What you need to know is the length of stroke , diameter of bore and the diameter of the rod of the cylinder on the splitter . . The length width and height of the tank to figure out volumes. How much that is displaced by the rod is the amount of fluid not returning to the tank . As long as that is less than the volume 80% of the tank volume you are fine .

The tank is only supposed to hold enough for expansion and side hill operation.DavidBarkey wrote: ↑Mon Apr 17, 2023 9:00 amThat is the largest tank I know of , so that is a good start .

When you use a 2-way cylinder all you are doing is moving the fluid from one side to the other. It does not drain the tank. The drive system also does not use oil volume. It just borrows what it needs with 100% of it returned to the tank.
Gotta put put this down before I forget.
224 metal oil tank size.
Length 11”, width 6.5”, depth 5.5”.
Hope to measures wood splitter cylinder this afternoon.

Ok measured the cylinder. It’s 26”. But the ram can only move 23.5”. That’s right to the wedge. So I’m guessing about 22”to 23”. I can’t remember how close it gets to the wedge. Position in the cylinder is 1.5” diameter.

There has to be enough reserve space in the tank to compensate for the volume difference that the ram itself creates in the cylinder.ssmewing wrote: ↑Tue Apr 18, 2023 12:28 pmpropane1 wrote: ↑Mon Apr 17, 2023 10:38 amI am confused.

What @Timj said... (only with more rambling...
) 
all the oil they need, there will be a difference in cylinder volume on either side of the piston - the backside of the piston has less oil because the cylinder rod is taking up space as it goes in and out - rod fully extended = more oil inside the cylinder than when it's retracted. Extra capacity in the hydraulic tank needs to be roughly equal to the volume of the rod that goes in and out - the rod is your variable...ssmewing wrote: ↑Tue Apr 18, 2023 12:28 pmpropane1 wrote: ↑Mon Apr 17, 2023 10:38 amI am confused.

Steve . The rod side of the cylinder returns less volume that the piston side due to the amount the rod displaces . The differential can be enough to empty a tank if not big enough .

And I expect to be burning wood on and off for the next few weeks, if I can’t cut wood.
