Hi Jimmy, I would check the oil temperature after the hydraulics start to fail to confirm. A typical heavy use hydraulic system would have a oil capictiy of 50gals to keep temperature down but as posters suggested a after-cooler will also work. You might also consider adding a check valve before the cylinder in-put hose and if the cylinder leaks down then the cylinder seals are getting pretty worn out. Or make a hydraulic pressure tester with two pressure in-puts, thus the pressure in-put of #1 would decrease while the pressure in-put #2 would increase indicating the cylinder seals are leaking and how fast there leaking.

The cost of the check valve will be more/about the cost of new seals. My 2.5" bores cost about $15 for a complete seal kit and my 3.5" bores cost $45 a kit plus I have to make a few spacers as there nolonger available. I used a engine cylinder hone to scuff the cylinder bores.

A pressure tester is about $50 for a one pressure system and about $75 for a two in-put tester from Northeren Tools "parts".
