1.3 Reassembly
1.3.1
Place inner wheel half (8-35) with brake disc (8-65) and bolts (8-5 or
8-5A) installed on a flat surface, with register portion of the wheel
half up. Place new O-ring (8-20) on register portion of wheel half.
Place tire over inner wheel half, and then place outer wheel half in tire,
making sure to properly align male and female registers. Install nuts
(8-15 or 8-15A) and washers (8-10 or 8-10A). Torque nuts to limits
listed on decal affixed to outer wheel half. When all nuts have been
torqued, torque a second time to make sure that the required value has
been achieved; sometimes O-ring compression will give false initial
readings. Inflate tire to desired pressure.
1.3.2
To complete wheel re-assembly, reverse steps 1.1.2 through 1.1.7
and torque wheel nuts (8-15 or 8-15A) per limits listed on decal
