How to tell when engine is close to top dead center?
Note: If this is being performed by one person, the alignment mark on the camshaft sprocket can be used to determine when the engine is close to Top Dead Center (TDC). However, the flywheel should be used for final alignment in case the timing is off slightly.
What does top dead center mean on a buggy?
Top Dead Center refers to the piston being at the very top of its travel in the cylinder. Otherwise known as “TDC”. This position is important when installing a new camshaft, because the cam must be set with the crankshaft at TDC. If the camshaft is off by a tooth, the engine will lack power and risks damage to the piston and valves.
What’s the best way to find the top dead center?
Doing so can be easy with ordinary hand tools, but using a piston stopper tool specifically designed to help find top dead center will yield the most accurate results. Disconnect the battery. Before beginning the project, use a hand or socket wrench to loosen the nut holding the black “ground” cable on the negative terminal of the battery.
What does top dead center mean on spark plugs?
Over time, this tends to get misaligned somewhat, resulting in a less-than-optimum spark plug firing time. The distance before the “top dead” center is the ignition timing, and it’s represented by a row of graded numbers on the balancer or flywheel through an access hole.

Where are the timing marks on a crankshaft?
Look for the camshaft timing marks located on the gears. They are usually clearly marked in the form of notches, pins or sometimes stamped words. Note: If you are unable to identify your timing marks, refer to a service manual for guidance to ensure that the engine is set to proper top dead center. Step 5: Turn the crankshaft pulley.
