the packing must face down into the housing,
and the lip of the bearing must face up. Install
the o-ring (104) on the outside of the housing.

2. Install the seal (120) on the piston valve housing
at the top of the connecting rod (109). Place
the ball (110) on the seat of the housing. Install
the displacement rod (117) over the top of the
connecting rod so the holes in both parts align.
Secure with the retaining pin (118) and o-ring
(119).

3. Lubricate and place the packing housing (103) in
