    I am going through the drive system on my 1970s Hydra Mac 8c and read in the manual that the pump drive (accepts drive side of coupled shaft from engine) should have "one pint of no. 10 non-detergent oil". I haven't been able to locate this type of oil, but I spoke with Hackert Sales who specialize in older Hydra Mac machines and they told me everything in the machine gets Dexron 3 except the motor. Can anyone else verify this?

    Trans fluid is a good hydraulic oil.
    10wt oil is hard to find.lol. ATF is about 10 wt.

    Thanks for the advice. I ended up finding a quart of what the manual called for on eBay. ATF is going in the gear drive boxes and I've got some ISO 46 (20 SAE) going into the hydraulic reservoir.
