11-A. Seal the LP seat
hole with thumb.
11-B. Place the balance
chamber onto the stem
just enough to cover the
o-rings.
Refresh these
components with new o-
rings.
Following are some
suggestions – to facilitate
assembly.
12. Now squeeze the
components together –
creating an air spring.
Note: The chamber
should “spring” up and
down, as you push and
release.
Tech tip: “micro-adj.”
Temporarily screw the
“micro-adjust” (adj.
screw) into the
”adjustment-shaft”. This
will give you more control
to install the 126 o-ring.
Note: If the components
go flat, submerge U/W to
detect leak - revealed by
bubbles.
Tech tip continued…
14. Push and spread the
126 o-ring onto the end
with the “nipple”.
13. Pre assemble the
poppet, spring and
balance chamber. Orient
the pair of “poppet
shoulders” (down) in
relation to the lever (up)
and insert into the case
inlet tube.
Once the 126 o-ring is in
place, unscrew the
“micro-adjust” and
proceed.

The objective is to engage
the poppet assembly with
the lever-tabs. Apply
pressure with your index
finger and the lever
should rise.
15. Following is dynamic
application , lubricate the
o-ring groove and slide
the 293 o-ring down the
“adjustment shaft, into
the first/true o-ring
groove. Then lubricate
the male threads.
Continued…
Maintain the “spring-load”
and push the lever down.
If correct the lever will
return (under spring
load). Cycle several
times.
16. Spread the 351 o-ring
onto the metal sleeve.
