Confused about thrust washers

I don't REALLY understand what they do?

 

Basically keeps the crankshaft from moving back to front.

 

In what application?

 

Fair simple, really. Whenever you have a shaft that turns, there is always some sideways force (thrust), sometimes strong, sometimes weak, depends on what the shaft is asked to do, mostly.

To acommodate this sideways movement, there are thrust washers and thrust bearings. The washers are for the light forces.

joe--h, thrust WASHER on the crankshaft of a HAMB-friendly engine? Thrust bearing might be what you meant. If so, it limits movement of the crankshaft in the block, and also gives a thrust surface for the crank to bump against when the clutch is depressed in a standard shift car.

 

Cosmo is right. They are like bushings for axial movement.

 

thrust washer in a trans does the same.. what was your question? what application?

 

Google?
