Thanks for the reply sounds like you know this motor that shaft in some of the drawings is called a silent shaft whatever that means. Not going to worry about it. its not the oil pump.they used variations of this motor in different vehicles. My main question is would you put that camshaft pip on the timing mark or advance two teeth to give you the 10 degrees advance? this motor seems to be the original. Thanks very much for the help,probably gc15 is the model. got to get this thing going before we start spring planting. Thanks
Daniel,
hate to tell you this but a Cat 2EC15 is an electric lift, no way it can have a 4G63 engine in it.
you won't get anyone to respond to this until you make a new post with the correct truck model and serial number this engine is in. And unless mitsubitshi remade that engine i never have seen one with a balance shaft in it. If this is true then they did change the engine and this truck is newer than the ones i've worked on, i mean REALLY new and a huge redesign of the engine.
