4120 repair manuals

[Double6]

I was wondering if anyone knows which JD part numbers would be for a engine/fuel system repair manuals for a 4120, with JD's parts system you can't just put in 4120 repair manual & hit "search" you need a JD part number.
Thanks.....

The part number for the correct repair manual for your tractor depends on the serial number of your tractor.
