🔌 Function

The bearing shells form the replaceable running surface between the connecting rod and crankshaft journal, maintaining the specified oil clearance while carrying combustion and inertia loads.

⚠️ Common Signs of Failure

• Low engine-oil pressure or metallic knocking
• Copper or bearing material found in the lubricating oil
• Excessive big-end oil clearance
• Scored or heat-discoloured crankshaft journal
• Bearing seizure, shell movement or connecting-rod damage

🛠️ Service Notes

• Fit the shells dry into clean, dry rod and cap housings with the locating tang in its notch, then oil the running face only — oil or dirt trapped behind a shell stops it bedding and carrying heat away
• Never file, scrape or dress the shells, the backs of the shells or the cap joint faces; the crush that locks a shell in place depends on those faces being untouched
• Measure the crankshaft journals and check the clearance you actually have, with a crush-type clearance gauge or a bore gauge and micrometer, against the figures in the workshop manual for your engine — a scored, worn or oval journal will destroy new shells
• Keep each pair of shells with its own rod and cap, refit caps the original way round, and read the wear pattern on the shells you removed; it usually tells you why the bearing failed
• Renew the rod bolts where the manual calls for it, tighten by the specified method and sequence, and confirm the crankshaft still turns freely by hand before going any further
