This looks to be like a quite tight definition of "properly". If the holes aren't bored a lot closer to square than many teams can probably manage, the belts on the drive shaft will migrate one way or the other, and shall end up rubbing on the bearings (not TOO bad, but not optimal), or each other (as described), or both (one goes to a bearing, the other is jammed against the first belt, with the same results). The 'both' case actually seems rather likely as I work through the variations.
