Log Splitter Parts and Repair Guides

A log splitter that won't start, won't split, or leaks hydraulic fluid is telling you exactly what to fix. The engine parts — carburetor, spark plug, fuel line — are the most common culprits for starting issues. Hydraulic failures like slow splitting, loss of pressure, or oil leaks almost always trace back to the pump, cylinder seals, or control valves. Repair Clinic carries OEM and genuine replacement parts for all major log splitter brands including many model families, Earthquake, Sun Joe, and Champion.

Enter your log splitter model number to find the exact parts you need. Whether it's a small electric splitter or a commercial-grade gas-powered machine, we stock hydraulic seals, pumps, wedges, engine parts, hoses, and control parts. Same-day shipping on most orders gets your splitter back to work fast.

Log Splitter Repair FAQ

What causes a log splitter to split very slowly?

Slow or weak splitting almost always points to the hydraulic pump or a failing control valve. Low hydraulic oil level is the first thing to check — top off the reservoir and see if pressure returns. If the pump is cavitating (making a grinding noise) or the valve is stuck partially closed, the cylinder won't generate full force. A worn pump or contaminated hydraulic fluid also reduces pressure over time. Pressure relief valves that stick open will bleed pressure away before the cylinder can build force.

Why won't my log splitter's engine start?

Gas log splitters have the same starting issues as any small engine: a clogged carburetor from stale fuel (the #1 reason), a fouled spark plug, a cracked fuel line, or a broken recoil starter. If the engine cranks but won't fire, test the spark plug first — swap it for a new one and try again. If you get a spark but still no start, the carburetor needs a rebuild or replacement; ethanol in fuel clogs the needle and seat. Fuel filter blockage and a stuck choke are also common culprits.

How do I find my log splitter model number?

Model numbers are typically stamped or printed on a label mounted to the frame near the engine or on the side of the hydraulic pump assembly. For, and Earthquake splitters, the model plate is often on the engine shroud. Write down the full model number (example: 67122) and your splitter's brand name, then use Repair Clinic's model lookup to see all compatible parts. If the label is worn off, search your splitter's manual or contact the manufacturer with a photo of your machine.

What is the most common log splitter repair?

Carburetor cleaning or replacement for gas-powered machines, and hydraulic seal/pump repairs for pressure loss. Wedge pins and clevis pins also break frequently from impact and wear. For electric splitters, motor failure and power cord problems are the top repairs. Keep OEM replacement wedges, pins, spark plugs, and a fuel system cleaning kit on hand — they're inexpensive and prevent downtime when your splitter needs them.

Filter Log Splitter Parts by Your Model Number

On some log splitters, the number may also appear on the engine cover, so inspect the unit carefully and record every letter, number, and hyphen. Type it into our model number lookup and the catalog narrows to parts made for your unit, including engine, hydraulic, electrical, and structural parts. Using the complete model number filters the full Log Splitter Parts selection instead of relying on appearance or a partial match. You order with confidence knowing the fit is right.
