Seal-wash assembly seals:
4. Wet the seal insertion tool, each new seal, and seal opening with 100%
alcohol.
5. Place the new plunger wash seal on the seal insertion tool with the
spring side facing away from the seal insertion tool, and insert the tip of
the tool into the seal opening, pushing firmly to install the seal. Repeat
this procedure for each of the tube seals.
6. Reinstall the seal-wash housing assembly washer (see the figure
“Plunger, seal-wash, and head:” on page 193).
7. Slide the seal-wash housing and washer onto the plunger, and then
insert the assembly onto the head (see the figure “Plunger, seal-wash,
and head:” on page 193).
8. Follow the instructions in the Head Removal and Replacement screen to
reinsert the head, seal-wash assembly, and plunger. To avoid damaging
the tube seals, and to properly align the seal-wash tubes with the
seal-wash housing, refer to step a through step d below. Also, make sure
that the head alignment pin is properly oriented and that the “J” tube is
facing downward (see the figure “Plunger, seal-wash, and head:” on
page 193).
a. After finger tightening the head nut onto the head, loosen the nut
approximately 1/2 turn.
b. Inspect the ends of the seal-wash tubes for damage. If necessary,
trim the ends with a razor blade.
