This way, once you have found the TDC, do the operation for which you accessed TDC and put everything back in order, such as the spark plug.

Where to find the top dead center on a compression stroke?

As a general reference point, or when installing a distributor, Top Dead Center (TDC) on the compression stroke is required. Usually it can be found by looking at timing marks; but on some engines these marks may be lost or hidden.

Where is the dead center mark on a crankshaft?

Continue to turn the crankshaft until the zero or top dead center mark on the pulley matches up with the pointer on the 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.

When to set engine to top dead center ( TDC )?

Procedure NOTE 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.
