Interesting point. On my car, I can disengage the assembly as shown in Fastlane from the tensioner with the tensioner in place. Difficult as heck to get it reengaged in situ.

If the rivet is broken, I imagine the rod could be lifted off the engine, right? With the rivet in place, the tension adjusting rod won't go far from the tensioner.
