Bad news from the machine shop
I took my motor into the machine shop a few days ago and I got a call today saying the crank in my K241 had been ground before and now the main journal is .012" under nominal, so he can't re-grind it for a .010 rod. This was his first step, so I'm not out anything yet money-wise, but I'm not 100% sure what to do from here. So far, the rest of the block looks good enough to save with either a .010-over bore with an absolute max of .020-over being needed.
Looking for options from those who have gone down this road, or had machine work done, before.
He did give me a few options though; 1) grind the crank to .020 under & use an aftermarket rod sized for this - if a rod exists. A friend of his mentioned this idea to him, 2) spray-weld my crank, then grind it for .010 under and use the new .010-under rod I currently have, 3) find another good crank that has enough meat on it that it can be ground appropiately for a .010 rod.
I plan on using this tractor as it was originally intended, so it will see its use and see some long hours doing all kinds of chores. I did find an aftermarket .020-under rod on Ebay though I'm not terribly confident in its quality in regards to craftsmanship & longevity.
