To remove a large core plug, drill a 12.70mm (l/2-
inch) hole in the center of the plug and remove with
an impact Slide Hammer T59L-100-B, T50T-100-A

a small core plug, drill a 6.35mm (1/4=inch) hole in the
center of the plug and pry it out with a small pin
punch. Clean and inspect the plug bore.
Prior to installing a core plug the plug bore
should be inspected for any damage that would
interfere with the proper sealing of the plug. If
the bore is damaged it will be necessary to true
the surface by boring for the next specified over-
size plug.
Oversize (OS) plugs are identified by the OS
stamped in the flat located on the cup side of the
plug .
Coat the plug and/or bore lightly with an oil-
resistant (oil galley) or water-resistant (cooling
