You have to rotate the crank to where the #1 cylinder is coming up on the compression stroke and set it to TDC at the timing pointer. Try to not go past TDC. If you do you have to make a couple of more turns to get it back up to TDC. Do not go backwards with the crank when setting the initial timing.

How do you adjust the TDC on a harmonic balancer?
Look at your harmonic balancer. If the TDC mark is not lined up with the timing pointer, then you will need to rotate the engine in its normal running direction with a socket and ratchet or breaker bar placed on the harmonic balancer bolt. Turn the engine carefully, exactly lining up the TDC mark with the timing pointer.
Where is the harmonic balancer on a car?
At the front of the engine you will find a pulley that will drive the belts to run the water pump, alternator, power steering pump, air conditioner, etc. This pulley is called the 'Harmonic Balancer' and is actually 2 pieces pressed together on a rubber bush which acts as a 'shock absorber' for the engine.

This pulley is called the 'Harmonic Balancer' and is actually 2 pieces pressed together on a rubber bush which acts as a 'shock absorber' for the engine. This pulley is marked with several lines to indicate the position of the engine rotation, measured in degrees.

What is BTDC ignition timing?
"Timing advance" refers to the number of degrees before top dead center (BTDC) that the sparkplug will fire to ignite the air-fuel mixture in the combustion chamber before the end of the compression stroke.
What happens if ignition timing is too advanced?
If the ignition time is set too advanced then the charge gets combusted during the compression stroke, resulting in the peak pressure achieved inside the engine during the compression stroke. This peak pressure opposes the movement of the piston toward TDC. Thus it results in loss of power and chances of knocking.

Does advancing timing increase idle?
Our experience shows that connecting the vacuum advance to a manifold vacuum source will add timing at idle and improve idle quality in gear with an automatic transmission. Milder applications can also benefit from this idea but will require some experimentation.

What is 10 degrees before TDC?
We use a dial caliper to make marks on a length of masking tape starting with 0 – or TDC. This means that at 10 degrees, the distance will be . 695 inches and so on.
Is 4 degrees before top dead center?
With the above factors in play, the ignition must be timed so the spark begins the fuel burn sometime before top dead center, or BTDC in engine parlance. This is measured in degrees of rotation. Most engines set ignition timing somewhere between zero and 20 degrees before top dead center. This is called base timing.

How many bolts are needed to install harmonic balancer?
Unless I'm confused to install ONLY the harmonic balancer its just the 4 bolts that hold it on to the crank and the centerbolt. As long as the belt wasn't wasn't removed it does not matter if the crank rotates any direction. As long as the timing belt wasn't removed then there should be no need to worry about mechanical timing.
Do timing belts have a memory?

What is harmonic balancer?
harmonic balancers by design have a rubber insertion between the hub and the pulley. that rubber breaks and relies soley on friction to drive the pulley. it the tdc mark and the piston position are not correct , that would indicate that the harmonic balancer needs replacing.
How do you set TDC?
