Hydro trans gear oil.

I've been on the search in this forum for what to use in my 1947 Ford 2N hyd trans and gear system. Almost everything I have seen here isn't available to me. I'm wondering if someone who's got knowledge on this could check this out

Is this suitable for my application?

thanks there's a lot of good info there

Yes,
Lots of good advice in Bruce's tips.
As for the oil to use, New Holland
recommends using a UTF that meets Ford 134D
specs.
Lots of guys on the Ford board use it in
their big 60, 90, 130+ horsepower tractors
that have 16K hours on them with good
results.
Compared to straight gear oil like 80W90 it
will leak more because it is thinner.
But if you are the type who thinks good
tractor maintenance includes fixing leaks
that won't be a problem. 134D will also
perform better in winter conditions if you
live in cold country.

What about the 303 Tractor/Hydraulic Oil, it seems to be the least expensive, ( Around $20.00 for 5 gal) are there any reasons not to run this in a 2,9, or 8N Tractor?

Yes - you can use just about any premium Universal Tractor Transmission Fluid (UTTF). They are all generic equivalents for the Ford M2C-134D product originally recommended by Ford and now CNH. The Phillips HG is just one of literally dozens to choose from. I will bet you can find a whole lot more in your area if you know what you are looking for.

If you look at the Philips data sheet you will see it is available in two different viscosity grades. The heavier grade has a viscosity of 9.4 cSt @100C which is the specification for Ford M2C-134D. That is generally suitable for year round use in an N-series tractor. The "low-viscosity" grade has a viscosity of 7.4cSt@100C and is intended for use in extreme cold - e.g. temperatures below -20F. Both grades have extremely high viscosity indexes which means their viscosity changes relatively slowly with temperature making them good all season products.

One word of caution - avoid anything with "303" on the label. These are low-grade products with minimal additive packages and a very low viscosity index. They are not suited for use in temperatures below freezing and not a lot better when the temperatures are above freezing.

See my response to the original poster.

Thank you Rnfarms, I will steer clear of the 303 and use the premium grade UTF, with the higher viscosity.

It's not the viscosity that is the issue. It is the abysmal viscosity index and additive package (or lack thereof) of the 303. As a point of reference monograde gear lube has a viscosity index of roughly 95 which is pretty mediocre in today's world. The 303 product data sheets are pretty fuzzy on VI - they just hand wave a number of "60 minimum". Probably because the actual control of what is in the pail is so variable there is no reliable number. The VI of a premium UTF is 130 plus. The Phillips low-vis UTF (e.g. John Deere J20D) is the same base viscosity as the 303 (7.6 cSt @100C) but has a VI of 190 making it a VASTLY better all season oil/cold weather oil.

Just FYI - the 303 number comes from an old John Deere specifcation (303) that JD abandoned LONG ago and no longer recommends for use in anything new or old.
