I have scheduled two major overhauls. Can the engine be re-bored as usual, or will I run into a problem cutting through cermet layer?
Of course, to be on the safe side the engine should be re-bored! Keep in mind that the cermet layer is formed to the depth of 10 to 30 mm, whereas the cutter removes a ? mm layer of metal. But do you really need conventional major overhaul? The exceptional capacity D technology to restore the geometry of parts will allow you to get away from these labour-intensive and expensive repairs. For instance, repair of the sleeve assembly can be reduced to replacing damaged piston rings or replacing rings that have completely lost elasticity, replacing a burnt-out piston, etc. In other words, you would only need a face-lift repair, which takes only a few hours.
