Log Splitter: Why does my log splitter's hydraulic valve leak?

Failed hydraulic valve seals around the log splitter's actuator rod can cause hydraulic fluid to leak out of the valve body. The valve will eventually fail to apply hydraulic fluid pressure to the hydraulic cylinder to extend the wedge. Replace the hydraulic control valve when you see fluid leaking out of the valve body.

Replace the log splitter hydraulic control valve

The log splitter's hydraulic control valve directs the hydraulic fluid flow to the hydraulic cylinder to extend and retract the piston and wedge. The hydraulic valve has seals around the actuator rod that can wear out and fail over time. If hydraulic fluid leaks from the valve body around the actuator rod, replace the hydraulic valve in the log splitter.
