40 Series Fluid Capacities (1 Viewer)

[Hugh Heifer]

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.

I'm thinking the gas tank in 79+ 40's is 22 gallons???

I believe you're correct. In some manuals the 79+ FJ-40 fuel capacity is listed as 21.7 gallons and in others it says 22 gallons. I've pumped 21.5 gallons into my '82 after driving on empty for longer than I should.

My 1980 BJ40's tank holds 23 gallons, if you include filling it up to the top of the fueling spout with diesel.

Weird. I copied all these out of the manual

I can't find my "official" FJ40 Owners Manual, but FWIW Cool Cruisers sells replacement OEM Toyota fuel tanks and their catalog lists the fuel capacity of 1/'79-->'83 FJ40 tanks as 22.4 gallons.

40 series rear diff axle capacity

Hello All!

Just curious as the the rear axle fluid capacity of my 1974 FJ45.

I know my manual says 2.6qts - As im an aussie 2.5Lts.....

I have had some resistance from a friends dad telling me this is wrong....

He is under the impression that the fluid level in all diff are measured to the bottom of the filler plug in the housing.

If this is "correct" the rear diff axle capacity would be 3.6qts - 3.5lts....

I'm confused what to believe as he is adiment that you always fill a diff to just below the filler plug........

Could you guys please set me straight!!!!!

Cheers Jeremy.....

 

[FeralBrown]

I'd also like an answer to Jeremy's question, if anyone has it...
Might be an Aussie thing to just fill to plug level, but I've heard that a lot lately, too...

 

[1973barnfind]

okay, so what harm could be done if you fill up to the fill plug 'till 90 wt pours back out?

 

[skidplate]

I think that's how most of us do it. just leave the plug out for a few minutes and let it kinda level out.

 

[Mechnizer]

I'm a 30 year Mechanic, All the shops I have worked for and all the mechanics I have worked with have always filled diffs, Manual trans and t/c's until the the oil drains out the fill, letting it stop drooling and then capping it.

Conclusion would be that the Manufacture is required to state something to capacity.
I have never had any damage done to my rigs doing it to the drain out method.

Although if you where to over fill any unit beyond this drain method the oil will be subject to churning by the components inside and the oil would eventually be full of air homogenized !
Seals and bearings would also be subject to failure .

AFAIK engine oil capacity is 6.5 qts for the F135

 

[Brandog]

I have a 78 bj 40 and am replacing the water pump and replacing the stock radiator with a thinner aluminum one. Don't know the capacity. Anyone ? Anyone?

 

[ATLTJ]

Question from this thread. For the axles, is it standard SAE80w90 or gear oil of the same weight like: Advance Auto Parts - Down for Maintenance

I just use plain old 80/90 gear oil, I buy it in a 5 gallon pale, from a local farm supply store,with a hand pump, use it in trans, transfer and both diffs.

F-Engine oil pan capacity is either 6.56 US quarts or 5.0 US quarts, depending on which F-Engine Repair Manual page you read .

Not sure if either of these include the oil filter capacity. Use the dip stick if it’s the correct one like this v

 

[middlecalf]

I’d sure like to see other’s actual source data on F135 engine oil capacity.
