Slicer belt replacement. I'm stumped

I just snagged a Berkel 919 slicer that has the automatic option. That function doesn't work because it has no belt, so I grabbed a new one to install. Anyone with a Berkel slicer have any idea how to do it? There are some (terrible) instructions online in the manual, but they are not very useful beyond the pulley diagram.

Thanks! I had seen that. Entirely different slicer, though. I'm looking to replace the clear belt that allows hobarts or berkels to be used in auto mode. Thanks, though!
