Anybody a Hydraulics Expert???

[Docwheelhorse 2,561]

Hello All---I put my new log splitter together about a month ago and filled it with nearly 9 gallons of John Deere Hygard Hytran oil (suppose to be the best hydraulic oil going---plus my friend owns the shop and I got a deal ). Anyways---I ran the stuffing out of the unit today (5 cords) and was very pleased with its performance---I noticed the tank getting warm and decided to stick the thermometer I borrowed from Sparky in the tank---well it read 135 and stood there even after 2+ hours of constant splitting. I think that temp is fine but I just wondered in an "ideal" situation is that too cold, too hot or just right from a performance/longevity standpoint?

Thanks!!!!!

Tony

We use mixers at work with large hydraulic pumps and motors.

The two large mixers have 125 hp motors on them. We do regular PM checks on them. Depending on the product in the mixer the temps in the hydraulic tank is between 120-140 degrees.

Thanks Duvall---on another note, how often should I change the hydraulic oil (how many hours of use??) There is a filter and like I said---it holds 9 gallons....

Appreciate the response

Ur oil temp sounds about right after splitting all that wood. Ur oil

geets hot because of goingthrough the pump under pressure. As

of how long on a oil change , about every four years unless you

get moisture in the tank or in the oil. That causes major pitting of

the pump piston causing it to not build pressure. There u have it
