Semicylindrical bearing shells (12) are mounted with their radially outwardly facing semicylindrical surfaces (14) against a mating surface (16) of a bearing cap (18) or an engine block (49). Such shells (12) have previously been held against rotation by tab and slot arrangements. They have either not been held against falling away from the mating surface (16), or screws have been centrally affixed through the shells (12) and into the bearing cap (18) or block (49). Such screws have interfered with proper lubrication of radially inwardly facing surfaces (20) of such shells (12). The improvement herein includes a pair of indentations (22a, 22b) in the outwardly facing surface (14), one at each end (24a, 24b) of the shell (12) and a pair of abutting indentations (28a, 28b) in the mating surface (16). A pair of members (30a, 30b or 30'a, 30'b) are held in respective shell indentations (22a, 22b) and abutting indentations (28a, 28b). The members (30a, 30b or 30'a, 30'b) hold the shells (12) against the mating surface (16). |
