Figure 5-2 Connecting Rod Identification
Refer to Figure 5-3.
A redesigned connecting rod assembly with an
added alignment sleeve feature was introduced
into E7 production engines in April 1995. This
connecting rod assembly has two alignment
sleeves (3), one sleeve in each capscrew hole of
the rod cap (1) to locate and align the cap and rod
thrust faces. These sleeves provide the best
alignment when sleeve gaps are positioned at a
location approximately 90 degrees to the tongue
or groove (2). The sleeve gaps must not be in line
with the tongue or groove.
