I am in need of a .030 undersize front main crankshaft bearing ( end with the timing gear)
Anything anyone is willing to part with out there, I'm open to other options if anyone has suggestions.

Do you have the part number handy? I have a new one from CAT, but I believe it is for the rear, which I assume not the same? Parts book not here, I can look next week. JM

I had a machine shop measure and the crankshaft is worn to badly for a .030 undersize bearing, am now in search of a serviceable crankshaft.
Thanks

Would anyone have the standard crankshaft specs for the crankshaft in the photo? It's out a D4-6U

well the bearing bores are listed as 1.8200 inches so the crank would be a slight clearance on that

you may be able to speedi-sleave the crank back to a usable size it is also possible to get it built up and reground any good engine reco shop should be able to do that
