Log Splitter: Hydraulic pump leaks
When you see your log splitter leaking hydraulic fluid from the pump, failed pump seals are likely allowing hydraulic fluid to leak out from gaps around the pump's drive shaft. The pump will eventually fail to build up enough hydraulic pressure to move the piston and wedge because hydraulic fluid leaks past the seals.
Replace the hydraulic pump when you see the log splitter leaking hydraulic fluid from pump drive shaft seals.
Replace the log splitter hydraulic pump
The log splitter's hydraulic pump generates the hydraulic pressure to extend the hydraulic cylinder and wedge. Over time, the hydraulic pump starting to leak fluid through worn seals when pumping hydraulic fluid. The pump eventually fails to build up enough hydraulic pressure to move the piston and wedge. If the pump seals are worn out, replace the hydraulic pump assembly. The hydraulic pump can also seize up due to an internal pump failure. If the hydraulic pump in the log splitter seizes up, replace the pump.
The flexible nylon pump coupler deteriorates over time. Replace the flexible pump coupler if it begins to vibrate or rattles, which are early indications that it’s failing.
The carburetor mixes air and gas before the fuel mix goes to the engine. If the engine won't start and the spark plug is getting spark, the carburetor is likely the problem.
The recoil starter spins the engine on the log splitter when you pull the starter rope, and the rope retracts when released. If the recoil starter assembly is broken, follow the steps in this repair guide to replace it.
