Use your finger over the no. 1 spark plug hole & turn engine over until you feel air or it blows your finger out of hole then look at your timing marks on crankshaft pulley it should be coming up on top dead center just set the mark on your pulley on - 0- this is top dead center on compression stroke.
how do you set tdc on 2004 kia Rio
the number one piston is on the left of you when facing the vehicle, it is the right side or passenger side and it must be at TDC for timing settings. (FENIX)
Number one cylinder is located driver's side front of engine. With the # 1 piston at TDC on the compression stroke, the rotor will be pointing at #1 plug on cap.Number one cylinder is located driver's side front of engine. With the # 1 piston at TDC on the compression stroke, the rotor will be pointing at #1 plug on cap.
To find where number one spark plug wire connects to the distributor, remove the distriutor cap and set number one piston at Top Dead Center (TDC). At TDC, the rotor should be pointing to where number one spark plug wire connects.
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
TDC is top dead center it pretains to the position of the pistons. The number one piston has to be TDC when you put on the timing chain or belt for it to work properly.
TDC is when the piston is at top dead center of the compression stroke. The easiest way to set it at TDC is to remove spark plug number one and insert a slim item such as a pencil or screwdriver into the spark plug hole and turn the crankshaft clockwise with a ratchet or breaker bar as you watch when the piston starts coming up. Remove the pencil or screwdriver and inseret your finger tip into the plug hole to feel for pressure (compression) building up. When you feel compression building up, remove your finger and re-insert the pencil or screwdriver to see when it reaches the top; the piston will be at TDC and the timing marks should be aligned. NOTE: The crankshaft rotates twice for each time the piston is at TDC.
once the number 1 piston is on tdc which ever point the rotor is facing becomes the number one position. if you conect the wires from there and follow your firing order you should have no problems.(i have done it)
The marks on the chain and the sprockets are set in such a way that the chain is installed at 50 deg after tdc. This is done so that the pistons are not at tdc where they could hit the valves while trying to install the chain. The marks are the only thing after tdc. When the chain is installed properly, the valves and pistons will be in proper time and the valves will be closed when the piston is at tdc. All you have to do is ine up the plated links on the chain with the proper marks on the sprockets.
This refers to when the spark plug fires on number one cylinder. All cylinders will fire at the same point in the stroke, but number one is used to set the timing. There is a notch or line on the crankshaft pulley that marks when the number one piston is at the top of the stroke. The timing is set before TDC so that the fuel can ignite before the piston reaches the top of the cylinder. This gets the most out of the explosion of the fuel. Timing is different for each make of engine, but usually 6-8 degrees before TDC.
this can be done by simple removing the dipstick and placing it into the number one plug hole after removing the plug turn the crank and allow dipstick to gently slide to tdc whilst ensuring crank marks are alligned with engine front plate marks.
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
