(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(01-27-2019, 07:49 AM)baldur Full of fail. You don't rebalance an inline 6 crankshaft for the weight of the pistons. It's simply not possible.you said -"You don't rebalance an inline 6 crankshaft for the weight of the pistons."
But as for journal grinding, yes you can grind journals on a crank that has not had a bearing spun on it. Crankshafts that have had a bearing overheat lose their heat treat.
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.
