- We retrofit a new Hydraulic oil return filter to a 3 point hitch wood splitter that has been powered with a Honda GX160 motor. The previous owner did not bother to install a filter. The whole project took about 40 minutes to do and all in cost was around 75 dollars.
Hello Friend
Are you sure this is no place for a hole for a 1/8" NPT hole to be drilled? Are you referring to replacing your filter head?
you could just put a Tee in between the DCV and the filter head it will still give you a back pressure reading indicating filter condition in respect to dirt loading. I bought the filter head years ago and it's what I had lying around. Don't get hung up on flow rates through the filter or housing, you have plenty of capacity. Dirt is more of the enemy. 40 microns is not enough and 6 is probably silly. Use fiberglass media (Synthetic) as it will not react with moisture as Cellulose media does. you pay a bit more but you get the value in performance. If there were cheap filters on the unit before, better buy 2 filters. The first will load rather quickly. Mann + Hummel Gruppe of Germany are the current owners of WIX so although the filters are technically WIX that fact may not be present on the box. I trust NAPA filters but my go too is the Platinum Series. On a side note the FRAM Ultra Synthetic is a very good filter as compared to the incredibly cheap Orange ones. Startups will show high back pressure until the viscosity changes with temp, so don't be alarmed
Love this video. This guy reminds me a bit of my dad. Technical guys who know their stuff don't care if their fly is open all day. Thank you, great informative video!
Thanks man, was my fly 🪰 open?
@@JimsNBHomestead it was open or ripped, but no matter, I now know how to filter the oil on my newly purchased, sat in the trees for 30 years, log splitter! Thanks! Heck I might even try to do a TH-cam video on bringing it back to life! Thanks for the inspiration!

Say what?
Do it man
Great Advice!!!
Thanks for the amazing feedback
I just read your explaination on why not put the filter on the uptake and it makes sense. I did it on the uptake and broke the part that connects the pump to the unit and had to replace it. Lucky that is all that broke.
Well you got lucky, thanks for being a part of the channel
@@JimsNBHomestead I did not mention that I did it on a 22ton Forest King, Maybe the connector was different and maybe that is why I did not do more damage. I had issues with the pull start as in my opinion they planned on it stopping working at some point. I "Tim Allened" and fixed it. lol I would explain, but that is not what your video is about.
You got it fixed, that's what counts
Question for all the experts here: Can a filter on the return line cause the cyl. wiper seal to leak?
I hope you put a lift table, too, at some point, best thing I ever did for mine.
We plan on a total rebuild soon, so maybe
Filters are awesomeness
yes they are
Very good
Thanks Terry
thanks Terry
Having a filter is very smart and draining off bottom of tank when cold is also very smart and important for proper care 😊😊
Change oil on engine every 25 or less hours will pay off also
Yes it will save money and repair costs
Agreed 👍 and thanks for your kind words
Changing filter pays off? How?
Nice video, Jim.Reminds me to change the filter on my splitter.What wood do you most commonly split and burn in New Brunswick?
We burn mostly birch out here. I do have hemlock to burn this year as well
hello, good and very good... sorry, how many cc is the pump, if you use a gx160 engine
13 CC per revolution turning 3200 RPM
Yes it is 13 CC per revoultion
I did not see a pressure relief valve anywhere in the system.. you might want to think about adding one before you burst a hose or something
Ahhh my dear friend, thanks for the heads up. Unfortunately you are incorrect in your assumption of there being no pressure relief valve. You see it is integrated into the control valve and functions in both directions. This setup is used in most types of hydraulic systems on mobile equipment. I am a certified mobile hydraulics technician and have many years of experience working with these systems. Thanks for watching and commenting
@@JimsNBHomestead in your video, you say you did not see a pressure relief in the directional control valve. Like you, I did not see it either. I looked up the valve and found where it was. A little different than most valves. As far as a 2-stage pump goes. They don't kick in to any gear. They have a high volume low pressure side and a low volume high pressure side . The high pressure side is pumping into the system all the time. When system pressure reaches 500/600 PSI the unloading valve in the pump opens. Dumping the high volume side back to the inlet side of the pump. The low volume high pressure side continues to build pressure .
@@Georgemerglo kicks into gear is basically a slang term not be taken literally, and technically this is a gear pump so it does kick into high pressure gear.
At the time of making the video I did mistaken the unloading valve for the relief valve. What I meant by kicking into gear was the high volume section unloading and the low volume high pressure side of the pump taking over the chore of splitting the log at the cost of cylinder velocity. We only have 5hp to do the work and speed and force are the variables. One is at the cost of the other. These are simple hydraulic systems and relatively low powered. This splitter was actually a 3 point hitch attachment for a tractor. It works decent but the lack of a filter was concerning thus the whole point of the video. I'm curious did you do a log splitter video?
Is the pressure relief valve integrated into the filter in the return line?
The hydraulic take why big anuf my old vinggard logspliter it hole lot bigger then yours I run my 13 a day no issues my take 2gal it stays very cool I been work on small engine over 39 years experience school 4 years small engine diesel engine
I have been a hydraulics specialist for many decades but hey I appreciate your input
Thanks for the video, does it matter whether you put the filter on the return line vs the supply line to the pump?
I understand your question totally, but I will give the three scenarios for filtration. 1. Suction filtration (to the pump) is not ideal due to the fact that hydraulic pumps do not like having to suck oil very much. In fact this will lead to a problem called cavitation which is the kiss of death to the pump, and the pump prefers to be flooded . 2. Pressure filtration (from the pump) is doable and in some complex systems recommendable. However very expensive filter assembly and very expensive filter elements. Pressure filtration is at full system pressure which in this case is about 2500-3000psi.
3. Return line filtration (back to tank) is usually the best option. It is the least expensive but in my mind the most effective. the dirt is captured before it gets back to the tank. It is the cheapest option, and its usually is the most versatile in adaptation. Return line filters operate with a pressure of around 10-25 PSI. They can be equipped with a by-pass valve for extremely cold start ups or when the get plugged with dirt (get a gauge ) and require changing. I hope this helps, and as you can see I went with Return Line Filtration. Cheers
@@JimsNBHomestead thanks for the explanation, that all makes sense!
I'm glad you picked up on it
