1.

With the pump on its side, tap the displacement
rod (105) with a rubber mallet to drive the priming
piston assembly out of the base (102).

2.

Hold the valve plate guide (119) with a wrench.
Use another wrench to remove the priming piston
nut (122).

3.

Remove the priming piston (121) and the valve
plate (120).

4.

Remove the clamp (118) from the base (102).
Then remove the base (102). Tap with a rubber
mallet to loosen, if needed.

5.

Remove the o-ring (123) and the spacer (113).
Tap the displacement rod again to drive the
displacement rod/priming piston rod assembly
(105/106) out of the cylinder (101).

6.

Hold the rod (106) with a wrench and remove the
priming piston guide (119).

Screw out the packing nut (117) and remove
the packing stack (116) from the intake valve
housing (115).

9.

Remove the valve plate (112). Use wrenches on
the displacement rod flats (105) and the piston
