I changed my tensioner and the water pump recently. I did it myself and I could see no way to remove it without taking out the fun clutch. By the way, I had a difficult time taking out the clutch, since it turns when I tried unbolting the main bolt that holds it in place. You will have to find a way to keep it from spinning when trying to loosen the bolt that holds it in place, not an easy thing without special tools, but it can be done with some ingeniouty. It took me quite a few hours.
