Farmtrac 545 smoking and missing.

f350ctd · Nov 12, 2023

So I have been using a neighbors Farmtrac 545 to bush hog her farm. It runs well until it reaches operating temperature then it starts having a soft miss and blowing a blue/gray smoke cloud out of the exhaust. The miss and smoke disappears when I shut the throttle when descending a hill then resumes as I apply more throttle. My thoughts are injectors or injector pump. What say you?

Always look at the simple thinks first
Fuel flow from the tank to the filters, tank screen could be restricted
Flow through the filters to the injection pump, filters could need replacing
Air filter
If these ok good I d check valve clearance before messing with the pump
I m thinking the 545 used a Bosch pump and injectors and my 555 had, this is a pretty robust fuel system that doesn t give much trouble
