Can we fix this cracked cast iron transfer case housing!? This housing is off a Caterpillar 966K Wheel Loader, there are multiple cracks through the bolt holes into the housing so we’re going to have a go at repairing it! Repairing cast iron is always a challenge because of how ‘dirty’ and brittle the cast iron material is, and repairing a large and thin housing is one of the most challenging parts to try and repair. For the repair we will be using our preferred method of metal powder and jet flame spray gun with oxy acetylene. We also show the process of dye penetrant testing to show the cracks and grinding them out before using flame spray welding. Will this repair work or fail?!

In this video we are using:
- Dy-mark Flawchek dye penetrant system
- UTP Variobond flame spray gun
