If you are installing the timing chain on a 2.7L, the number one cylinder will not be at TDC. That is normal.If you are installing the timing chain on a 2.7L, the number one cylinder will not be at TDC. That is normal.
The TDC is when the number one cylinder is at the top or top dead center of the compression.
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.
Typically it is the one that points toward the number one cylinder. Technically it can be any of them as long as the wires are in the correct firing order. When cylinder number one is a tdc, the rotor should be pointing at the number one cylinder. Thus the number one plug wire.
Easiest way to find it is to set #1 piston at TDC and remove the distributor cap to see where the rotor is pointing. It should be pointing to #1 cylinder position in relation to the distributor cap.
there is no hard fast rule here. but typically with the cap off and number one cylinder at TDC on compression stroke. the rotor will point at number one cylinder on the engine.
No. When the timing mark is at tdc, #'s 1 & 6 are both up. One is up for compression, the other is up for exhaust.
if auto related it stands for top dead center and refers to the position of the crank in relation to the positon of the number one cylinder.
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.
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)
Top Dead Center, unless otherwise specified, refers to when the piston in cylinder number one reaches the closest it can be to the cylinder head. All the valves should be closed at this point.
I'm not sure what engine you have but on the 4ze1 which is what I have in my trooper having the arrows face both up (cam gear and crank pulley) means the engine is in tdc for the number 4 cylinder. If the arrows are facing one another it is tdc for number 1 cylinder.
