Rex ® Regulator Re-Assembly - Kirby Morgan 77 Operation And Maintenance Manual

7.10 REX Regulator Re-Assembly
®
1) Note: If you are replacing the inlet valve seat, this
must be done at least 12 hours before installing it
in the regulator. Place a very thin film of silicone
sealant on one side of the inlet soft seat then install
it sealant side down onto the inlet valve and press
firmly and evenly to fully seat. The sealant must be
allowed to dry completely (at least 12 hours) before
re-installing and adjusting.
2) Install the o-ring onto the inlet valve, then lightly
lubricate.
3) Install the exhaust valve onto the regulator body.
Ensure that the valve is not wrinkled and lays flat
against the seat area. Make certain this valve is not
installed upside down. Check proper positioning and
seating by blowing clean air up through the valve. Be
certain the valve does not stick open after doing so.
4) Insert the sleeve into the left side of the exhaust
whisker body. Make certain the groove in the sleeve
aligns with the mating rubber area of the whisker
main body to allow proper sealing. When properly
installed, the end of the sleeve will be just inboard of
the main body end.
5) Hold the exhaust whisker body so the two valve
ports are facing down and the large opening on the
back side is facing you. Install the regulator body into
the main exhaust body with the round inlet tube hole
Note the engraved letter "B" on the main tube. It must face outwards, away from the helmet to be installed
properly.
