does anyone have a diagram for roller/drive belts empress 16?

does anyone have a few pics or diagrams of the reassembly of a mountfield empress 16 86302 1997 model. I had to replace the clutch and throttle assembly and have gotten in a twist about how the drive belt roller drive goes back together. I keep getting the small white roller wheel on the wrong way and can't see how it goes back together. There is a plate that swivels when the clutch cable is pulled to lower/raise this wheel to tension the belt..if pos..if anyone has a mower like this could you post some photos of this end of the mower..
much appreciated
