Assemble the end cap
1. Lightly lubricate the new check valve o-ring with
o-ring lube and install it into the grooves on the
check valve body.
2. Lightly lubricate the end cap o-ring with o-ring lube
and install it in the groove in the inner diameter of
the end cap.
3. With the outlet cage facing the end cap, insert the
check valve body into the end cap.
Repeat for the remaining end caps
Check plunger torque
1. Install the plunger nut tool over the plunger and
plunger nut. Use a torque wrench to torque the
plunger nut to 20 ft-lb (27 N-m).
2. Rotate the pulley to fully extend the next plunger to
be checked.
Repeat steps for the remaining plungers. When finished,
wipe off dirt and grease from all plungers.
Rebuild the subplate adapter
1. Make sure the tie rods are firmly seated in the
subplate.
Note: Hand tight is sufficient.
2. With the v-shaped face towards the subplate
adapter, install the new rod seal in the counterbore
of the subplate adapter.
3. Place the new spacer in the counterbore with the
chamfered side down (toward the newly-installed
seal).
4. Secure the rod seal and spacer with the new snap
ring.
5. Lubricate and install the two new o-rings onto the
adapter, and slide the adapter over the plunger until
it engages the counterbore of the subplate.
Repeat Steps 1–5 for the remaining subplate adapters.
