Just to explain, in basic terms, a couple of things;
a/ all B747's, other than the -400 series, are known as CLASSICs,
ie, the SP, -100, -200 & -300 series.
b/ the amount of turn deflection of the body gear, in relation to the nose gear, is such that the wing gear struts/ bogies are not normally subject to much more than twisting forces, at taxiing speeds, and those forces are always kept in mind when rather sharp turns are required, at v/slow speeds, ie, always keep the aircraft moving forwards, to relieve the stresses.
Basic Captain stuff!!
