My machine has started acting up this week , the first 10 minutes or so of the morning the machine will run fine functioning properly but when it gets heated up it is as if the engine is bogging down, it has black smoke pouring out of the exhaust while digging and dumping out the bucket, if you arm out and hold it the machine will kill itself and then crank right back up. I replaced the turbo today thinking the black smoke was a lack of boost/air and the turbo on it was caked in oil on the intake side. No change, about two years ago H&E replaced what the mechanic said was a proportional valve underneath the hydraulic pump. The numbers written on it are 010774. I unplugged on of the wires on this valve and it got significantly worse could barely lift up the boom. Could it be going out again? It was replaced about 1.5 years ago, thing was 700$, any way to test it ? https://www.youtube.com/shorts/-UuJVi_-81E (Short video of machine running)
Thanks for any advise.
