Hi Huys,

My brothers bike has broken studs and we removed the head and tried to remove the broken stud. it seems the previous owner might have used epoxy or some other stuff as the screw extractor broke off "no it was not my fault" and the drilled hole was straight as we removed it from the engine and used the bench drill "also welded before with tig a nut to it but it didn't worked out and it broke". So now the solution seems to change the head. Do you guys know if the heads there are on jpcycle or on the Harley sites need any work to be done or it just need to be mounted?

If you plan on just getting rid of head take it to a machine shop to get repaired or keep increasing drill bit size until you can get it out. Or drill fill and tap.

 

i don't have the money to send to the mechanic and i already removed it from the engine. Harley shop asked 1800$ to do it without the head part.

I am asking if anyone has the knowledge to advice on: do i need to do extra work on the head if i get the harley parts, or it just assembly and no extra work to be done.

thanks all for the help

I would ask who ever you are buying it from, they should know.

 

i am buying from harley. i thought maybe someone around here had done that job by himself, and could share it.

You never, ever, ever, try to remove a broken exhaust stud with an extractor. It has a 99.999% chance of breaking off inside the stud, and a .001% chance of successfully unscrewing the stud.

The studs have an interference fit thread on that side of them. It's designed to bind up in the head. It does a mighty fine job of it, too. Nobody put any epoxy in it or anything like that. It was bound up by design.

There's a drill jig available for drilling out a broken off stud. It's the best way to fix that problem.
