Procedure
Additional info &
References
Make sure the inside of the tyre is clean and
dry. Inflate the inner tube just enough to round
it out. Dust inside of tyre with the correct talc.
Insert inner tube into tyre with the "arrow" on
the tube next to the red dot on the tyre. Put the
tyre and tube on the outside wheel half with
the valve stem through the valve hole. Put
inner half wheel into tyre. Align the marks
made at wheel disassembly with those on the
outer wheel half.
Install disc in inner wheel half and align bolt
holes with wheel half.
Install bolts (7) through brake disc and wheel
halves. Inspect bolts and washers (6) prior to
assembly (bolt heads are to be on brake disc
side of wheel). Torque nuts to value specified
on wheel nameplate.
Refer to Figure 12.
Observe the torque required to
turn the nut (free running
torque). This value must be
added to the value stated on the
casting/nameplate to obtain a
true torque value.
Inflate tyre to correct rated inflation pressure.
Deflate tyre to let tube adjust to proper
position. Reinflate to correct pressure and
install valve stem locking nut. Tyre will have
to have pressure adjusted in 12 to 24 hours.
Check carefully for leaks. When tire is
correctly inflated and leak-free it can be
installed on aircraft.
