Thrust bearings are used to control end play in the crankshaft. End play is important because it limits the fore and aft movement of the crankshaft in the block. If an engine is assembled with too much end play in the crank, or if the thrust bearing fails, the forward movement of the crankshaft in the block can chew up the main bearing caps and ...
