Changing Hydraulic Oil

[RCLogger]

Here is another way to get your oil out of the tank and filter fast without having to use a syringe. Just take the screw out of the filter and add a nipple with a hose attached, put the hose in a cup. Turn on pump and within a few seconds they are empty...

I figured I'd share my experience here!

I'm glad I changed the oil! Mostly for peace of mind to know when it was done last and when it has to be done again. Didn't take much time at all. Here is a comparison btwn the old and new oil!!!:





The syringe I picked up worked great to fill the reservoir, its made by Chefmate, its a "flavor injector," got it for $3 at my local target store. Highly recommended for filling the system! I had to use a smaller syringe to draw the fluid out.

How often should I change the oil in the machine?

Guys just a little suggestion. If the oil comes out of your equipment looking that bad your looking for big trouble down the road.
That oil is the life blood of any hydraulic system big or small. The dark coloring is metal fillings from your pump eating it's self up.
Never, never leave it till it's that color. Cleanliness is of the utmost importance!.
You should change it at least once a year and maybe more if there's allot of dust in the air.
Even pouring oil strait from any container is bad. It should all ways be filtered on the way into the tank. Had to replace a pump once, because there was plastic that somehow made it into a brand new container.
The oil that came out of Gregs machine is the way you want to see it in the container, still looking pretty clear, That way your pump and cylinders are going to be happy. Any other way and the grit is tearing up your o-rings and the pump gears even if you have a filter.

That is a story and a half Rob. It took me two hours to get the oil in that hyd machine to look that clean, and half a litre of oil. I unhooked all the cylinders and manually sucked oil in and out of them to get them clean. Changing the oil each time I cycled them.
I thought I better get it done before you seen how dirty the oil was.

I'm kinda new here but seems like this ought to be a sticky.

I learned something today !
Where I took the bolt out from the filter, it is a place to hook up a line to a pressure gauge to see how many bar you are operating the pump at...
