Clutch Starter Bearing Issues

[nike_soccer]

I had to buy a new clutch starter cover after I layed down my bike. I ordered only the shell and then had to take out the bearing ring from the old one out. I got it out successfully but when I put it in the new shell I didn't have a press to pressure it in machine perfect again.

Now my starting motor has issues working. Any pointers on how to make the boom arm flow better?
