Assemble and install the dynamic seal
carrier
1.
Inspect the dynamic seal carrier for
cleanliness and erosion damage. Erosion
damage at the innermost corner will
cause seal life to be reduced. Make sure
the guide bearing is in good condition
(the presence of cracked or loose pieces
is reason for replacement).
Clean the dynamic seal carrier as
necessary. Replace the seal carrier if
necessary.
2.
Install the rod seal as shown, with the v-
shape facing up, into the dynamic seal
carrier.
3.
Install the dynamic seal into the inner diameter of the rod seal, making sure the dynamic seal is
fully seated against the dynamic seal carrier.
Note
: Make sure the plungers are clean and free of any damage or scratches before installing the
dynamic seal carriers. The subplate adapter/seal carrier interface must be clean and free of debris.
4.
Slide the dynamic seal carrier onto the plungers until seated against the register of the subplate
adapter.
Install the high-pressure cylinder
1.
Lubricate the o-ring with o-ring lube and place it in the groove of the high-pressure cylinder.
2.
Slide the high-pressure cylinder over the plunger assembly and seat it against the seal carrier.
Position the cylinders with weep holes facing downward.
Note:
A small amount of force will be needed to seat the cylinder against the seal carrier.
Repeat for the remaining high-pressure cylinders.
Assemble the inlet poppet
1.
Place the inlet poppet spring over the shouldered side of
the inlet poppet.
2.
Apply pressure to the spring and rotate counterclockwise
until it snaps into place. Be sure the spring is firmly
attached.
Repeat for remaining inlet poppets.
