You need to take it back to the shop and have them look it and figure out what the problem is .
Oh and have your crank cut .010/.010 so you don't have to HACK your bearings ...

i was just about ready to do that and after the 4th time working these bearings i figured what the heck, just lay the crank to get it off the floor and see if by chance it would fit and WHAT? it spins like a dream. it's unbelievable how much material needed to be removed but it worked. would having the crank cut remove the radius or how would that help this issue? i'm learning here as far as aftermarket cranks and internals. thanks

i'd love to see a couple pictures of those bearings now, if you don't mind.

i should have taken pics but the rear seal is in and after taking the caps off 6 times they are staying put. but i'll tell you that i used a random orbit sander to bring the total width of the bearing down to 0.936 then put a bevel of between 1/32 and 1/16 by the time it was all said and done. it is a 440source crank and i am happy with it, it is straight and i mic'ed the journals and they are perfect. laugh at me if you want but i 'm just happy all my frustration and work finally paid off

My 440 Source 4.15 RB crank impressed my machinist with it's tolerances. I've heard of a few guys having a few problems, but they're a good crank for the money. On the other hand, a friend of mine bought a complete Hemi stroker from INDY at the Mopar Nationals a few years back and has had a LOT of problems with it. After less than 4,000 street miles, he's in the process of completely rebuilding it and correcting several problems. The key is in knowing what your clearances are and paying attention to details in order to remove as many potential problem-causing variables as possible. Your work will pay off. I think your build will turn out just fine.

I had a small block 360 do this to me once. It had studs, and the caps were opened up to clear the studs, yadda yadda, all the fun stuff was done. I still had a tight feeling. Like Dan said, if ya have to hold pressure on the screw driver to get end play something is wrong. An older guy, in his 70s, told me to take a dead blow hammer, a large one, and smack the snout, and the flange front to back a few times. He said some thrust bearings dont get shaped very well, and need to be matched up to your thrusd surface. I did that, and It freed up my assembly. Sounds like ya champfered the bearings, and have done youre homework. Dont know if this has been stated yet, but I hope you get the combo feeling correct cause it sucks doing it 2 times.
Good luck, and the Jabs seem to come from everyone sometimes, but atleast you are getting it going.

i hope your not as thin skinned as some here. those weren't jabs. i was simply asking a question.
it's unusual for the chinese cranks to come in exactly on the low number, but if you say so, i'll believe you. i was curious as to what your final bearing clearance ended up being too. it's odd how you had a machinist do the trial fit and then nothing fit. it's also odd that you had to do all that work sanding and cutting on the bearings to get the crank to rotate. hopefully the rest of the build goes a lot better and easier.
i was serious when i said i'm glad your happy, you went to a lot of trouble to get everything to work right, you should be happy.

I agree 100% with JohnRR. I have an Eagle crank in my engine that was turned .020/.020 and it also had the radius corrected and when I laid it into the block it turned like a dream with no trimming required
Gus 
Exactly , the CCJ cranks are WRONG. For some odd reason people believed the pied piper when he said to HACK your bearings to fit an incorrectly SANDED to finsh crank journal. My Eagle blem was cut to fit a low deck and offset ground, the radius is correct and it uses bearings shells OUT OF THE BOX, no HACKING required mains or rods and it doesn't even need the bandaid narrow rod bearings.

FWIW, I have a 440Source 4.250" crank for my back up motor (budget). They must have at least one guy doing acceptable grinding. My mains measured:
2.7495
2.7495
2.7494
2.7495
2.7493
And the bearing clearances were all between 0.0027-0.0031".

Jim, did you have to clearance your bearings?
Some will definitely be better than others, the first one after a sandpaper change would be alot better than the last .
