Sorry, typing in a rush... I thought that's what they were discussing if the taper is not correct, the clutch would be off centered on the stub? Was thinking "laterally" (across the engine) stress if the bolt was tightening and being stretched away from the engine, but actually that should have really said torsional I guess if the theory is the bolt is tightening, and yes, it would be axial directly along the plane of the bolt.
If the engine is running and crank slips in a forward rotation, with the clutch and bolt stationary, would the bolt not then be over-torqued and stretched? Or are you referring to "movement of the taper" as in/out towards the engine, along the crank? Not critiquing, genuinely trying to understand.
