splitting intake and exhaust manifolds

Don Scieszinski

The four long bolts are nearly welded and heads
are missing shoulders even vice grips won't grip
on to loosen. Any advice on how to split them?

Oh yeah, they can be tough. Cut heads off and hope you can pull manifold apart. If it does come apart then I heat threaded area red hot and use vise grip or pipe wrench slow and careful. After they break off (hmmmm) weld a nut on to remains to try that method.If that fails, then start drilling. I would take it to a machine shop. If and when you get it apart be sure to repair the heat riser mechanism and clean all that crud out of the exhaust passages around the intake heating chamber. The passages go all the way around inside. CaseIH has all the bushings, plate , shaft, and spring available. That is the secret to help out the cold blooded nature of these tractors.
