My hydraulic log-splitter stopped working. No noise, no chattering, no hesitating. It seemed to have lost all pressure in a flash. Before I start replacing components on trial basis, I thought someone out there might advise me on how to approach the problem. I have no means for testing pressure. I have never had a hydraulic pump go out before. Didn't know if it would just quit pumping without displaying some symptom. The pump is driven by PTO from my tractor. I have fluid, and the pump is turning. Vernon Holt

Its probably your bypass valve (safety valve). There should be a valve in your block which dumps pressure back to the tank when the cylinder isn't calling for any. Could be on your pump outlet though. On most models it is a spring with a ball under it. Sometimes the spring breaks or gets weak or sticks open. This doesn't allow the hydraulic pressure to build up. A good way to tell is to get a pressure gauge like was suggested before. Check the pressure out of your pump, if it is ok then check the pressure out of your block with the handle forward. This will narrow your search down. Then look for a cap screw of some sort. The spring should be behind one. Check the spring and ball carefully. If you don't see any problem replace it with a new one anyway they are cheap. 9 time out of ten this will fix it.
One word of caution make sure the gauge you buy can withstand the pressure your pump puts out. A good rule of thumb is to buy a gauge which the highest number on the gauge is 2x the pressure your pump should put out. Also very careful with pressurize hydraulic fluid as if you get it injected under your skin you will have to get it surgically removed or it will cause gangrene. Good luck and post again if you need any more help.

I never cease to be amazed at the helpfullness of you who follow this forum.

Many thanks for the guidance you have given me. Soon as the weather warms somewhat I will attempt to revive my log splitter, utilizing your valuable suggestions.

Thanks again!! Vernon Holt

Before you take a bath I would advise getting a pressure gauge and that will tell you what pressure you have and where. Is the punp shaft turning? How does the valve handle feel? Does it have a logsplitter valve on it? My valve has a bypass and sometimes it sticks and lets all the pressure bpass. Good luck.

Make sure the pump is turning. You may have sheared the love joints. (rubber 3 legged drive couplings) Lossen a hose and see if you have any pressure.
