Well, a press is always handy for the removal of cranks, but not everyone has a press lying around just in case. To overcome this failure on my part, I have had success with the following. Place the nut on the end or the crankshaft to keep from battering up the threads, Place the crankcase on a firm surface (I use a flat piece of heavy iron) usually I put a thin piece of hard wood between the iron and the crankcase, and using a rather heavy hammer drive the crankshaft out. Thisd has worked for me, ''CAUTION'' Keep your fingers out of the way. It helps to keep the neighbors from hearing your ability to cuss while the blood blisters grow. Flathead 4
It's important that the crankshaft hangs free when driving it out of the case.
