3) Normally the seal assemblies remain in the
manifold, however part of the assembly may
remain on the plunger. CAREFULLY side
off these pieces.
To remove the seals insert a slide
hammer/extraction collet into the seal.
Tighten and pull up on the slide hammer
weight. The seal assembly should come
completely out.
4) Thoroughly clean the seal cavity.
5) Inspect the seal cavity for signs of damage.
c. Packing Installation:
Tools required: Seal Insertion Tool
1) Ensure that the seal cavities are clean and dry.
Do not use lubricant.
2) Place a seal insertion tool in the seal cavity,
and place one high-pressure seal squarely into
the tool. The high-pressure seal consists of
two pieces, the inner seal and the outer
retainer. These parts are fragile so handle
them with care.
Place the seal push tool on top of the seal and
push the seal assembly into place. Repeat the
process for the remaining cylinders.
3) Install the O-Ring in the outside groove on the
low-pressure seal retainer. Next, install the
low-pressure seal into the retainer with the
closed portion of the seal being placed into the
retainer, and push into place. Install the entire
housing into the seal cavity with the seal
opening in first.
4) Finally, install the seal retainer with the
smooth side against the low-pressure seal
retainer. The manifold is now fitted with new
seals.
d. Plunger Inspection and removal:
Tools required : 3/8” Ratchet Driver; 13mm
Socket; O-Ring Pick.
1) Inspect the plunger for any sign of damage
(Surface scuffing/ scoring, cracks, or pitting).
The surface must be absolutely smooth.
2) Remove the plunger retaining nut and stainless
steel washer (Note: This is the only area in the
pump where a thread locker is used.) The
washer may be stuck to the plunger. Use the
O-Ring pick to clean off the thread locker and
free the washer.
3) To remove the plunger, twist in either
direction and pull straight off. DO NOT USE
any type of pliers or metal tools on the plunger
as they are ceramic and are brittle. Inspect the
plunger again for any sign of damage also look
into the bore of the plunger for any sign of
rust. Rust here indicates that the plunger
retainer O-Rings have failed, allowing water to
leak between the manifold and crankcase and
allowing for water to enter the crankcase
section. Check the Crankcase Section for signs
of water intrusion.
4) Remove the plunger O-Ring and anti-
extrusion ring (Note: The anti-extrusion ring
is cut at an angle) with the O-Ring pick. Once
these are off, remove the slinger using needle
nose pliers.
Note: Discard the slingers, DO NOT reuse
them. They lose their original dimensions after
use.
e. Plunger Installation:
Tools required: 3/8” drive Ratchet; 13mm
socket; Torque Wrench; Medium Strength
Thread Lock
1) Clean the old thread lock off the plunger rods.
Do not use assembly lubricant.
2) Push the new slingers into place at the bottom
of the plunger rods.
3) Carefully slide the new O-Ring into the
groove on the plunger rods
4) Slide the anti-extrusion ring into the groove
behind the O-Rings
