Logically, it appears that taking the tensioner apart, replacing the spring and resetting the ratcheting should do it. I was thinking this would be the normal procedure when rebuilding the motor or replacing the timing chain. One could go ahead a buy all new parts but sometimes that's not practical or even necessary.
