Had an inquiry on how the linkage is to be adjusted....so here is a little more of the article:
Adjusting the G-742 Sprag-Type Linkage
If your sprag unit does not behave this way, more than
likely the linkage needs adjusting. This will require you and
a helper (two helpers are actually better, one to shift, one to turn tires, and you to turn wrenches). Still with the engine off, put the transmission in first gear and turn the front wheel one half turn in the forward direction. Have your helper shift the transmission into neutral while you are underneath watching the transfer-reverse-shift-rod lever (see Figure 8). If this lever moved during the shift, the transfer-reverse-shift-rod should be shortened by loosening the jam nut and turning the rod. If the lever didn't move, it may already be correct (bad deal, because then you need to go into the transfer). More than likely, though, the transfer-reverse-shift-rod needs to be lengthened by turning out. Do this until the lever on the transfer does not move during the first-neutral shift, but almost does.
Recheck this adjustment with the transmission in neutral
by trying to pry the reverse shift rod away from the transfer
case with a prybar. If you can not move it, the forward adjustment is correct. If it moves, however, then the rod assembly needs to be shortened.
Now, shift the transmission into reverse and turn the
jacked up wheel a half turn backwards. Make sure the transmission did not jump out of gear (as it is prone to do if this linkage is improperly adjusted). Now try to pry the shift rod lever toward the transfer. One sixteenth of an inch or less of movement is normal. If the movement exceeds that, then the shift rod assembly should be lengthened. Finally, repeat the initial test, if it now passes you are good to go, if it still fails, look at doing transfer case work.
