gear box removal v6

[sinkunit0]

i,m trying to take the gear box of an old bridgeport. it quite badly corroded.
the two nuts on the front of the box in the recess between the cav plates have been put on without washers and have also been slightly rounded off. i,ve cut a spanner down to try and get in behind for a better grip but it did,nt work and theres not enough room to get a ring spanner over the stud. how can i get these off and drop the gear box off

If a nut that I'm trying to remove is badly corroded and is in a recessed area I soak the bolt/nut in penetrating fluid first then use a propane torch on the nut/bolt as those nuts should be nylockers, applying heat will melt the nylon and make removal a bit easier. If the nut is in a condition that the standard socket that fits normally spins I go to the next size metric socket knowing that when I beat it on its not usable again. Most of the time that works for me.

Good luck,
Jay @ JSRE

...'nother tried and tested method... take a nice sharp 3mm drill and drill a couple or 3 holes in a vertical line on one of the flats of the nut.. then take a nice sharp cold chisel and give it a good sharp tap.... splits the nuts..

Sounds painful.
