You do not bob weight balance a crank for an inline 6 engine, you balance the crank by itself and you balance the rods by themselves.(01-27-2019, 05:54 PM)baldurYou are not balancing the up and down motion with the crank. Your are balancing the rotating mass of the crankshaft. The pistons are balanced by their weight as well as the rods big end and small end. It doesn't matter if it is an inline or opposed cylinder. Balancing is balancing.(01-27-2019, 03:14 PM)Turbo you said -"You don't rebalance an inline 6 crankshaft for the weight of the pistons."
why not
are these guys below wrong?

Inline 6 or inline 4 cranks have pistons moving up and down on one axis only. You cannot balance up and down motion by anything you do with the crankshaft. This isn't like a V8 engine where you have two axis of piston motion that are perpendicular, so these guys are right, but if you apply the same technique to an inline engine you are wrong.
