Hello  Have 30-30 312 crankshaft for sale. It was from local machine shop that has been business since 1950s. It was ground and put in inventory in the 80s. Pretty dirty but in a box no surface rust. Measured out dead on, thrust bearing has  about .004 end play with new bearing insert.  Key ways look good.Thinking $400 plus shipping. But I have no idea if this is too much. Box is 9x9x32 inch long. #60 pounds from 97424 Oregon. I don't know how to do pictures. Bill  bcosler@msn.com

Hello  I have had no interest in crank. I assume it is priced to high. I will try at $300 plus shipping. Bill  Oregon

Bill.  My casual following of 312 cranks on eBay indicates that a $300 'Buy-It-Now' price should provide a sale although you may have to list it more than once to reach a buyer.

IF you have not had the crank magnetically inspected, I would recommend having it done with a machine shop receipt to show for it.  My recollection is that the cost on having the mag test is less than $50.

In working with the machine shop, I would steer them to pay particular attention to the crank snout connection at the first main bearing surface and the radius-es related to the first crank throw.  Yes, the entire crank should be checked, but my understanding is that these particular area are more prone to problems . . .

Some may hesitate at the crank having been turned .030 under-size at both the mains and rod journals.  Retaining the quality of the main bearing and rod journal radius-es is important for y-block crankshaft integrity.

Hope this helps!
