"We have heated our delivery truck straight axles at work bright red and beat the king pins out with a sledge hammer with full over the head swings, sometimes it just takes as much force as you can apply!"

Joe S and Joe H,

Here is what a single cylinder Bultaco crankshaft looks like. As you can see the pin that the 2 crank halves are pressed on to is similar to a vehicle kingpin. The crankshaft that I couldn't press apart was similar to this. After piercing a hole through the pin it pressed out easily. Piercing that hole with a flame cutting torch left the crank halves so cool they could be picked up with bare hands because they are massive and the piercing only took a few seconds. No brutality was required nor would I have used any because these are precision parts.
