Hi I'm looking for info on replacing the mower belt on this unit. I have the belt, but need to know, maybe a diagram, on how to install it on the pullys. Any help greatly appreciated. How to find a manual would be great to. Thx

You could try mtd.com for a manual, or a local mtd dealer. As far as replacing the belt, the flat, back, or outside of the belt whichever you want to call it, goes against the flat sided idler pulleys, the "v" side goes to the "v" shaped side of the pulleys.
