With gear off crank, and gear on shaft, is shaft hard to spin? And what did you hit with the hammer? 
It looks like some more backyarder secrets are going to be spilled, the trusty hammer comes into play yet again.

Yes with gear of crank it is hard to spin and I hit the clutch side of the crank with a block of wood and hammer
Like I said I put in the bearings heated the race slid the brand in heated the other race dropped the case on just like in the kor video
Oh I am barking up the wrong tree, really need my new specs.
I read it that you hit the crankshaft with a hammer softened by wood.
Did you install the bearings in the counter shaft, were the free before you installed them.

Hang on, I am not going senile you did say you hit the crank.
Will the balance shaft spin without the gear on?
Why was a hammer used, and what did it do, was the balance shaft gear on when you hit it.
I am either confused or having an out of brain experience.
How would you like to explain the whole problem again to clear things up.
Yea it was fine and I did hit the crank with a hammer and wood after the cases where bolted up to set the crank
yes the crank spins great once i put the drive sproket on its tight after taking off for the 3rd time i realized it it the counter balace shaft and sproket that are tuff to spin i have the main drive sproket off and have to put some omfh into it to spin the counter balace sproket i want to know what i can do to fix this or if it is normal all bearings in the cases are new hopefully someone can tell me whats up and hopefully i wont have to split the cases again
Ok never mind I stopped being stubborn and took the sproket off and realized the u shaped holder for the bearing under it I had it on opposite side so the counter shaft sproket was hitting it
Good catch!!! Now before closing it up double and tripple check everything and make sure it is all tightened and in it's correct place.
Inspect that gear closely, if it fails it ain't pretty. Ask me how I know. It's a three piece unit with two pieces riveted together sandwiching the gear with rubber cushions in it. Also be sure you time it correctly.
