1957 ford 640 tractor

I"m sort of embaressed to write this. I need info about fluids. I know coolant and engine oil, but i need someone to inform me of all the other fluids and exactly where are the "check plugs", the "drain plugs", and the "fill openings". I need to chage all the fluids because I have way too many years and hours on the present fluids.(2) I also need to know the type and weight of the fluids, is it hydralic fluid, gear oil, or just plain oil?. Are there different oil and resivoirs for the tranny, the rear end, the lift, the PTO? It would be ok if you just directed me to a place with all this info. I cant afford a shop manual, and the old man who used to work on it passed away. He knew more about those tractors. He worked on them for 50 years. He told me all this stuff but i did not write it down and i am old too and my memory is just not good enough. Thank you so much. Shelby from south Georgia

It's very simple. Put motor oil in the engine, and universal hydraulic fluid (e.g. New Holland 134) everywhere else. There are three reservoirs besides the engine: transmission, hydraulic and differential. All three have large filler plugs you can easily find on the top of each unit. The transmission and differential have level plugs on the side, about one-third of the way up from the bottom, and the hydraulic reservoir has a dipstick. The dipstick probably has different markings on each side; use the side that says "hydraulics", not "pedestal". (The pedestal side is used to check the oil level in the row crop steering pedestal.)

The original recommendation was to use 80W gear oil in the transmission and differential, but using universal hydraulic fluid is simpler, and (in my opinion) better.

There is also a steering gearbox at the bottom of the steering column. Although it originally held gear oil, it's probably been filled with corn head grease so it won't leak.

Things get more complicated if you have a row crop tractor, but it wouldn't be a 640 if you did. Row crop has two final drives plus a steering pedestal, all of which use 80W-90 gear oil.

trans fill by shifter.. level check plug on r side of trans near right heel, just above running baord.

hyds fill under left thigh/seat.. dipstick on left side inspection panel... diffy fill under right butte cheek under seat.. level check plug on back of left axle trumpet.

you can put 80w90 gear oil in trans and diff, and utf in the hyds.. or utf in all 3 utf should meet the m2c134 spec.

don't forget to service the air cleaner

Thank you very much. I checked the fluids today and they really don"t look that good. I bought some hydralic fluid today and will change them tomorrow. Again, thanks
