REMOVAL AND INSTALLATION (Continued)
Installation
CUP Type
Expansion-Type
Cup-type core plugs are installed with the
flanged edge outward. The maximum diameter
of this plug is located at the outer edge of the
flange. The flange on cup-type plugs flares out-
ward with the largest diameter at the outer (seal-
ing) edge.
It is imperative to pull the plug into the ma-
chined bore by using a properly designed
tool.
Under no circumstances is the plug to be
driven into the bore using a tool that contacts the
flange. This method will damage the sealing
edge and will result in leakage and/or plug blow
out.
The flanged (trailing) edge must be below the
chamfered edge of the bore to effectively seal
the plugged bore.
If
the core plug replacing tool has a depth
seating surface, do not seat the tool against
a non-machined (casting) surface.
Expansion-type core plugs are installed with
the flanged edge inward. The maximum diame-
ter of this plug is located at the base of the
flange with the flange flaring inward.
It is imperative to push or drive the plug
into the machined bore using a properly de-
signed tool.
Under no circumstances is the plug
to be driven using a tool that contacts the
crowned portion of the plug. This method will ex-
pand the plug prior to installation and may
damage the plug and/or plug bore.
When installed the trailing (maximum) diame-
ter must be below the chamfered edge of the
bore to effectively seal the plugged bore.
If the core plug replacing tool has a depth
seating surface, do not seat the tool against
a non-machined (casting) surface.
