Metal Spray REPAIR Caterpillar Engine Crank Pulley | Thermal Spray Welding

The seal surface of this crank pulley is badly worn and we’re going to repair it with metal spray! This crank pulley is off a Caterpillar 3306 Engine from a CAT 637G Scraper tractor and the seal surface has a deep groove worn into it that needs repair. We show the step by step process of metal spray welding using our Castolin Eutectic Rototec setup. First we prep the part by machining down the worn surface and apply the masking compound. Then we use our metal spray gun to pre heat the part before spray welding on the new material. Once the part has cooled we machine it down before finishing it to spec using emery cloth.

In this video we are using:
- Hafco TM-1740G Centre Lathe
- Castolin Eutectic Rototec spray gun
