Log Splitter Parts

Log Splitter Parts

Are you having issues with your log splitter performing poorly or not starting? There are several common issues that you may encounter, which can often be fixed with a little maintenance or by replacing a broken or faulty part.

Why isn't your log splitter working?

If the hydraulic cylinder isn't extending properly, it could possibly be due to a broken flexible coupler that connects the hydraulic pump to the engine. If the flexible coupler is broken or damaged, it will need to be replaced. A malfunctioning cylinder can also be caused by a problem with the hydraulic pump, which generates the necessary hydraulic pressure to move wedge. If you see any leaks on the pump, replace the seal that is broken. A leak may also be due to a seized pump. Replace the hydraulic pump if it’s seized up.

If the engine isn't starting, the first thing you'll want to check is the fuel level. After about a month of staying stagnant, the fuel in the tank can begin to oxidize and break down. When this happens, the fuel can begin to take on a jelly-like consistency that can possibly clog the carburetor. If it's not a fuel issue, make sure the spark plug is securely connected. You'll also want to check the oil and air filter to ensure smooth engine operation. If the spark plug, oil filter or air filter shows signs of wear and tear, they can be easily replaced.

What are the most common parts of a log splitter?

  1. Hydraulic cylinder: The hydraulic cylinder pushes the wedge against the log.
  2. Recoil starter: Log splitters that don't have electronic starters will have pull starters. If the rope doesn't retract or the starter doesn't engage the engine, the recoil starter may need to be replaced.
  3. Hydraulic pump: The hydraulic pump extends the hydraulic cylinder by generating hydraulic pressure. If the pump seizes up or doesn't work, it could be due to an internal pump malfunction. If that's the case, replace the hydraulic pump.
  4. Hydraulic control valve: The hydraulic fluid inside the pump and hydraulic cylinder is regulated by the control valve. It can wear down over time from routine use. If it starts to leak or the hydraulic cylinder performs poorly, replace the control valve.
  5. Carburetor: The carburetor mixes air and fuel to combustion inside the engine cylinder. Stale fuel can clog up the carburetor. If the engine doesn't run or performs poorly, the carburetor may need to be cleaned, repaired or replaced.
