Lubricate two valve rod "0" rings with Lu-
briplate and install one in each end of upper
piston rod (Fig. 26). Make certain rings are
seated properly. Lubricate two large "0" rings
and install one on upper piston rod and the
other on lower piston rod, making sure rings
are seated properly in grooves.
Lubricate valve assembly with Lubriplate
and slide into position in upper piston rod.
Work with care to avoid damaging "0" rings.
Align piston pin hole in upper piston rod (Fig.
27). Install upper piston rod and valve assem-
bly into piston. Lubricate and install a new "O"
ring on piston (Fig. 28).

tered in piston.
Install upper piston rod snap ring. Follow
same precautions and specifications, as pre-
viously used, in positioning lower piston rod
snap ring. Select snap ring of sufficient thick-
ness to prevent turning of snap ring after it is
installed. If it is too loose, the piston will move
with relation to piston rod and adjustment of
control valve cannot be maintained. Place a
new upper piston rod seal on driver (lip of
seal facing tool). Lubricate seal with Lubri-
plate and drive into position in housing head
(Fig. 29).

If early type driver*with tapered end is used,
remove the seal garter spring before installing
