I don't know how the Dina is setup, on a MCI with the 12.7 series 60 they are a bitch to change even without a waste gate

It looks to be bad on a Model 15 Eagle as well.

If you are handy with a torch, you can heat the nuts bright cherry red and turn them out with a wrench. If it starts getting real tight, reheat red and repeat. I've removed nuts from chevy exhaust manifolds where the stud was rusted down to 3/16 dia. above the nut sucessfully, frequently.

The design of the Dina is such that getting to the turbo is not bad by removing some side panels.

Has anyone actually replaced the turbo studs on a Series 60? Are they threaded into a hole, or do they have a nut on back? (Don't have access open to turbo right now.)

Can a MAPP gas torch with real MAPP gas get the nuts hot enough?

The are threaded in the center section of the 3 pc manifold ,Mapp gas is a waste of time don't over think it may come off easy without heat and the studs are good

The nuts and studs seem to be quite rusty so I expect a fight. What size impact socket do I need?

Soak studs several times over a couple of days. After the first day, carefully wirebrush the nuts and threads protruding above the nuts to remove any rusty residue, then spray a couple more times. A torch would be nice, but you may not have one. You can try mapp gas torch, but it must be able to get them bright red. I would use a wrench or socket and ratchet. Am impact wrench could snap off the studs, when finess with other might get them off. If nuts are rusted that your socket wants to round off, try a metric socket. Some are between uss. Sizes and may work. You may have to help the socket seat on the nut with a couple light hits with a hammer. AVOID usuing 12 point sockets. They will easily round off a seized rusty nut. If you have room, you can split the nuts with a small sharp chisel. Good luck!

Looks like only a 1/4 inch of stud sticking out of the nut on mine, which is a plus if yours is the same.

I am really doubtful that a mapp torch could get it that hot. But it would be better than nothing if that is all you have. Try to use a 6 point socket and have fun!

I looked closer tonight and things are not as rusty as I thought. I only have a little bit of stud sticking out like yours. I put some PB Blaster on tonight.

If the metal gasket that came with my Reliabilt turbo is bent should I replace the gasket?
