Connecting Rod: Description and Operation

Connecting Rods:
The connecting rods are of the same design as on the M60 engine.

For the first time on the M60 engine and now also on the M62 engine, sintered metal connecting rods are fitted. In addition to the lower weight (moved masses), these connecting rods offer high strength over the entire output range of an engine.

The connecting rod and the big-end bearing cap are separated during manufacture of the forged sintered connecting rods. This renders conventional centering by means of fitted dowels during assembly unnecessary centering is achieved by means of the break structure and the guide for the connecting rod bolts. Taring (colored dots or identification numbers for the weight class) is not necessary thanks to the high production accuracy achieved in the sintered forging process

On the M62 engine, new antifatigue bolts are used to secure the connecting rod to the crankshaft.
