Expansion
and
Pipe
Plug
Installation (1-06)
All expansion plug bores in the block are machined to a
standard english dimension (i.e., 11/16 in, 1-1/4 in,
etc.). To achieve the correct press fit of the expansion
plug in the bore, the expansion plug must be larger than
the bore diameter and the expansion plug driver must
be smaller than the bore diameter. Therefore,
expansion plugs and their drivers are not made to a
standard english dimension.
The plug drivers are called out by the dimension of the
bore they are to be used on (i.e., a 1 in driver for 1"
bore). The expansion plugs are called out by Cummins
part number (a dimension is also listed for reference).
Apply a bead of Three Bond, Part No. 3823494, around
the outside diameter of all expansion plugs before
installing.
