I have done a bunch of searching and discovered some of the other series had a thread dedicated to their fluid capacities as well as types of reccomended fluids for their vehicles. I may be mistaken but did not see that for the 40. So here is what I comiled from one of the "more useful" commercially available manuals:
Engine Oil: 8.5 qts Weight specific to environment
Axle Lube: 2.6 qts SAE 90 Weight
Steering Gear: 0.6 qts SAE 90 Weight
Power Steering: Dexron II (or newer) Automatic Transmission Fluid
Coolant: F Engine 17.5 qts
2F Engine 19 qts
1978 19.9 qts
1979 - 1982 16.9 qts
Fuel: 18.5 Gallons (pre 09/73)
16.4 Gallons (09/73-12/78)
22.0 Gallons 01/79 and later
Clutch: Dot 3 or SAE J1703
Brakes: Dot 3 or SAE J1703
Transmission: All SAE 90 Weight
Three Speed: 3.6 Pints
Four Speed: 6.6 Pints
Transfer Case: 3.6 Pints
Transfer Casew/ PTO: 4.4 Pints
PTO Winch: 1.2 Pints
As with some of my other posts, these are publsihed and not my own idea so don't punish the messenger if you feel they are wrong. I also did not recommend a weight on the engine oil (for obvious reasons) or a type of coolant (I just know Dexcool should be avoided). Any input on coolant or oils for a specific climate or set up could be
useful here.
I also beg that any of the other threads on capacities and oil/fluid debates get linked to this for FAQ. I think we would all find those useful in one place.
