Re: MS441 Magnum Part Help

I was told by my stihl mech. that you must use crank cases as a pair. if you try to just replace one half, you risk the chance that the bore may be out of alignment by a fraction of an inch, you wouldn't notice it right away, but with the bore being out of alignment, your sure to wipe out the bearings and seals.
but than again you could get lucky and everything aligns as they should (That's never my luck) don't know if its possible or not, but i know when i was building small block chevy engines, my machine shop would align the bore on the main bearings, don't know if that's possible with chainsaws or not?
