I get the feeling that the pin has been pulled on the grenade. I don't know what sort of transaxle the 160 has, but it was a similar story that I got from the fellow that sold me the craftsman. The torque actually caused something to bind up, then it cracked the case.
I'd say get one of the other units in the fleet operational, regardless of appearance. If you keep running it, it will likely just get worse, causing more damage and cost more to fix.
