My neighbor has a 5635 SXT Series II, about 600 hours total time on the unit. The unit starts and will run fine. While using the loader the engine will suddenly bog down to the point that it will almost kill and the exhaust will turn to thick white smoke.
If you stop traveling or stop any hydraulic load the motor will slowly clear itself and then return to normal power.
There seems to be no pattern as to when this occurs.
He has replaced the engine electronic control relay ($250). The original was not sealed and when he was cleaning the electrical contacts found the water had gotten into the unit and caused serious corrosion. He has also replaced the fuel filter and topped off with fresh fuel from another supplier. He also adds Power Service fuel conditioner with every fill.
Because the problem is intermittent, we are leaning toward the theory that there is an injector sticking open.
What do you think?
