: PLEASE HELP>>> Bearing too small?

I posted this a few days ago, but got no response. I'm removing my balance shafts. I got this engine used from some guy in michigan who had started the job, but hadn't finished it. I got a brand new inner bearing, and to my suprise, IT DOESN'T FIT! I tried a couple different bearings from my old engine, and they don't fit either! And I KNOW it's the right bearing. I tried the outter bearing (next the the front case), and it ALMOST fits. It goes it nicely, but isn't really tight. if i mess with it enough, I can still pull it out with a screwdriver. It's REALLY close, but not close enough. My question is, can I use something like a high temp sealant on it, wait until it cures, then move on? Or is there anything I can do in the meantime to block that hole with something else? I really don't want to completely disassemble the block, because I'm going to be afraid of crankwalk when i reassemble it.

By the way, there was no bearing in there when I got the engine, so i have nothing to compare the new factory one to. PLEASE help! i'm on a deadline here and could really use your help. Thanks in advance.

You may have them backwards, The innermost bearing is smaller than the outer so that you can install the balance shaft properly, This is how cam bearings are on V-8 engines. They get progressively smaller as you go further into the block.
