instructions, maintenance instructions, and illustrated
parts breakdown for the remote inflator assembly and
dual chucks stem gauge.
The tire inflator assembly kit consists of a remote
controller, a low- and high-pressure gauging element,
and a 10-foot service hose. The remote inflator
assembly should be calibrated upon initial receipt,
before being placed in service, and every 6 months
thereafter. The unit is equipped with a built-in relief
valve to prevent overpressurization of a tire during
inflation. The relief valve should to be set at 20 psi
above the maximum pressure required. It should also
be sealed with a calibration void if seal broken
decal. The needs of each activity will be different,
depending on the type of aircraft supported. For
example, an organizational activity with a single type
of aircraft will only need a single inflator assembly.
An activity with multiple types of aircraft will need an
inflator assembly preset for each type of aircraft,
based on the required pressure. Intermediate
activities (tire shops) should use two gauge elements.
One element for use on tires in the range of 10 to 150
psi. Another for a second inflator with relief pressure
set at 500 psi for tires ranging from 136 to 480 psi.
The inflator assembly controller relief pressure
should be clearly labeled or marked. The carrying
case should be labeled with the type of aircraft for
which the relief valve is set. Figure 11-23 shows the

After the buildup of a new tire at an AIMD or
IMA, it should be placed in a safety cage for inflation.
A typical safety cage is shown in figure 11-24. The
method of inflation used depends on whether a tube or
tubeless tire is being inflated.
To inflate tube tires, you should remove the valve
core and place the wheel assembly in the safety cage.
Attach a remote tire inflation gauge assembly to the
valve stem. Be sure the inner tube is not being
pinched between the tire bead and the wheel flange.
On remountable flange wheels, be sure the
remountable flange and locking ring are seated
properly. Secure the safety cage door and inflate the
tire to its maximum operating pressure. This will seat
the tire beads against the rim flanges. Deflate the tire
