Repairing Parts for 2000HP Engine! | Machining & Liquid Nitrogen

We need to repair a pallet of parts for a 2000HP Caterpillar 3516 Diesel Engine. These are some of the exhaust components from the engine that came out of a CAT 789 Haul Truck. The parts are made from cast iron and over time they have worn out. We show the step by step process to repair the exhaust parts including machining in the lathe, boring in the milling machine and shrink fitting new sleeves using Liquid Nitrogen. We're going to give those sleeves a 0.2mm (8 thou) tight interference fit because we definitely don't want them getting out and into the engine!

In this video we are using:
- Hafco TM-1740G Centre Lathe
- Hafco TM-26120G Centre Lathe
- Hafco BM-63VE Milling machine
