2.
Refer to
Figure R-6
during the
following procedure. Place the
piston assembly on a flat, stable
surface with the shaft pointing
up. Slide the installation tool
(provided in the
RSK ) over the
piston shaft with the wide end
down. Lubricate the new PIP
ring, cup seal and the
installation tool with silicone
grease. With the grooved side
facing up, slide the PIP ring
down the installation tool and
onto the piston. Repeat this
process for the cup seal. Note that the grooved side
of the cup seal should be facing down; i.e., the
grooved sides of the PIP ring and the cup seal
should be facing each other. When finished with
the installation, remove the installation tool from the
piston shaft.
3.
Lightly lubricate the cylinder in the pump body with
silicone grease. Slide the finished piston assembly,
shaft first, into the pump body from the side of the
pump body that faces the check valve plate. Install
the large o-ring (8012588) into its groove in the
pump back plate and lower the pump back plate
over the piston shaft. The side of the back plate
with the large o-ring should be facing the pump
body. See
Figure R-7
.
4. Refer to Figure R-4 . Slide one of the white backup washers over the piston shaft and press it
into its bore in the pump back plate. Next, slide one of the two black rubber piston shaft seals
over the piston shaft and work it into the bore on top of the backup washer. Note that the
shaft seals are flared out on one side. It is important that the flared (wider) side should be
down, facing the shaft bore. Install the second piston shaft seal in exactly the same way. It too
should be installed with its flared side facing down. Next, install the second white backup
washer and, finally, the white bushing. Slide the installation tool (used in Step 2 above) over
the piston shaft with the narrow end facing the white bushing. Use the installation tool to
press the shaft washers, seals and bushing all the way into the bore. When finished, the
outside end of the bushing should be flush with the bore opening.
5. Install a new wiper block seal into the wiper block. The seal must be pressed into a groove
inside the bore in the middle of the wiper block with the narrower side of the seal facing
outwards. Form the seal into an oval shape by squeezing it between your fingers and press
one side of the seal into the groove in the wiper block. Once an edge of the seal is started
into the groove, carefully work the rest of the seal into place. After the seal has been
installed, slide the spacer (if present) and wiper block onto the piston shaft. The side of the
wiper block from which the seal was installed should be facing outward. Refer to
Figure R-3 .
6. Prepare the check valve plate for reassembly by installing the new poppet valves. Note that
both the intake and reject poppet valves and valve springs are identical. Refer to Figure R-5
during the following procedure:
