intake valve assembly. Use a new gasket (202*).

5.

Remove the packing nut (216) and the plug (205).
See Fig. 30.

6.

Use a plastic mallet to tap the piston rod (224)
down. Pull the rod out from the bottom of the
cylinder (219). See Fig. 30.

7.

Remove the throat packings and the glands (B).
See Fig. 31.

8.

Clamp the flats of the piston rod (224) in a vise.
Loosen the nut (211). Unscrew the piston valve
