The LO does get at least one thing wrong. The NP 205 does NOT hold 5 quarts of dextron.

The power steering for the front wheels should come from the standard chevy pump located low on the drivers side of the engine. You can almost see the filler cap in your first pic (post #4) below the thermostat housing.

Still researching, but I fid find a very old thread that you may find useful. https://www.steelsoldiers.com/threads/aircraft-tractor.2779/page-2

I have found an NSN for the truck. Nsn 1740-01-164-0513

Ok, cool. It is a civ version of the truck. Only one alternator. The pump that failed is for the rear steering, I do not know if the rear steering hydraulics interconnect to the front steering. Is there a separate tank for the rear steering?

NP205 still takes dextron. in the-12 Lube Order it will you find the front diff requires an additive. Readily avail at part stores.

MFR 55683 is wheeler brothers. Still listed on the internet. 19954/FR17270-41 is how I read the part number. Not having any luck with that yet. Still no luck locating manuals so far. Data plate pictures will help with that. Also see if the sticker in the glove box is still legible, it may help also.

Please show us where it mounts. Also, pictures of any data plates, usually inside the drivers door frame. Thank you.

Welcome! With an 86 M1031, you should have the PTO driven generator. You will have an NP205 transfer if it is PTO driven. upload some photos of the truck.

Back in place and bolted down now.
