Log Splitter Wont Split

[2458n]

Get a different gauge. You need one to measure pressures that you will see. If J_J says 3000 psi is max get a gauge in that range. Doubt you had a bad pump. First one maybe, but second one not likely. There is not much to a log splitter hang in there and soon you will have a working one.

Could be the seals in the cylinder letting the fuild flow past them.Check for places in your area that repairs hydraulic cylinders they should be able to test it for you.

x2.......bring the whole log splitter and they will test the cyl AND the pump with proper guages

My guess is you have two problems now.......pump unloader adjusted too high (making the engine stall) and cyl seals by-passing

But that just a WAG, best to bring it to the pros with guages before someone gets hurt

Surplus Center offers the gauge you need for less than 12.00

i have been told that i may need to make adjustments on the pump itself. i did not do any of that with the pump i had. the cylinder moves in and out nicely. it will split a small 4"-6" log. but those my 5 year old can split. when i got it it split maybe 3 rick ok then would not work most of time and every now and then would work. so i stopped using. A farmer buddy looked at it and said pump was week by taking hose that feeds the valve off and holding it in a bucket. So i replaced the pump and first time it bogged down and killed the engine. So someone mentioned adjusting the relief valve screw. I did. i can keep it from killing engine but wont split. so i put a gauge on it that goes to 13K or 14K PSI. it barely leaves the needle resting spot. The needle does a lot of jumping though.

BTW i did put new hydraulic fluid and filter on before new pump.

Do not make an adjustments to the pump as the unloader Adj. Range 400-900 PSI. It comes set to 650 psi.

You can't tell a hyd pump is weak by looking at the flow from the pump. All you will see is flow in GPM's.

If you stalled the pump, it wood appear that the log splitter was working at max, possibly with a weak engine.

To test the relief pressure, hold the lever in the extended stroke until the pressure gage reads a high pressure.

The pump is rated for 3000 psi.

If you can't get the rated pressure, then the relief valve is improperly adjusted or the cyl seals are leaking, with a remote possibility that the log splitter valve is bad.

If you can't do the test and adjusting, do as wdchyd said, by taking it to a hyd shop where they can do a flow and pressure check, and cyl integrity check.
