Need some advice. Flat-head bolts, down flush in a countersink, about 19-21? mm, with a 14 mm allen socket. (Kobelco sk250). Need to drop at least half of the split pan to fix a track drive hydraulic leak. Have broken two 3\4"-1\2" drive adapters (one with a breaker and cheater and one with a 1'" burp gun). One of three bolts came out. Can't torch out an access hole because the pan has flammable hyd. fluid, hoses, and the usual mouse nests in it. And no other access to extinguish even a small fire. Torching, drilling, or grinding the heads off down in the c'sinks makes it extremely difficult to remove the remaining bolt portions. We heated the bolts up to "red" just before quitting tonight. Hopefully hot enough to release red loctite if that was used previously. If that doesn't do the trick, then WHAT NEXT?
I may be able to weld a large nut onto the flathead or cut the heads off and plan on welding the pan on at reassembly (not the best option, I know). Any good advice out there? At least it's on a clay pad with decent weather forecast tomorrow. It could be belly deep in mud, ice, and snow. Or worse!
