JD 4255 Bolts for duals

[Sandfarmer]

Half of the bolts snapped and I'm having trouble finding replacements online. The couple that I have on hand are 5/8 x 3 inches with flat cap on end and tapered collar.

What the heck made them break? Look like they been broke for a while.

Not sure what made them snap; I probably failed to make sure all nuts stayed tight. Yes, they broke last Fall during harvest and I'm just now getting serious about putting duals back on. Don't use this tractor except grain cart and Bushhog.

I suspect you know those U clamp dual hubs are not made by John Deere, Deere uses a split wedge mounting style. Is there a manufacturer name cast into the hub? I would think any tire shop that deals with trucks would have a stud supplier book that would list replacement studs by size so they could order them for you.

Thank you. I will check with my local semi mechanic and my tire guy.

Have you checked with your JD dealer? The hub most likely is not a JD product but something such as Unverferth sold through JD dealers. Make sure the bolt spline size and count match so as not to damage the hub.
