This log splitter gets about 15 hours of use every fall and spring and hadn't had any maintenance since August of 2012. We're looking at a lot of dead trees right now (Emerald Ash Borer).

I bought a 2 gallon container of ISO 46 hydraulic oil at Rural King and a NAPA filter at the dealer for about $30.00. Specs are for a Speeco Splitmaster 15 ton. You can read the manual here: http://www.speeco.com/whitepapers/LS401105LOGSPLITTER%20MANUAL2010.pdf

This has been a good splitter and never eaten any hands. It doesn't use a lot of gas and handles every kind of firewood. I also changed the spark plug ($3.00) and the engine oil (Mobil 1 10w30) which were both very burned out/dirty. The listed capacity for this engine is only 0.6 quarts. Swapping these made a noticeable difference and it starts in one pull now.

The oil had obviously sheared (?) quite a bit and had a dark tint, but there wasn't anything alarming in it.


I split the filter open (all damage to the media is mine) and didn't find anything in there either. It obviously wasn't in bypass, but I was concerned about deterioration.


I flushed the breather out and ran the cylinder unloaded a couple times; 2 gallons was about right. I didn't notice any air in the system, but I suppose there could have been.

I'm about to service my 22 ton Huskee/Speeco. Picked up some clearance Fram 1653A's for $3.79 at Tractor Supply.
My application has no bypass in the filter.

I typically split all year in my spare time. Central/Western Mass was decimated by the Asian Longhorn about 10 years ago.

Log splitter hyd fluid typically lasts forever unless it gets water contaminated. My log splitter oil is getting close to 30 years old.

It's probably built into the filter head.

How was it ascertain that this hydraulic oil is sheared ?

Watery. Thehydraulics move a little slower with the change.

That's cheap! I'm sure it works fine. There's another "serviceable part" I found behind the auto return valve. Directly opposite the handle there's a 1 oz cup stamped "Speeco" with two hex bolts that I had to drain after some problems with air in the lines (replaced 1/2" pressure hose and couldn't get the cylinder to return).

The oil inside was extra dirty and had obviously not been affected by the previous change. Air in the lines gone + the handle is much snappier and smoother. I had to fill up the cup and then squish it back on before it drained out; I'm not aware of any other way this part has oil going to it. It looks like a little ball bearing sitting inside a block with a couple rings over the cylinder.

...so that's obviously why the handle is working again.

Side note: the two number 5 hex bolts still had factory paint and came off pretty easy. After a few guesses, the total amount of fluid not displaced was something like a 1/2 oz. It will just bubble out until it reaches the "correct" fill otherwise (still don't want it doing that when someone else is running it).
