Have Hoover wind tunnel U5475-900. My belt keep breaking I am using the right size 38528-033-E. Is there a picture in a manual which shows the exact way to change a belt. As far a I know there is only one possible way to change a belt for this model. Before I pitch the vaccum cleaner all together I want to make sure there is not another way to change the belt. I woudl appreciate any help. Thanks
