MF135 Broke the bolt

The only additional one I have is to try an EZ-OUT.

Lots of people I talk to just hate those things, and I did too! They NEVER worked! That is, until I actually read the directions.

The trick that I discovered is to use exactly the size drill called for on the tool. It's usually printed (stamped) on the side of the tool. Just drill it out as close to the center as you can, tap in the EZ-OUT, soak it with solvent (a day or two would be nice) and gently back the stud out. It always works for me, now!

After you replace the studs, be sure to use readily available brass double thickness nuts. If you do, the job will be a snap next time.

Though it is after the fact now, had you heated the nuts cherry red and/or used an impact wrench, it is likely that the nuts would have loosened.

my suggestion: try to grind away one side of the nut with angle grinder or Dremel tool, then use small sharp chisel to get rest of the nut off, that will get your flange off

likely have to heat 2 remaining studs to get them out of the maniford, don't let the torch ruin anything down under there, that gives you bit more room to work

if you are lucky, some of that broken stud will be sticking out, get it cherry red and see if channellocks will get her loose

this job is lot easier with manifold off tractor and in a vise but that makes it whole different job
