The box shows clear signs of storage: crushed edges, torn lid, broken adhesive seal, yellowed sticker. All 14 shells are unused: the 12 base shells carry the factory dark preservation coating on the steel back, the running surfaces are clean and free of scoring; the 2 flanged bearing shells are bright and shiny with sharp markings. Date codes 02\/1998 (base shells) and 05\/1997 (flanged bearing).

Two half-shells each form a bearing point; via a pressure-fed oil film they carry the entire combustion and inertial force and keep the shaft precisely centered. The groove and bore of each shell feed engine oil into the bearing clearance and on to the connecting rod bearings. The one pair of flanged bearings additionally absorbs the axial thrust, thereby limiting the crankshaft's end float when the clutch is engaged.\u003c\/p\u003e\n\u003cp\u003eThe shells sit in the bearing bore of the crankcase – one shell in the block, the mating shell in the main bearing cap. The BMW inline six-cylinder has seven bearing points.
