Today however we are talking about the fact that this engine comes with a rear gear train and some of the pros and cons of having an engine design like this. I also explain the origins of the 3L duramax and most likely why this 3L duramax engine comes with a rear gear train. most american engine are front gear train engines for better servicibility and access to this critical engine components but in the europe where this engine was designed the vast majority of there trucks are cab overs meaning the cab tilt up and the rear of the engine is exposed leaving tons of room for servicibility. so it makes it challenging for this engine having a rear gear train design in america where the cab cannot be lifted and it makes some engine repairs very difficult. 00:00 - Intro 01:27 - What is a Rear Gear Train? 01:47 - 3L Duramax European Origins 03:40 - European Expedition 07:09 - Pros of Rear Gear Train 10:11 - Cons of Rear Gear Train
