## 🔌 Function

The bearing pair supports one connecting-rod big end on the crankpin oil film and carries alternating combustion and inertia loads.

## ⚠️ Common Signs of Failure

-   Deep knocking is heard under load or during acceleration
-   Bearing clearance exceeds specification
-   Shell overlay is scored, fatigued, wiped or heat-damaged
-   Metallic debris is found in the sump or oil filter
-   Crankpin repair size and installed shell grade do not match

## 🛠️ 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
