I need a diagram for a G5200 belt installation. 501880401

So I had to do some digging… This appears to be the Craftsman 5200 based on the pictures: https://www.sears.com/craftsman-48-in-tu… From that webpage, I found the operator’s manual: https://i.sears.com/s/d/pdf/mp-tc/100917… On page 27 of the pdf on the operator’s manual, you’ll find a section called “To Replace Mower Blade Drive Belt” with the following diagram of the belt routing:

Of course, this is all assuming that my digging is correct, and your riding mower is model# 917.204070 .
