I posted a similar video like this one a while back with the same scenario. I thought it was important to show again the importance of what to check when a diesel fails to run. The saying everything happens in threes is very true within our fleet. I’ve seen it happen many times because the… Continue reading MaxxForce DT Diesel Engine No Run Problem
I will not hold back in saying of all the tools Navistar provides their software is excellent. The NED (navistar engine diagnostics) works very well to maintain and troubleshoot all of the engine models. When an engine code pops up out of the blue you want to get on it and see what is going… Continue reading MaxxForce DT Regen Using NED Software
With the right fittings from your local hardware store you can test the injection high pressure manifold that can cause diesel performance problems on a MaxxForce DT when it develops an oil leak. As the video shows there is a substantial leak on this manifold. So we could have just removed the manifold and replaced… Continue reading MaxxForce DT Testing High Pressure Manifold
This is a typical procedure for doing a regen on an International diesel engine. In this video it’s the MaxxForce DT. This engine model has been floating around as the top subject for my articles here on the Hub. I’ll tell you something about these diesel engines. They have issues so I write about them… Continue reading Parked Regen Using Navistar Software
Installing the cylinder head on an International MaxxForce DT diesel engine is intimidating for the novice but as I always say follow the instructions in the manual to the letter and you will never go wrong. The video specifically shows how to torque down the head bolts after the threads are coated with a light… Continue reading MaxxForce DT Cylinder Head Installation
Once the cylinder liners were secured and measured for protrusion the new pistons were then installed with new bearings and rings. This is where care (as always) needs to be taken especially when installing the pistons. The rings need to be turned to the correct position 120 degrees apart from each other so the open… Continue reading MaxxForce DT Engine Rebuild Progress Report
Our MaxxForce DT engine in-frame is rolling along with new main bearings being replaced (rolled in). The Mechanic has to roll in the bearings on the top half since the crankshaft is not being removed. The engine rebuild manual is as important as a bible in church. You’re going to be lost without it. Guessing… Continue reading MaxxForce DT In-Frame Update
Did you watch this video? Look at all of that smoke coming out of the oil fill tube. That is severe blowby caused by compression escaping by the piston rings and getting into the crankcase creating pressure. This International MaxxForce DT is a 2011 diesel engine that needs some rebuilding to get it back to… Continue reading International MaxxForce DT Diesel Engine Worn Out Analysis
The video tells the story on the running condition of this MaxxForce DT diesel engine. International designed these engines to run on high pressure oil to hydraulically actuate each injector electronically by the on board computer which is separate from the fuel system which runs at 75 psi. This engine sounds like it’s running on… Continue reading International MaxxForce DT Diesel Engine Miss Repair
This step involves replacing and torquing down the main bearings on a DT MaxxForce diesel engine. The main reason for replacing the bearings is to bring the crankshaft end play back to specs and replace the washed out original bearings. Some of them showed discoloration so we didn’t want to take a chance. The coolant… Continue reading Main Bearings DT Diesel Engine in a School Bus
