How Much Hyrdaulic Fluid to Add for Splitter???

HarleyBob · Jan 25, 2006

I added a hydraulic log splitter to my Kubota L3010. The splitter attaches to rear hydraulics and has a pair of 54" hoses and
the ram cylinder is 4" diameter. I have been running the splitter for a few hours and have added about 1.5 gallons of fluid to the system and I am still a bit low. I am not leaking, as far as I can tell. What is normal for extra fluid for such an implement. I want to make sure I am not leaking somewhere I have not detected yet.

Well if it is a 24" stroke cylinder it has an internal volume of around 301 cubic inches. That volume will hold a little more than 1.3 gallons by itself. That is with the ram fully extended. Fully retracted will hold less due to the fluid displaced by the rod. The two hoses should account for about another .1-.2 gallons depending on their Inside Diameter.

Ronmar, Then I should be in range as I also added a hydraulic
toplink with hoses (which I failed to mention). That should have drawn about .5 gallons. It sounds like anywhere up to 2 gallons
for both cylinders and hoses should be expected.

As an example, a 2" X 10" cylinder will take about .3 gallons of fluid when fully extended. I would say 2 gallons sounds about right for both your cylinders and their hoses.
