Exhaust Manifold Stud Size?

[sitdwnandhngon]

New member, bought a 1970's B7100 a few weeks ago and I am slowly making into a solid tractor again.

I removed the exhaust manifold today only to find one of the studs was broken. Are they a standard size that I can find at my parts place, or will I have to special order one from Kubota?

Should be a standard metric size, likely same as some import cars. I would take one of the good ones out, and take it with me to the local parts place. Or take a thread gauge, and find the thread pitch of both ends and the length, and try the internet...

I just bought nuts and washers for my B6100's muffler and the manifold studs/nuts appear to be the same size: M8x1.25. Best to take a nut with you to verify.

The parts guy had a whole box full of metric studs.

Good to know they are easily found.
