Connecting rod bearing set (8 pcs) KS 87739630, 0.75 mm undersize, for Mercedes-Benz inline six-cylinder engines M114 & M130 from 1/1970.
NOS – never fitted · Genuine Kolbenschmidt · 0.75 mm undersize – repair stage III
Condition of this part
NOS in the original Kolbenschmidt box, unused, no running marks on the sliding surfaces. One shell shows a few dark spots on the steel backing, the box shows worn corners.
Function and location
Connecting rod bearing shells are the split plain bearings between the connecting rod and the crankshaft's big-end journal. They run in an oil film, absorb the piston's gas and inertia forces, and set the bearing clearance. The 0.75 undersize means the shells are thicker-walled than standard and belong on a correspondingly ground crankshaft.
They are installed in the lower connecting rod eye, one shell each in the connecting rod and the rod bearing cap, on the crank pin of the inline six-cylinder's crankshaft.
