Bruce is correct, if all the crank pins are off in the same direction by the same amount, everything is fine.
The math, simplified, (for my benefit) works like this. A K-36 has a 24 inch stroke. Thus, the crank pins run in a 24" diameter circle. A half degree error in one pin= 24 x pi divided by 720, the number of half degrees in a circle, = .105". For the non mathematically challenged, there are other ways to figure it but this works for our purposes.
The rod bushings on the #3 pins are floaters, meaning that they turn freely on both the crank pin and in the rod. The others are solid, meaning that they are pressed into the rod and turn only on the crank pin. When new, we build the bushings with .015 clearance. So, the #3 bushings have a total of .030 clearance, .015 on the pin and .015 on the rod, and the the #2 bushings have .015 for a total of .045 clearance on each side. Between the two sides there is a total of .090 clearance between the #2 and #3 pins and rods. That means, in theory, that you can have one crank pin off by as much as .090" and there will be enough clearance in the bushings to avoid binding. Any more than that and the rods will bind as the wheels turn until something wears and creates the necessary clearance. (I am ignoring the potential clearance between the driving boxes and frame.)
The closer that everything is to being correct, the less wear and tear there will be on all the moving parts.
In 1981 I was working for the D&S. That summer, the 473 was a notoriously hard riding engine that pounded badly, especially when drifting. However, after it was run for a couple of months, it smoothed out considerably. The shop noted that it was wearing one of the rod bushings out and replaced it. The hard riding and pounding returned. I was told that when they took it apart the following winter they discovered that one of the crank pins was off by about 1/4". This made the rods bind causing the hard riding and pounding. Things improved once the bushings wore enough to make enough clearance to compensate for the out of quarter crank pin.
