CAUTION
Refer to CMM Parker Cleveland P/N AWBCMM0001-7
last issue for more details about wheel assembly
inspection/maintenance instructions
1.
Make sure the inside of the tyre is clean and
dry. Inflate the inner tube just enough to
round it out. Install the tyre and inner tube
on the outer wheel half, inserting the valve
stem through the valve hole in the wheel.
Place the inner wheel half inside the tyre.
Align the marks made at disassembly with
those on the outer wheel half.
Refer to Figure 12.
2.
Install disc in inner wheel half and align
bolt holes with wheel half.
Refer to Figure 12.
3.
Install bolts (7) through brake disc and
wheel halves (take into account the
recorded halves relationship). 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.
4.
If removed, carefully fit bearing cup (4) –
see CMM for detailed instructions. Fit
bearing cone (4), seals (2,3) and snap ring
(1) into each wheel half.
Refer to Figure 12.
5.
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.
