The older AM14U pdf seems to have the Part number mixed up with the belt number of teeth. Unfortunately, I did not have all the right parts in front of me (belts and AM14U2 chassis) to absolutely answer the question properly and ended up ordering extra belts.

So, yes. I think there is an issue. My recommendation is to call Andy Mark to resolve it. They are of course, very helpful.

Have a great season!
Just called AndyMark and spoke with an engineer there. It appears that on this chart, using the 151T belt works in the square configuration if using the outermost green hole. The representative said another option for 6" wheels is to use the inner red hole with the 131T belt if more wheel clearance is necessary.

I guess even though we messed up and ordered while referencing the wrong diagram, it appears that the 151T belt will work as long as there is enough space on the end. Otherwise, we can default back to the 131T belt which is included and use the inner red mounting hole.

EDIT: Even though we don't have the belts yet, it appears as if there is enough clearance to use that mounting hole! (albeit very little)
