How to find the mark for a TDC?
To correctly align the mark for TDC you need to be looking directly down on the opening. Many people have trouble locating the opening in the clutch housing for the TDC mark. You’ll note in the picture the close proximity of the opening to the speed/reference sensor mounting bracket (sensors removed in this picture).
How can I tell if my engine is at TDC?
So, after you get the crankshaft (by flywheel indication or by checking actual piston location), check the camshaft sprocket to make sure the camshaft alignment mark is at the TDC position as well. This procedure can be performed by one person. However, it is much easier to perform with two people.
When to set engine to top dead center ( TDC )?
When setting the engine to TDC on the compression stroke for cylinder #1, you must realize that the crankshaft rotates twice for every single rotation of the camshaft. So, if you simply set the crankshaft to TDC without looking at the position of the camshaft, you may actually be at TDC on the exhaust stroke for cylinder #1.

Where do you find the dead center mark on an engine?
For most engines, the zero or top dead center mark will be the first mark, or will be clearly marked in a different color or manner than the other marks on the pulley. Note: If you are unsure of which mark indicates your engine’s top dead center, refer to a service manual to ensure that the engine is turned to the correct position.
How is the TDC of a piston determined?
TDC (Top Dead Center) means the upper most position of piston in the cylinder of an engine. It is the point from which ignition system measurements are made and the firing order is determined. Engineers are using different methods to find out the TDC of an Auxiliary engine. Here you can have a look at some of the methods to find out the TDC. 1.
