Hi All
I am looking for some help on a log splitter issue I have. I tried searching, but could not find someone who described a similar issue of inconsistent performance.
I have a 18 ton log splitter (4" bore @ 3000psi) with a 2 stage hydraulic pump driven by a 3-hp 1800rpm electric motor. Everything is basically brand new (less than 2 hours on it). I installed a pressure gauge on the outlet side of the pump and brand new oil. The splitter serves double duty as a press as well by replacing the wedge.
My issue is when I first start splitting, I can dead head and build 3000psi. But after using it for a while (maybe 15 minutes) I notice it getting weaker and I will check it and it will only be able to build like 2000psi and it seems like it maybe taking a bit longer to build the pressure. Nothing seems like it is getting very hot. If it is 40F out, pump and reservoir and control valve maybe feel like 60F?
If I let the splitter sit for about an hour, it will return to the 3000psi pressure.
I suspect aeration, but my reservoir is full and the only thing that seems to be leaking is a very slight weep from the cylinder seal.
