Another member thought I should start a thread dedicated to the crank swap on my tractor so here it is:
I bought this 1952 John Deere AN last Oct. The PO told me that it had a bad clutch and he wasn't willing or able to fix it. All he wanted was a little money for the almost new looking rear tires. We agreed on $400 for it so I hauled it home. Once home I looked it over and found the crank splines on the clutch side were badly worn so much so that the clutch drive disc was really loose and couldn't be tightened. I purchased a used crank and a new drive disc to swap out with the old. So now on with the project.
I'll start with some picks of the damaged crank and the used replacement.
