I am talking about just the governor part of the injection pump, it is basically the back section of it. I have checked high rpm with a reliable laser rpm meter and get consistent 2120 high rpm and 720 low rpm at crank pulley, manual calls for 2080 no load and 2005 during operation of boom and stick. I called a fuel shop and they will only do a complete overhaul for the entire pump for around $2000 even if I have just a broken spring or something, so obviously I am not taking it there.
I feel like the engine is not adjusting rpm when a load is put on the hydraulic system, if it is supposed to, it will just die slowly.
I have been going through the procedures for checking and adjusting the hydraulic system first, what else would I check on the fuel system if all the lines are new, new filters, transfer pump is rebuilt and delivers plenty of pressure to the injection pump? Turbo seems fine but I don’t really know how to check it. There is no play or slop in it.
