1. The first step is to disassemble the core engine and visually inspect the Cylinder Block, Crank Shaft and Cylinder Head castings. If they pass this step they move on to the next step the Thermal Cleaning.
2. Thermal Cleaning in this step the disassembled Cylinder Heads and Block Castings go through the first cleaning step in which they are heated in a flameless oxygen depleted enviroment to 650 degrees to prevent cracking or warping while burning off sludge, carbon and oil residue.
3. In this step the Cylinder Head and Block Castings are sent to a Steel Shot Blast Machine where they are blasted with Stainless Steel Shot pellets that leave a like new finish on all surfaces of the Cylinder Head and Block castings and stress relieves the castings.
4. Now we magniflux the Cylinder Head and Cylinder Block castings to insure no cracks or casting faults went unnoticed.
