    When the ambient temp is in the 20's the splitter cylinder never gets real hot no matter how long it is run. However now that it is in the 80s I never run in longer than say 90 minutes as the cylinder and reservoir tank are real hot. The temp is unknown, just the palm of my hand.
    So experts, what say Ye regarding hydro oil temps. I have heard over 200 degrees is hard on the oil which is ATF.

    No idea on the exact number but I would look at the oil. If the oil looked burnt or dark I'd say it's getting to hot. :)

    Generally hydro systems are rated to a max temp of 225*-250*... Over that and the oil is cooking as well as seals.


    I know most wood splitters don't have a large enough tank and that's most of the reason.

    Tank size varies on application, but for a splitter it should be close to the output of the pump in gals.

    What does you mean by "output of the pump"? Do you mean the rated output of GPM (per minute)?

    The reservoir on the Speeco is 6.5 gallons.

    Sounds like my 90 minute rule without a cool down isn't a bad idea.

    Good question Bandit. I doubt that most splitters would get hot enough to warrant too much concern though. For sure, using the palm of your hand, it does not take temperatures that hot for you to feel it. Just think about 120 degree water and put your hand in it. That is not comfortable at all and worse, some folks have their water heaters set to 140 degrees and I'll guarantee you won't be holding your hand under a faucet at that temperature. Now consider what 200 degrees might feel like.

    As for your 90 minute break, I think that is a great idea. Truth be told, I usually don't last that long between breaks so hot oil won't be a problem for me.

    Water transfers heat better than air would so water feels way hotter than the air

    I'm not too sure of that one Clemson. I've been around a lot of folks who blew hot air and it would take a lot of water to cool them for sure.

    I put a magnetic thermometer on my hyd. tank ( 0-250 f ) that I got someplace like Amazon .
    The hottest I've seen is 140-145 . I remember reading on bob's the oil guy that upper 150s was kind of getting too warm .
    I generally take a break at 130-140 now . This winter ,I think I'll put a 20 gallon tank on the machine as a 5 gallon tank and 16 gallon pump just seems to be a bad mismatch .

    Yes. 10gpm pump... 10 gallon (or larger) tank.

    I have 9 gal of hydraulic oil in my reservoir. Use a 16 gpm pump & have an oil cooler. I can split non stop when the temperature is in the upper 90's/lower 100s & the oil stays below 130°F. The oil cooler really helps. - So does the shade!

    Oil cooler changes the game more than a little. ;)

    Problem is, many of our smaller splitters, especially th H/V type, don't have a real good place to mount one where it won't get smashed.
