Cylinder Block Assembly
Expansion and Pipe Plug - Installation
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 LoctiteTM 277 around the outside
diameter of all expansion plugs before installing.
