I have a 2012 Skytrak 8042. When I'm running the hydraulics, the engine is bogging down and dying. The local JLG mechanic isn't convinced it's the hydraulic pump. Any thoughts?
This is exactly what mine is doing when starting back up after it stalls. Mine is a 2013 skytrak 8042. Machine initially wants to stall again initially, but will operate and drive as long as you are raising or lowering the boom at the same time. The first indication of this problem we had was the machine wanting to stall when tilting the forks unless we were using the throttle as you use that function. Now this. I feel this is something with the pump or something related to the hydraulic system. However, I’ve had a mechanic look at it that sent a Cummins technician out who said I need to bring it to them for a new engine. This doesn’t seem correct to me that it would run better under a load if it were the engine. Any advice or where to start to diagnose this? Cummins wanted me to haul the machine to them for an engine they quoted me $34,000 forFor it to start back up, I've got to hold the lever for a hydraulic function and hold the pedal down. It will then blow a lot of black smoke and then be fine. Sometimes the engine will die when retracting the boom, tilting the forks, or even just turning the wheels.
