In a nutshell, the aluminum casting to mount the mast to the
rotor is probably the weak link in the 1000SDX.

FWIW, later production G-1000s include a sheet in the instruction manual telling how to sequence the tightening of the various bolts to avoid putting a bending stress on the cast aluminum clamps, which is what kills them. In a nutshell, you need to be sure the clamps are tight on the mast, then make sure they are concentric with the top of the rotator before you tighten the bolts that tie them to the rotator, and finally tighten the rotator mounting bolts on the rotator shelf.

A big plus for the Yaesus, in my opinion, is that there's no need for shims regardless of the diameter of the mast (within the range of the clamps, of course).
