Wouldn't you need to place them 180 degrees apart and facing the same direction with respect to the orientation marks to get identical balancing? ....or perhaps placing them face to face is the same thing.....I am not sure.

Dohhh!!!

Thanks for the correction.

After thinking a bit more, if the old and new are back-to-back or face-to-face, then the new FW will be 180 degrees out of balance.

They should be facing the same direction, BUT the orientation marks still need to be at the same clock position.

Another key point is to make sure the bolt holes line up identically, so that you actually can bolt up the new FW so that the orientation marks on the crank to the FW match.

I cannot see how keeping them in the same position with respect to the clocking marks will result in an identical balancing, unless there is something in the method which corrects for it.

So I was right the first time? Sheesh...

OK, thanks again for the correction.

(3) should read "Mark the new FW at the 9:00 position (i.e. 180 degrees opposite to the old FW).

There still is the issue of lining up the bolt holes to ensure the new FW can be mounted correctly...
