Ok After arriving at a customers place via the shippers it seems the shippers brutalized it and now has a shaft seal leak. does any one have any old scotsman service manuals that has the info?

Info of machine:

Refrigerant: R-12
Model Number: AF1AE-1D
Serial Number: 194729-07J

There seams to be a great lack of info out there, I found it once which had basic data. But now need repair info, it is a bottom drive augar.
