    Minimum is .5mm (.0196"). If you check the overall width of the crank web is 52.0mm +/- .1mm (2.047" +/- .004"). There is no maximum given ! I have never had a 390 rod that has side wear. The wear point is always the big end and small end.

    Remember that that on the Husqvarnas in this section the rods are centered within the piston. They are known as piston driven because the big end of the conn rod floats between the crank cheeks.

    Don't forget the rod is centered by the two thrust washers on the wrist pin. The big end floats freely.
