My temp gauge goes up pretty quickly if I work my excavator hard for about 30min. The hyd. oil seams pretty hot. Could the problem be that the hyd. pressure setting is too low and the relief valve is causing the oil to over heat? The excavator is pretty gutless when it comes to pushing dirt with the blade.

Thanks Highrpms,
I thought I had cleaned the rad good enough, but when I removed the covers and Hyd. filter, I realized the rad was pretty plugged up. thanks again, Jimayore1
