(a) Check connecting rod bearing bore w;th a bore dial indicator against limits specified in re- pair standards (table 3-8). {b) Check rods for ccks and for twisted or bent condition. Bent or twisted connecting rods must be replaced. Under no circumstances should connecting rods be straightened. Destroy any rod found damaged to insure it will not be reused in an engine. (c) Check dimension between centerline of small and large end bores (fig. 3-175). This dimen- sion must be 10.998 to 11.002 inches. Destroy any rod that does not meet this limit to insure it will not be reused in an engine. () inspect piston pin sleeve bearing for pit- ting, galling, scoring, or discoloration.
