Reassembly
Step 6. (Reassembly) The inside of
the valve body must be wiped clean
and free from scratches or burrs prior
to reassembly. Lubricate the new
valve O-Ring and U-Cup. Place the
U-Cup seal inside the valve body. The
"U" of the seal must be facing down
against the valve body shoulder. Care
must be taken to insure that the seal
lips are not chaffed by the threads on
the body upon insertion. Install the
O-Ring onto the valve body. Place
new spring on top of the valve.
Step 7. Lubricate and replace the
O-Ring on the center post assembly,
adapter end, with the new O-Ring
provided in the kit. Insert center post
adapter into the valve body and
wrench tight. Do not use a collapsible
wrench on the center shaft.

Step 5. Remove the purge valve and
springs from the valve body located
in the lower portion of the housing.
Inserting a screwdriver into the purge
hole at the bottom center of the
housing and pushing upward will help
free the valve so that it can be
grasped.
Also, remove the U-Cup
seal from the valve body.
Caution: The valve body housing is
aluminum. Care must be taken not to
cross thread the post assembly into the
valve body. Do not bend the center
shaft by applying excessive side load.
Step 8. Lubricate and replace the
canister O-Ring and install the canister
into the housing. Also replace the
O-Rings on the purge plate assembly
and stack it and the desiccant spring
on top of the canister. Replace the seal
washers on the center shaft (both
ends) and thread into post assembly
wrench tight.
Step 9. Replace the outer housing
O-Ring and reassemble the cap to the
housing. Retighten hose fitting at outlet
port and check system for proper
