Often asked: What Motors Fit My Log Splitter?

What size motor do I need for my log splitter?

If you are serious about making your own backyard log splitter, then you want to have, at a minimum, the following components to provide the right amount of force and power for basic splitting of averaged sized, seasoned logs: A 5 Horsepower engine. A two-stage hydraulic pump rated at a max of 3 gpm at 2,500 psi.

Is 5 hp enough for a log splitter?

Support Guy: ” 5hp isn’t enough. You need at least 6.5hp*.”

How do you size a wood splitter pump?

So, a 4 X 24 would break down as follows: 3.14 X 22 (Radius = Bore divided by 2) X 24 (Stroke) = 301.44 In3. 301 In3 = 1.3 Gallons.

  1. 11 GPM pump = ~7.1 seconds (1.3 g / 11 gpm X 60 seconds)
  2. 13 GPM pump = ~6.0 seconds (1.3 g / 13 gpm X 60 seconds)
  3. 16 GPM pump = ~4.9 seconds (1.3 g / 16 gpm X 60 seconds)

How do I know what tonnage my log splitter is?

With a little simple geometry you can calculate a cylinder’s force in pounds or tons. The pound force is the product of the fluid pressure in psi multiplied by the cross-sectional area of the piston. To get the hydraulic cylinder tonnage, divide the pound force by 2,000.

How can I speed up my log splitter?

Only way to speed up a splitter is to move more oil. Either get a bigger pump or speed up the existing pump.

How do you replace a coupler on a log splitter?


  1. Disconnect the spark plug wire. Disconnect the spark wire so there’s no chance that the log splitter engine could accidentally start.
  2. Remove the hydraulic pump.
  3. Remove the flexible pump coupler.
  4. Install the new flexible pump coupler.
  5. Reconnect the spark plug wire.
  6. Test the hydraulic pump operation.

How do I know what size hydraulic pump I need?

Use this equation to help figure out what electric motor horsepower (HP) is required to drive a hydraulic pump. SImply take the gallons per minute (GPM) multiplied by the pump pressure PSI then divide that number by the result of 1,714 times efficiency (we used 85% effiencey in this case).

How much HP does a hydraulic pump need?

1 HP is required for each 1 GPM at 1500 PSI or any multiple of 1500 such as 3 GPM at 500 PSI, 2 GPM at 750 PSI, 1/2 GPM at 3000 PSI, etc. Another handy rule-of-thumb is that it takes about 5% of the pump maximum rated HP to drive the pump when unloaded and pressure is very low.

How does a hydraulic wood splitter work?

Most log splitters use a hydraulic cylinder (like these) to push a cut piece of log into a sharpened wedge, which splits it. The cylinder is driven by hydraulic oil, under pressure, produced by a hydraulic pump. The oil from the pump runs to a hydraulic valve, which provides control over the movement of the cylinder.

Is a log splitter worth it?

There is absolutely no point in buying one if you only intend to use it once. Go out and rent one for the day. But if you and your family rely on firewood to heat the home, or if you simply love campfires more than most. Sure thing, buy a log splitter.

Is a 22 ton log splitter enough?

Depends what you’re going to be splitting. Most of my wood is large oak, and a lot of it is crotches. I need 35 tons. If I were splitting mostly straight grained stuff, I’m sure 22 tons would do the job.

Are electric log splitters worth it?

In the 21st century, technology makes splitting wood easy and fast. Yes, axes are great for splitting a few logs once-in-a-while but if you have a lot of logs to split on a regular basis then an electric wood splitter is indispensable for homeowners.
