Full Description: *

On the front of the left hand jacket core, the product design doesn't allow for a flat surface for blowing/tamping of the core. The irregular surface created by this design has contributed to the thin wall leaker scrap that occurs in this area on the casting (hole 131). Alter the design on the F jacket core to the design shown on the attached pictures. This design will provide a flat surface for the tamping pin and blow tube for that area. UG files are ARG76440/001,ARG76439/001, and ARG76438/001.
