8. Another method is to
use a two-prong slide
hammer puller. Insert
the prongs into the
piston guide allowing
the prongs to grab
under the support
ring then use the slide
hammer to pull the
packing stack up and out
of the head. (See Figure 25)
NOTE: Damage to the piston
guides and or the seals may occur
during removal. Inspect carefully
before reusing any components of
the packing stack.
9. Remove the high-pressure
packing by pulling
straight out with your
finger. (See Figure 26)
Assembly:
1. Install the high-pressure
seal into the head.
NOTE: It should fit snugly. The
packing support is part of the valve
cage.
2. Place the high-
pressure seal at an
angle and work it
into the cylinder. (See
Figure 27)
NOTE: The point of
the “V” or flat side of
the packing is pointed at
you.
3. Lubricate the packing retainer
O-ring with a light
film of oil and install
it into the cylinder.
Push it completely into
place. (See Figure 28)
NOTE: The O-ring
will seat just inside the
manifold and you will hear
a slight pop.
4. Insert the low-pressure seal by
placing it into the
cylinder in at an angle
and pushing it into
place. (See Figure 29)
5. Put a thin coat of
oil on the plungers and
packings. (See
Figure 30)
6. Carefully install
the manifold
and torque
the bolt to
the
proper specifications.
(See Figure 31)
Valve life is dependant
on many variables. Hard
water, cavitation, corrosion,
chemicals and equipment
care. The valves are a
wear item and need periodic
replacement. Worn O-rings or
damaged valves will cause pressure loss
and pulsations.
NOTE: Water seals are wear items.
Life of the seals is dependent on
many factors. Water seals should be
replaced when water leak or a loss of
performance is noticed. Prompt

replacement of worn seals will insure
peak operating performance and
trouble free operation. The water
seals and their respective components
sometimes referred to as the packing
stack, will vary slightly between models.
But the constant between models is
that the packing stack will consist of the
following items:
Piston Guides - which usually house the
low-pressure seal
Low-Pressure Seals
Piston Guide O-rings
High-Pressure Seals
Support Rings

Oil
- AR64545 - Container is 4.5 fluid
ounces. Specially formulated for the
demands of the SJ and XJ series pump.
See parts breakdown.
NOTE: No other oil is factory approved
for this pump. Using any other oil may
result in Drive End Damage.
Winter or Long Time Storage
1. Drain all of the water out of the
pump.
2. Run a 50% solution of a RV or
non-toxic/biodegradable antifreeze
through the pump.
3. Flush the pump with fresh water
before the next use.
4. In freezing conditions failure to
do this may cause internal pump
damage.
5. For long periods of storage in
non-freezing areas the solution
will keep the seals and O-rings
lubricated.
