 (d)  
While you turn the wheel again, tighten the nut to 110 pound-feet.

 (e)  
If the holes in the axle for the lockbolt are not aligned with the slots in the nut, do these steps: 1) Tighten the nut more, if necessary, to align the lockbolt

 holes. Do not tighten the nut to more than 160 pound-feet.
 2)  Do not loosen the nut to align the lockbolt holes. If the lockbolt holes are not aligned at the maximum permitted torque, fully loosen the nut and do steps (a) thru (d) again.

 NOSE GEAR WHEEL AND TIRE - REMOVAL/INSTALLATION
_______________________________________________
 1.  General_______
 A.  This procedure contains two tasks. The first task is a removal of the wheel and tire assembly for the nose gear. The second task is an installation of the wheel and tire asembly for the nose gear.
 B.  When you replace a nose wheel and tire assembly, you can replace the wheel and tire assembly on the other side. Differences in the diameter between new and worn tires can contribute to nose landing gear vibration. You can decrease this if you install tires that have equal pressures, nearly the same inflated diameters, and matching supplier part numbers.
