done without disassembling the entire reciprocator.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 9.
1. Relieve the pressure.
2. Disconnect the reciprocator from the pump. See
the procedure on page 13.

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).
NOTE: Items 16 and 44 are included in the
Reciprocator Repair Kit, 223426.

CAUTION
Keep The Hydraulic System Clean

and free of contaminants to reduce the risk of dam-
aging the hydraulic reciprocator. Always install a
plug in each tube fitting and on each hose end
whenever fluid lines are disconnected to prevent
contamination.
