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.)
Replace the dynamic seal carrier if
necessary. Clean as 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 new high-pressure cylinder.
2.
Slide the new high-pressure cylinder over the plunger assembly and seat it against the seal carrier.
Position the cylinders with weep holes facing downward.
Note:
Slight force may be needed to seat the high-pressure cylinder to 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 the remaining inlet poppets.
