Ideas for straightening a stud?

[peejay75]

This is a master cylinder mounting bracket for a Jeep CJ. As you can see, the bottom stud is bent. My thoughts are, clean the threads, and try to see where it's bent. Then put on a nut just a bit shorter than the threads, heat it with a MAPP torch and see if I can straighten it?

(I don't own a welder, but...)

If one were to attempt to remove the stud and replace it with a new one, what would that process look like?

Thanks in advance!

That's not a lot of bend. I would use a piece of aluminum, brass or wood to hold the stud up with the back of the bracket off the surface, and tap the edge of the bracket with a hammer until the bent stud aligns with the straight one. Turn the assembly 90 degrees and repeat.

What Fixr said. It looks to be that you may have a bent bracket. I'd lay that on a flat surface and confirm that the ears on the bracket are in the same plane with each other with a square. If they are not then hammer as Fixr said or grab the bracket in a vise and bend the ears with a large crescent wrench. Also confirm that the studs are perpendicular to the face of the bracket after you have verified the brackets are square and planer.

On edit; If your bracket tabs are not on the same plane and one is bent out of line you run the risk of breaking the MC as you tighten things and try to bend the MC to sit flat on the brackets.

Thanks, all!

I will do better at checking the alignment to see what's bent.

Now, if it  is the stud that's bent, do I still have options?

a pc of pipe over the stud, with the bracket mounted in a vice, would make for an easy adjustment

The stud is clearly bent. Bend it back with something that doesn't smash the threads. This is really a very small simple fix.

The best too for that would be a coupling nut--it'll cover and preserve the threads. Put another on the other stud, make sure they both have flat facing the same way, and use that as the plane to straighten it to. With the nut on it, you can whale a bit with a hammer with no fear of damaging threads.

I did this yesterday for a similar--but completely different--bracket with one bent stud and leg.

Put a nut on it and give it a little tappy tap, simple.

I too thought about a coupling nut. In fact, if you can thread it on, the act of putting a coupling nut on it might do some straightening all by itself. However, I did worry about galling the threads trying to screw the nut on.

I'd only go as far as it screws on by hand for the same reason.

On the bracket I was fixing (handbrake for a wheelchair), the two studs were supposed to be parallel, with the bracket at 90 degrees to them. It was pretty well mangled, but by using the coupling nuts, I could clamp the two studs in a vise and then whale away on the bracket until I had everything back where it was originally--within tolerance.

Heat it, bend it. Use a 3/8 deep well socket or whatever fits tight on the stud, attach an extension and tweek it. It's not a internal engine part.

Run a straight edge on the bracket first.
Straighten this first if it is bent.

Then use a 12inch "portable lathe" [Aka Crescent wrench] on the stud and carefully lean on it.
I find the wide flat jaws on the crescent wrench does almost no damage to the threads.

Chase the threads with a thread cleaner die after.
