Challenging Cast Iron Welding Repair | Tractor BROKEN Differential Housing Rebuild (Part 1)

Challenging Cast Iron Welding Repair | Tractor BROKEN Differential Housing Rebuild (Part 1) This video documents a challenging cast iron welding repair on a broken tractor differential housing, showing the real workshop process behind saving a major drivetrain component that many would consider scrap. In Part 1, we carefully inspect the damage, locate and mark the cracks, and prepare the surface through cleaning, grinding, and proper preheating to reduce stress in the cast iron. You’ll see the first stages of the welding and metal buildup process, where heat control and technique are critical to avoid further cracking. This type of repair is common in heavy equipment and farm tractor restoration, where replacing large cast parts is costly and skilled welding can bring them back to life. If you enjoy real-world mechanical repairs, tractor rebuilds, and detailed workshop processes, this series will show how patience, experience, and the right methods can restore even severely damaged components. Part 2 will cover final welding, finishing, and reassembly.
