Removing Broken Exhaust Bolts the Right Way | Farmall 460 Manifold Heat Exchanger Explained

This is a hands-on shop session, not a buyer's overview: Matt disassembles the Farmall 460's two-piece exhaust manifold, explains how the heat exchanger's thermostatic flapper valve works to warm cold intake air, deals with rusted/buggered threads, breaks and then drills/extracts a stubborn bolt, and taps the hole clean. Good for owners tackling their own exhaust manifold repair or wanting to understand this heat exchanger mechanism in detail; not a tractor overview or buying guide.

An owner-operator (Matt) documenting his own repair work on his Farmall 460 as part of an ongoing shop project series.
