blind

Does anybody have any tricks/ideas to getting the blind bearings out of the case halves for replacment, i have 3 different slide hammer sets but none can get behind the bearings to pull, i have 3 bearings that i cannot get to budge, i took the cases into my local bike shop who broke one of there...

was using a pencil to find TDC and then on the third try, the pencil broke off and left a chunk down in my cylinder. Now I have to pay a real motorcycle mechanic all sorts of money to remove my head and get that pencil fragment out of my bike. DAMN! how the hell is a poor weekend warrior...
