Reman crank

[caniborrow50cnts]

Brief background: 97 gsx has an ongoing tap, has had a near complete rebuild.
I've come to replace an aftermarket crank that kept botching the rod and bearing in the #1 cylinder. I believe it is Chinese made and probably doesn't meet oem standards. The crank I received now is oem remanufactured. I received matching undersized bearings to fit it perfectly. Main bearings are .5 and rod bearings are .25. I installed 1 & 4 pistons and confirmed the crank worked as designed. I installed 2 & 3 and then turned it again. Nothing moved. Even though they are torqued to spec, the #2 would not spin. Found the #2 on the crank is not undersized (meaning the .25 undersized rod bearings were not allowing movement.) I took new standard size bearings I had and installed them only on the #2 rod and it fixed the issue. I understand that this means that the crank is also off balance by a gram or 2, but my concern is if this will throw off the compression or possibly damage the engine if I decide to install it as is. I know there are some "what if" scenarios out there, but I'm asking because I want to know if any of you have done this or had issues like this before. Thanks.

Wow, I think I would be returning the crank to wherever you got it from... Might work now turning it by hand, but God knows what would happen if you tried to put higher RPMs to it. Probably would be so out of balance that it would damage something or throw a rod... Where did you get the crank from?

Turns out I was close but not right. I got the crank from autozone who got it from crankshaft rebuilders Inc. I had the crank measured but that turned out fine. One of the 8 rod bearings turned out to be .5 instead of .25. I wouldn't have known by looking at them. I confirmed previously that all were stamped showing .25. Guess one went into the wrong machine and got stamped wrong. I'm going to stop by a local shop and get another set to make sure they all match.
