NOTE
When grinding out minor nicks, abrasions, or cracks on connecting rod,
make sure ground areas form smooth contours with adjacent unground
areas.
22. Connecting rod
Repair minor cracking in the transverse direction
(across flow lines) of the connecting rod as long as
the cracks are no longer than 0.50 inch (12.70 mm)
and can be completely removed by grinding no
deeper than 0.0156 inch (0.3969 mm). If the
cracking extends over the edge of the H section and
on both sides of the connecting rod flange, the crack
must be completely removable, by grinding no
deeper than 0.0050 inch (0.1270 mm). Otherwise,
replace connecting rod in either case. Minor
cracking in the longitudinal direction (along flow
lines) may be removed by grinding no deeper than
0.0313 inch (0.7938 mm). If crack is deeper,
replace connecting rod. Remove rust and treat in
accordance
with
