[Farmall] 39 Farmall A crankshaft question

[E. John Puckett]

Al, I am not a professional, but my choice would be take it to a machine 
shop to be measured since you apparently have one you trust.  Normally 
they are also your best source for the rod and main bearings.,
A good source for a crank, though i am not sure they sell ones already 
ground would be www.jptractor.com.  They probably will not have them on 
line, but call them and tell them who you are and what you are doing,  
they will help if they can, and are dependable.  Do you have the 
necessary puller for removing the crank pulley?  It requires a puller 
with a backing plate similar to a bearing separator, if you pull on the 
flanges it will break.  Not might break, WILL break.  Also, the machine 
shop will have a puller and be able to remove it and press it back on.

I know there's no way to tell for sure until they plastigauge it and mic the journals, but I am anticipating best case scenario a crankshaft grind and worst case, weld/grind the crank back down or find another crank already turned, or have it turned.
