Hey everyone, brand new here. Sorry if I miss something but I will address any mistakes. We have a 2013 7FBEU20, Serial 21554, 3 lever (not the mini 4 lever variant) 36v.
When lifting a load the hydraulic pump (I'm 90% certain it is the pump) starts screeching loudly at about 3ft-4ft and the lift rate slows down. I pulled the truck from operation and its in our maintenance bay. The fluid level is full, I do not see any leaks currently. It is a 'new to us' truck. I have yet to do anything invasive, I was unsuccesful at getting into the programming menu to see what the pump RPM is set to (something I discovered was possible from sifting through this forum. ANY help is greatly appreciated and I will provide any missing information. Thank you.
