How is the deflection of the crankshaft affected?

Crankshaft deflection is affected by several factors in addition to cylinder pressure. These include the structure of the block and crank along with the strength of the bearings, the bearing clearance and the condition of the oil film.

Is it true that cranks are less likely to fail?

One of the most common myths is the belief that .010”/.010” shafts are less prone to fail than the ones that are ground to .020” or .030” undersize. Although this idea was once based in fact, it’s no longer true. We’ll take a look at the difference between the past and present, but let’s talk about what causes a crank to fail before we go there.

What makes a crankshaft shorten the life of the engine?
