Ford 981 Diesel manuals

I just bought a Ford 981 Diesel and now I need a set of manuals for it. What manuals do I need since it has the selectospeed transmission? I am looking for a parts book and a service manual but if their is supplemental manuals for the diesel engine and sos transmission I would like to know about them.

Reprints of the parts manual for the Ford '4 Cylinder Tractor - All Models' 1953-1964 are available reasonably priced. I got one off eBay from 'Peaceful Creek', they have reprinted many publications surrounding many brands/items. I believe you can get 901 series operators manuals from them also.

The I&T FO-20 has information and R&R instructions on the tractor and the SOS transmission.

There may well be some specific Ford SOS material from back in the day, I'm not sure. Likely someone here will know.

If it has the original Over Running Clutch (ORC) S-O-S transmission, then the manual that Pomester mentioned will cover everything. If it has the updated Direct Drive Clutch (DDC) S-O-S retrofit, then you will need the "2000/4000 Select-O-Speed Supplemental Service Manual" to cover the later DDC transmission.
 
(quoted from post at 20:14:17 12/29/20) Do you have casting numbers for the
different transmissions? Or an easy way to
tell which one you have?


Tucker, an easy way to tell is by the cover. The original is rounded evenly all the way across, while the second gen looks like the right side is cut off at an angle.
 
Very nice looking tractor, Ya done good! For the original manual reprints Jensales sells them. Pricey but they are all inclusive and nice to have.
