The Fordson Tractor Pages Forum

Can anyone tell me what the modern day replacement oil and fuel filter elements are for my FMD are please. Although my tractor is a 1957 model, the engine is a 1956.

The oil filter is 135mm long, 70mm ext dia and 20mm int dia

The fuel filter is 80mm long, 70mm ext dia and 20mm int dia

A Fram, Coopers or Mann filter numbers would help my local supplier to cross ref

Thanks

Oh and what grade of engine oil would anyone recommend? The grades listed at the top of this forum are no longer available.

Can't give you the filter refs but I can tell you that most of the oil grades are still available, Old Twenty Parts, and Morrises of Shrewsbury will send them to you, Castrol still does Castrolite, XL and XXL, Shell does TOU and there are many others.

I use Freedom 15/40 engine oil in Nuffy and Halfords Old Engine oil in the petrol tractors.

Thanks Brian, I’ve been thinking about using an agricultural 15/40w myself.

Do you use it all the way through your Nuffy? Gearbox, Backend?

Ford has recommended for the rear axle one time 80W-90 gear oil and also SAE 30 motor oil. I feel that the gears like more the 80W-90 oil, but the hydraulics SAE 30 oil, especially in cold climate.

As Fordson does not have hypoid reduction in rear axle even engine oil could be used, despite the rear axle (and gearbox) are more noisy. Agricultural is better for the gears than motor oil, as it includes also GL4 classification.

I use allways 80W-90 in gearbox and even in the rear axle as the tractor is in varm garage.

I use it in everything.

Ford have recommended such oils since 1959 for all tractors back to 1952 and in the dealership this was what we used. Nuffields changed it in the 1960's too. They were all looking for an oil that would run in everything, giving reduced effort in gear shifting and reduced drag through the transmissions. Also the user would only have to stock one oil for all his needs.

It was also thought that the higher viscosity oils would not be as fluid and would have less lubricating effect as transmission speeds increased.

The main problem with using some "Universal" oils in the engine, is they are designed to be used in tractors with "wet" disc brakes and include "anti squark" additives. These tend to plate the cylinder liners and cause glazing, especially in engines that are not worked hard at their optimum temperatures.

This is not to say they are bad oils, the problem has been known for many years and we were suffering from it in the 1960's. Mercedes and Perkins would not allow its use in their engines if they were still under warranty even back then.

That is why straight car engine oils are sometimes OK to use. I use Castrol GTX in all my cars, petrol or diesel. It is certainly a good oil as far as I am concerned having put 400,000 on a Diesel Sierra engine, 200,000 on another, 300,000 + on a Mondeo Diesel.

I am told the specification exceeds most of the requirements for the older engine and keeps up with the modern ones too.

I'm not trying to tell what is correct. Only some aspects regarding the oils.

The increased noise from gearbox and rear axle with motor oils does not make me happy. I like more to hv gear oil in gearbox.

To hv one oil in rear axle, gearbox and motor is the dream of oil companies. It is not possible without compromises. The glazing of cylinders is one of the problems. The viscosity of gear oils is not comparable to motor oil numbers. Gear oil SAE 75 is between SAE 10 and 15 motor oil. SAE 80 gear oil is abt. the same viscosity as SAE 30 motor oil. Difference in numbering exists only to avoid mixing of oils of different type.

I use the New Holland oil for trans. and rear end, it is a 20/30 wt. Because of leak from trans. to rear end, which a lot of Fordsons have, I have to use same oil. Use Rotella 30 wt. for engine. I'm no expert at anything but maybe oil is different here but the 80/90 wt. gear oil I use in other equipment is a lot thicker than the 30 wt. oil.

Yes I understand where you're coming from Brian, I use a 20/50w through out my Fergie TED-20. Not sure if I want to put it in the gearbox or back end until I've had a look inside and cleaned it out.

Gear oil SAE 90 corresponds in viscosity abt. SAE 45 motor oil index. SAE 80W-90 is as cold SAE 80 as hot SAE 90, despite it is much thinner as hot than cold SAE 80 gear oil (or SAE 30 motor oil).

hI all , iwould just like to clear something up referrig to [motor oil ]as used loosely, do you mean diesel or a petrol whe usenig the term motor oil, or does it not matter if it is diesel oil or petrol as long as it is motor oil, ithink there could be some confusion with the term motor Gerry

Hi Gerry, I’m referring to Diesel motor oil in this case and this thread, although when I referred to my Ferguson then that was a Petrol motor oil. Does that make sense to you?
