Oil Passage and Oil Seals in a Crankshaft

The crankshaft oil passage passes oil from the main bearing journals to the large end journals. Usually, the hole is drilled in the crank web. When the crankpin is in an up position and combustion forces push the connecting rod down, oil can penetrate between the journal and the bearing. The crankshaft extends slightly beyond the crankcase at both ends. This will cause oil to leak from these ends. Oil seals are provided to keep oil out of these openings. There are two main oil seals connected at the front end and the rear end.
