Missouri | The plastic wheel doesn't carry any load. It's a wrap spring clutch design, the plastic wheel just stops the leading edge tang of the wrap spring when it is engaged by the air cylinder piston.
When overloaded, they will slip. With enough slippage, there will eventually be breakage. The clutch will not break a #41 chain.
If you put a 7/8 socket on a torque wrench, and bind up the output side of the clutch, you could see for yourself what torque level the clutch yields at.
If driven continuously at a torque near the yield strength of the clutch, I think the most likely failure mode would be breakage of the wrap spring, but that is purely conjecture, I haven't seen it done. | |

Tru-Count air clutch, how strong are they?
