Oil cooler

Cariboo4x4 · Aug 10, 2017

Thank you for all the replys. I did not know how hot hydatulic oil can get and still work properly. I'd say tank gets hot to the touch yet not so hot you burn yourself, that is, in hot weather. I think based on the replys here I won't add an oil cooler. I've split a couple hundred cords with it. I think based on what I researched a bigger tank would help dissipate the heat. My wood splitter is home made and fellow that built it used a tank that is between 4-5 gallons.

Hi...Im not a "hydraulic guy" but my splitter has a "5 gal tank" and it works fine....but I don't run it more than 20 mins at a time. Good luck!

cooler needed? probably not, my 35 year old home made splitter has wore out a couple of engines, often was run 4 to 6 hours at a time, tank maybe 3 gallon large filter hoses valve cylinder another gallon, surface area of all components radiating heat acting as cooler ? oil temp ? often put hands on cylinder in winter as hand warmer. remember your car engine runs water temp of 195 or above so oil temp, transmission fluid probably run 250-300 without oil damage. in fact to cold allows water acids ect. to form that do damage components.

You can only touch things to about 120 degrees. Hydraulic oil does not break down until over 250 degrees. So if you can touch the tank your worrying about nothing.

Thanks for all the feedback. This splitter was my first hydraulic tool that would get really warm so was not sure if that was normal. I repacked my cylinder in 2015 and disassembled it Wednesday. The remaining o-rings and flat rubber rings were cooked hard and brittle and had lost most of their flex. The remains of the other packing seals were in filter. I'm pretty sure the last guy sold me o-rings and flat rings that were not the correct material. At the time I was in a rush to get back to splitting wood and the rings he found were from his assorted o-ring, flat ring bins. Are the flat rings called wipers? I'm hoping today this other parts guy will have located the correct packing material. Also decided not to go with oil cooler based on feedback here.

I received new packing the other day. The parts guy sent piston and end plug of cylinder to a hydraulic shop in Vancouver BC. $42 and a week later I received U-cup seal for piston. The flat rings I found out are called backing rings to prevent an o-ring from being pushed into the fine tolerance between end plug and cylinder wall. I was able to put it all together without any special tools. I had to jack piston\piston ram back into cylinder. So far splitting a few pieces of wood the splitter does not slow down and no leaks.
