Description Of Change: The following improvements have been made the reman engines:
- Controlled the supply air dew point and cleanliness to lower metal spray porosity variation to ISO 8573 Class 3.
- Added the application of Diamant® Dichtol WFT (1532) metal spray sealer to all sprayed surfaces.
- Implemented a new thicker (in pre-machined state) sleeve with tightly controlled circularity. This prevents the sleeve from flexing during top deck machining.
- Implemented the use of liquid nitrogen to freeze the sleeve. This allows for a slip fit between the sleeve and the cylinder block.
