Using gloves and minimizing contact
with the outside polished surface of
the piston, carefully place the piston
on the top of the piston insertion tool.
The serial number etched on the
inside of the piston should be towards
the top and right side up. The serial
number of the piston should be
adjacent to the serial number on the
cylinder (see Figure 49).
Slowly lift the cup and cylinder up
until the piston enters the cylinder
and the cup begins to lift the piston.
Lift the cup, piston, and cylinder off
of the spindle.
The piston-cylinder is ready to be installed in the FPG8601 platform.
6.3.6 INSTALLING THE PISTON-CYLINDER IN THE MOUNTING POST
Once the piston has been put into the cylinder (see Section 6.3.5), place the silicon O-
ring carrier assembly on the upper portion of the cylinder (lip up). The silicon O-ring is
orange and more soft than the Viton O-ring, do not confuse the two.
Place the Viton O-ring carrier inside the lower mounting post (lip down). The Viton O-ring
is a brownish color and is firm relative to the silicon O-ring.
Carefully slide the piston-cylinder assembly into the upper mounting post. Make sure
that the serial numbers on the piston-cylinder are aligned, and that the marked surfaces
are oriented upwards (see Figure 49).
Align the indexing hole of the cylinder with the hole on the indexing block.
Insert the cylinder retaining screw into the indexing block and the cylinder.
Position the holes on the piston so that they align with the gimbal ring and cylinder holes
(where the piston retaining pins will go).
Insert one piston retaining pin and thread it half way in.
Insert the remaining piston retaining pin so that it is tight.
