NOTE
When installing the snap ring, it must be in-
stalled with the tapered side away from the pis-
ton so that the taper is visible after installation.
The gap between the ends of the installed snap
ring should be measured to be sure the ring is
seated. The minimum permissible gap is
2
%
4
inch. Be sure the snap ring does not restrict any
part of the ports in the end of the piston rod.

and slide into position in assembly, as shown in
Figure 41. Using care not to damage the "0"
rings, slide upper piston rod over the valve rod,
aligning the piston pin hole in the piston assem-
bly with the hole in the upper piston rod, as
shown in Figure 42. Lubricate a new piston pin
" 0 " ring with Lubriplate and install on piston
pin, as shown in Figure 43. With the piston pin
holes aligned in both the piston and upper pis-
ton rod, position piston pin (tapered end first)
in position. Use a % inch punch and hammer,
tap lightly until piston pin is flush or slightly
below bottom of piston ring groove (Figure 43).
If piston pin is too high in groove, piston ring
will not properly seal. This will cause unequal
pressure when valve is centered in piston.
Using snap ring pliers, install the upper pis-
ton rod snap ring. Use the same precautions
and specifications as previously used in position-
ing the lower piston rod snap ring. Select snap
ring of sufficient thickness to prevent turning of
snap ring after it is installed. If it is too loose,
the piston will move with relation to the piston
