I scored this engine second hand and would like to replace the crankshaft bearings before I run it but cant figure out how the crank comes out.
I've removed circlip, wristpin, piston and liner and logic told me if I take the big end to BDC and pulled it out and rotated thread end up toward the top of the engine the crank would rotate out of the case but it won't come .
Is there something I am missing here. I don't want to force anything in case I damage the crank or case.
Hopefully some of you CMB engine wizards can explain where I am going wrong.
