Where is the thrust located in a crank endplay engine?

This makes crank endplay a spec that cannot be overlooked, and that alone should motivate all but the laziest of engine builders. We will be using both a small- and big-block Chevy for the images in this story, but the process is the same for all engines even when the thrust is located in the center main bearing as with Fords and the GM LS.

Why is crankshaft endplay important in a car?

It’s all the checking and clearancing that is essential before the engine is assembled, where all the real effort is located. Crankshaft endplay never seems to garner the same level of attention as say, rod and main clearance, but even with its somewhat limited attention, this is still a crucial area.

What happens if crank endplay is not checked?

If nothing else, if crank endplay is not checked and verified, the end result will be disassembling the entire engine to repair the damage, because too loose is just as bad as too tight. This makes crank endplay a spec that cannot be overlooked, and that alone should motivate all but the laziest of engine builders.
