Hi guys, So last weekend we were working the 311B (8GR00134) in ambient temps in the low 90s. The hydraulic fluid temp kept creeping up towards the red and we kept having to let it idle and cool back down. Coolant temps were normal. Today we worked it in ambient temps in the high 70s. It might have hit 80 but I'm not sure. The hydraulic temps stayed normal but the coolant temps kept creeping up and we kept having to let it idle to cool back down. And then near the end of the day we started losing hydraulic power. All the slew, stick, boom, and bucket functions worked at normal speed with no load on but they had very little power when we were trying to actually do something. The tracks also had almost no power. Anyone have any ideas on how to start trying to figure out what's going on?
