mitsubishi 4G63 engine timing

I have a 4g63 single overhead cam in a catcg15 lift truck. removed the head for a valve job and now have to time the cam to the flywheel. i have two questions 1 this motor has a balance shaft or a silent shaft as its called, one website says you need to remove a plug on the side of engine block insert a screwdriver to make sure the oil pump is in the proper location.first time ive ran into this and 2 on the cam timing marks it says to line the pip on cam pulley two teeth before the mark on the block which could make sense becauce it fires 10 degrees btdc. thanks in advance

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.
