![]() These can clog the filters in your engine, and prevent it from running properly. Particles of sand, dust, and rust may contaminate your diesel fuel. This rust can in turn clog your fuel filter. If your diesel gets contaminated with water, it can cause the iron and steel components to rust. Water is very damaging to your diesel engine. Some of the most common types of contamination of diesel fuel are: Fuel ContaminationĪnother potential cause of a diesel tractor stalling is that your fuel has been contaminated ( source). This causes the filter to block air intake instead of clearing it. ![]() There are other air filters in the engine, and surprisingly often these are installed backward. If the air filters are clogged, like in the fuel cap, the engine will not be able to pressurize, and again the tractor will stall. If the fuel filter is clogged, the fuel will not flow through it and cause the engine to lose power. Filters affect all three of these mechanisms. If so, the filter will need to be replaced.Īir, pressure, and fuel are the crucial components of a diesel engine. One way to check this is to remove the fuel filter (bypassing it) and see if the tractor runs. Often, the fuel filter can get clogged on the intake side of the filter. Assuming you have enough diesel fuel in the tank, check the engine hoses for blockages. Determine if You Have a Fuel Delivery IssueĪnother common reason for diesel tractors to stall is a fuel delivery issue. I generally recommend removing the cap and giving the vent a good cleaning then seeing if that solves the issue. Either try cleaning the cap, then putting it back, or order a new one.īut I don’t like that troubleshooting approach because you can introduce impurities into the tank if it isn’t capped. If the tractor runs without issue, then the problem is the fuel cap. To check if this is the cause of your problem, it’s often recommended that you remove the fuel cap, start the engine, then run it for an hour or so. If the vent is clogged, the engine won’t be able to properly pressurize, and the engine will be stifled and die ( source). The most common cause of a diesel tractor stalling is a clogged or damaged fuel cap vent.ĭiesel fuel caps have vents to prevent a vacuum effect. ![]() Make Sure The Fuel Cap Vent Is Not Clogged Let’s break down each of these points of failure and see if we can identify what’s causing the issue and get you back to work.
