Operating Instructions and Parts Manual RC Series Pumps
DISASSEMBLY
1. First remove the eight 5mm head
bolts.
2. Place the screwdrivers as shown
between the head and crankcase of
the pump, lifting
one up and the
other down. The
head should start
to lift off of the
plungers. (See
Figure 17)
3. When you remove the head you
may notice that some of the
water seals have stayed on the
plungers and some in
the head. To remove
the seals from the
plungers simple turn the
assemblies and pull off.
(See Figure 18)
4. If the seal assemblies are in the
head use the reversible pliers to
grab the seal retainer on
the outside ring, twist
the retainer in either
direction (this is done to
free the retainer O-ring
which is stuck to the
manifold) and lift out.
(See Figure 19)
5. With your fi nger pull
out the brass intermediate guide
ring.
6. With your fi nger pull
the high-pressure seal
and head ring out of
the head. (See Figure
20)
7. The low-pressure seal is located in
the brass seal retainer. Using the
mechanics pick, go in
between the seal and
retainer and pull the
seal straight out. (See
Figure 21)
8. Remove the seal
retainer O-ring with the
mechanics pick. (See Figure 22)
ASSEMBLY
1. Install the plastic head ring
into the head (the fl at side
is on the bottom).
2. Install the high-pressure seal. Place
the seal so the open “V” portion is
toward the head ring. You need to
place the seal at an
angle and pull and
push to work the seal
into position with
your fi ngers (do not
use any tools you may
damage the seal).
Make sure the seal is
totally seated against
the head ring. (See Figure 23)
3. Place the brass intermediate ring
squarely over the high-pressure seal
4. Install the low-pressure seals into the
rear piston guide. Make sure the
brown scrapper ring is in place on the
backside of the seal (NOTE: Care must
be taken so the ring does not fall out
during assembly). The
scrapper side of the seal
goes into the piston
guide. Push the seal
down until fully seated.
You should be looking
at the open side of the
seal. (See Figure 24)
