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 dimen-
sion.
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.
