43 N.m). Install the displacement pump.
Follow Step 24, page 17.
NOTICE
Keep the Hydraulic System Clean
It is essential to keep the hydraulic oil system clean
and free of contaminants to reduce the risk of damag-
ing the hydraulic reciprocator. Always install a plug in
each tube fitting and on each hoe end whenever fluid
lines are disconnected to prevent contamination.
