Top dead center on an engine is defined as when the piston is farthest from the crankshaft. Bottom dead center is when the piston is closest to the crankshaft on the engine.
You can perform a valve adjustment, on your 3412 Caterpillar diesel engine, by rolling the engine to the number one position. Tighten the valve adjustment screw. You will need to do this for each piston position.
You have to set your camshaft at a position of firing at number piston ,that is if the camshaft gear does not have a visible timing marks and in relationship with the crankshaft position it has to be position number one piston at TDC
Top dead center. It is when a piston is at its highest position.
the rotor should be pointing towards the number one plug position on the distributor cap, and the engine should be on compression stroke. If its not the motor will be 180 degrees out
It's the front (front of the engine is front of the car) piston on the right side of the engine.
