this step

Remove the two-piece cover, friction
washers and diaphragm from the
second stage housing.

Remove the washer from the air inlet.

Using the universal tool remove the
housing plug by turning and then
pushing from the inside of the housing.

Use a 13mm or ½” low torque (thin)
wrench to loosen and remove the valve
body. The wrench should rest on the
“flat” sides of the valve body, which are
designed to permit gripping by a
wrench.

Caution: Do not score the threads on
the valve body when applying the
wrench. Scoring the threads will result
in damage and require replacement of
the valve body.
