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
As many Mechanics know emission controlled diesel engines need a parked regen once in a while. Most times the engine and MIL amber dash light will come on indicating a fault code to the driver. Both of these amber lights on together most times indicate an emission problem. That is true in this case… the… Continue reading MaxxForce DT Diesel Parked Regen Procedure
This was a curious question I had on these viscous engine fan drives that are very stiff and run even when the diesel engine is cold. The Horton fan clutch design is beautiful because it does not move an inch until the engine temperature reaches the proper reading.

The engine code 3055 (high pressure fuel pump related) led us to a solution in the way of a TSB (technical service bulletin). Apparently the wiring harness to the high pressure oil pump was causing a lot of headaches… Continue reading MaxxForce 7 Engine Code 3055

The SPN 2631 has appeared many times over the years and our shop knows where to look and what testing has to be carried out… Continue reading 2018 Mercedes MBE 900 Engine Code 2631

I personally have never experienced a reliable V-8 diesel engine. Maybe it’s the designing around a V-8 engine block that makes it weak in some areas. One failure that was… Continue reading 2013 MaxxForce 7 Diesel Engine Code 3055 Will Not Run
There is a substantial difference with emissions between 2007 diesel engines and pre 2007 diesel engines. Several add on components were designed to support the reduction of emissions. The older Mercedes in the video is your basic engine with turbocharger, charge air system and standard exhaust. 2007 required more emission reduction adding a diesel particulate… Continue reading Mercedes Diesel Engine Emissions Shop Talk
