If your talking about the crankshaft in the engine cases. Then no. little to none. If there is your main bearings are likely shot and you will soon find up and down play as well. I find the main bearings dont actually last as long as one might think. ( compared to wheel bearings on a trailer, wheel bearings on your pickup etc) My engine runes just fine has great compression but the main bearings are giving it up. maybe its just my specific engine but im finding up and down play at the flywheel. it still runs but is in desperate need of a rebuild because of that reason. However side to side play in the ROD. on the crankshaft is normal. up and down play in anything in the rotating assembly. wrist pin, upper and lower rod bearings, or the main bearings is going to cause you major trouble shortly if you dont correct it.
