Welding a rod to it, I don't think will work. I know it was tight in the hole, so it will not turn out easy. The small weld would probably break off :(
I tried using a punch to turn it out but no luck.
Another method could be annealing the broken stud until cherry red and then letting it cool slowly but that would surely cook the Viton seal and possibly damage the bearing.
One method I think I will try it to dremel a hole inside the stud and then use the easy out extractor.
Wish me luck.
If that doesn't work, I will either send it to Bill or order a rebuild unit from INTENSE, that has the end also turned for smaller than 2.8 pull
I know I will not get a full refund for the deposit and will probably cost for someone else to repair.
I want to do this right.
The project I am doing at my job now involves installing a new Papermachine headbox approach pipe that is polished to an electropolished quality. Some of it is what is termed "Cottonball finish", that is polished to a shine so if you wipe a cotton ball across the surface, it will not pick up any fibres.
Try that with your stock cast aluminum manifolds
It would rip the head off a cue-tip.
I only have one hour since I've been home from work to go to sleep so I can get up at 4:am for another double shifter, so have to keep my posts short.
