down.
b) If a press is not available, use the head of a 5/16” x 4”
bolt head to drive the seals out.
NOTE: Reverse pliers may also be used to
remove the seal.
c) Separate the stainless steel washer from the adapter.
d) Place the adapter on a block or packing case and
drive out the low-pressure seal using a socket sized
to fi t.
4) Reassembly of Low-pressure Seal:
a) Examine the O-Ring on the adapter and replace it if it
is cut or worn.
b) Lubricate inside of the adapter, insert new pre-
greased lo-pressure seal into adapter with garter
spring facing up and press squarely into position.
c) With crankcase side of the inlet manifold facing up,
insert washer into seal chamber.
d) Lubricate inside of seal chamber and outer surface of
adapter O-Ring.
e) Insert lo-pressure seal assembly with garter spring
facing down and press squarely into position.
f) Servicing the plungers:
1) Disassembly:
a) Remove the seal retainers from the ceramic plungers.
b) Remove the inner collar from the front of the seal
retainer.
c) Remove the used wick and install new wick.
NOTE: If replacing plungers, do not lubricate
the new wick. Allow grease from new seal
to lubricate plunger. If plunger is reused,
saturate wick with 40 weight hydraulic oil
before installing in seal retainer.
d) Replace collar in seal retainer.
e) Loosen plunger retainer 4-5 turns. Push plunger
towards crankcase until plunger retainer pops out.
f) Unscrew and remove plunger retainer and gasket and
remove ceramic plunger.
2) Reassembly:
a) Carefully examine each plunger for scoring or cracks
and replace if worn.
NOTE: Ceramic plunger can only be installed
one direction {Front to back}. Do not force
onto rod.
b) Replace stainless steel gasket.
c) Examine gasket O-Ring and back-up ring on plunger
retainer and replace if cut or worn. Lubricate O-Ring
with silicone based O-Ring lubricant for ease of
f) Lubricate outer surface of O-Ring and back-up ring
with silicone based O-Ring lubricant and slowly thread
plug into chamber. Exercise caution to avoid extruding
the back-up ring.
b. Removing discharge manifold:
1) Remove the 8 M16 x 110mm hex socket screws.
2) Tap the back side of the discharge manifold with a soft
mallet and gradually work head from pump.
c. Removing the inlet manifold:
1) Remove the 8 M16 hex nut and M16 split lock
washer.
2) Rotate crankshaft to separate inlet manifold from the
crankcase. Tap the rear of the inlet manifold with a
soft mallet and gradually work from pump.
NOTE: Exercise caution and keep manifold
aligned with plungers to avoid damaging
plungers as manifold is removed.
d. Servicing the packings:
1) Disassembly of High-pressure Seal:
a) Place the crankcase side of the inlet manifold down.
b) With reverse pliers, remove discharge valve spacer
then lift packings and adapter assembly from
chamber.
NOTE: If reverse pliers are not available,
remove the exposed O-Ring and back-up
ring from the discharge valve spacer. Insert
screwdrivers on opposite sides of the O-Ring
groove, partially pry the discharge valve
spacers from the inlet manifold, then work
out by hand.
c) Remove the male adapter, v-packings and female
adapter by hand.
2) Reassembly of High-pressure Seal:
a) Insert the female adapter into the seal chamber.
b) Assemble both v-packings. Lubricate the outer
surface of the packings with graphite based silicone
lube, and insert into the seal chamber with the “v”
side up.
c) Install the male adapter.
d) Examine the O-Ring and back-up ring on the
discharge valve spacer and replace if cut or worn.
e) Lubricate outer surface with graphite based silicone
lube and insert discharge valve spacer into seal
chambers. Spacer with springs should be installed
with springs towards the male adapter.
3) Disassembly of Low-pressure Seal:
a) Place the inlet manifold on blocks with crankcase side
