  • The last Ford specification was M2C-134D. Just about every generic UTF qualifies.

  • Thanks TOH. I bought some 90 wgt for old Ford tractors at TSC. Capacity also is in question, as I drained about 4 gallons from rear end. Manual said 8 quart. I guess the level plugs on housing is the way to go. Also the drain plugs don't seem to line up for trans and hydraulic. Forward plug under trans had lots of oil drained. 6.5 for trans. I'm thinking front plug is hydraulic as lines come out the front and go to pump. Maybe someone out there has one and has the answer. Thanks guys!

  • Re: Capacity info
  • Thanks Bruce. I looked at that chart also, but what drained out was quite a bit more.
    The brakes work if it was overfilled. Time will tell when I refill.

  • Capacity is more than 8 quarts (5-speed) for the entire system -you are only reading the transmission spec. The hydraulic system uses 9 quarts so total is around 4 gallons -about what you say you drained out. I'd only refill with new, clean oil about 3 gallons at first, run it good and hot, then shut down and let settle for a half a day then recheck level and add more if needed. The oil spec is any GL1 grade so no need for anything fancy. CNH Hydraulic Oil runs $60-$70 a five gallon bucket nowadays, and many of us use the cheaper TSC brand and usually have no qualms...

  • The original Ford M-4864-A hydraulic oil specification is a mild EP (GL-4) gear oil, viscosity grade SAE 80. It was the Ford recommendation for all three sumps on a Hundred series. That is neither service category GL-1 or viscosity grade SAE 90.

    In a Hundred series hydraulic system which is separate from the transmission and drive axle you also have the option of using a conventional AW type hydraulic oil. If you go that route an ISO 46 AW hydraulic oil will work fine as long as the sump seals are toght and there is no danger of it contaminating the other sumps. IMO a good guality UTF is a better choice and can be used also be used in the other sumps so leakage is not an issue. UTF is basically a grade 80 GL-4 gear oil with some additional additives for improved hydraulic and wet brake performance. At $40 for a 5 gallon pail it is hard to beat.

  • Any UATF, SAE-80, SAE-90 wt gear oil, GL1 rated oil will be fine. Should meet the same specs as the Ford M2C-134D and later...
