Today's job is a Dingo K94Y with a 27hp Yanmar 3TNV76, which was involved in a rollover / flip backwards yesterday. The client rang to inform me what had happened and what course of action was needed to check the machine over. The air box was damaged and the air filters were full of oil. This was treated as a potential hydraulic lock, so a "do not start" instruction was given. The unit was lifted by a Hiab and arrived at our shop later on Wednesday afternoon. After sitting overnight, I checked crank rotation with a 17mm socket off the front crank pulley and found that it was locked. After removing the rocker cover and three glow plugs, it turned out the rear cylinder was the only one with oil, which was over the glow plug tip. With a few jogs of the engine, we were able to expel the engine oil. After everything was cleaned and prepped, the glow plugs and rocker cover were installed back onto the engine. Now the fun starts, as we know the muffler will have a fair amount of oil inside, which will require burning off. We proceeded to get it hot, and sure enough, it belched a ton of smoke, to the point that neighbours in nearby factory units came over to see what was going on. It took around 15-20 minutes for it to clear.
