3-4. REASSEMBLY.
NOTE: A diagram for the reassembly of the ON/OFF valve and has been laser engraved directly onto the
A.I.R. valve body. This can be followed easily by matching the parts to the diagram and assembling those
parts in the order indicated.
(7) Reassembling the Grip
Using the phillips screwdriver, replace the grip panels.
(6) Reassembling the Sear
Please refer to the accompanying diagram for instructions on how to reassemble the sear.
(5) Reassembling the Powertube
Place the power tube o-ring into the power tube and push it as far down as possible.
Drop the powertube spacer or powertube spring on top of the o-ring.
Re-attach the powertube tip (brass piece) using a coin to screw it firmly into place. The powertube tip must
be secure, but not over-tightened.
(4) Reassembling the Regulator
Place the regulator piston, brass bottom IN, into the regulator chamber. Push it into place using the allen
wrench.
Place the spring pack, wide diameter IN, into the regulator chamber.
Screw the velocity adjusting nut back into place.
Place the regulator pin and spring assembly back into the face of the valve. Note: This is pushed into place
SPRING FIRST. The regulator pin fits inside of the small end of the cone-shaped spring.
Place the regulator seat into the round receptacle located on the face of the regulator. NOTE: this seat has
two different sides, one slightly larger than the other. The larger side should be placed against the
regulator, and should 'snap' snuggly into place when assembled correctly.
Screw the two halves of the A.I.R. valve together hand tight, until the 68MICROMAG logo which is laser
engraved on the body is lined up.
(3) Reassembling the ON/OFF assembly
Nest the small teflon o-ring inside the larger urethane o-ring.
Place the brass on/off bottom piece onto the on/off pin.
Push the end of the pin protruding from the brass piece down onto the o-rings so that you create one
assembly.
(2) Replacing the ON/OFF assembly
Push this entire assembly, o-ring end down, into the on/off hole in the A.I.R. valve.
(1) Replacing the A.I.R. Valve
Place the bolt spring over the bolt.
Make sure that the powertube bumper (large, thin o-ring) is in place over the powertube.
Drop the bolt onto the powertube.
