Hello Everyone,
Looking for advice on extracting/repairing some snapped exhaust studs...
Case 580D Backhoe
There's 5 separate studs that need removed, all snapped off below the surface of the head. I'm trying to decide if I try to drill & extract them or if I should just drill out oversized and used a thread repair insert?
God knows how long the studs have been sitting in there rusting themselves in place. They were snapped when I bought this thing and that was over 5 years ago. I'm afraid the extractor is just going to snap off. My thought is just skip trying to extract them and skip to just drilling out and use a thread repair insert but I'd like to hear the advice out there first.
Do I need a cobalt or carbide drill bit for this or will anything that isn't chinesium HSS work?
