Alright, i need a little help. I'm trying to tear down my KTM to put a new top end in it, and i've ran into a stumbling point. I got everything torn off and the head off, to find a huge chunk of something on top of the piston. However, that's not my problem. The problem is i can't get the engine out of the frame. There is one bolt (or something) that runs through the frame, through the swingarm, through the engine, through the other side of the swingarm, then back through the other side of the frame.
Here is what it looks like on one side:


and on the other side:

on this side, the end is threaded (u can't see that), so i'm guessing there is supposed to be a huge nut on it too.

How am i going to get that rod/bolt/whatever it is out of there, so i can take the engine out??!???!?!?!?
