I know these cases have a life cycle (if you want max performance). If you have a spare used crank (looks like this one is toast) I would sat to slap it together as a spare. If you have to buy a new crank I would say buy new cases as well. I think the motor will run with those cases, but it will be marginal, and you will hav extra risks.
