I ask because when I was a kid I had a kart with a friction clutch (basically two pieces of steel with a sprocket sandwiched between them on the crankshaft, when "in gear" a lever/bearing pushed the sandwich together and made the sprocket turn). It worked well, but ate crankshaft bearings with the side load.
Yes, zero thrust load on the crank with this clutch.
