rotor will point to #1 at TDC.
on top dead rotor should be pointing at #1
With the #1 cylinder on top dead center (TDC) of the compression stroke, the rotor should point to #1 on the distributor cap.
if the number one piston is at top dead center the rotor should point at number one spark plug wire and rotate toward the next spark plug wire in the firing order.
As on any automobile engine, the rotor turns in a 360 degree circle. When the piston for the number one cylinder is at top dead center on the compression stroke the rotor should point to the number one spark plug tower of the distributor cap.
Turn the engine over until the #1 piston is at top dead center (TDC) on the compression stroke. The rotor will then be pointing to the # 1 plug connection.
At TDC, on the compression stroke, the rotor will will be pointing at the # 1 spark plug electrode on the distributor cap.
When the #1 piston is at TDC./ TOP DEAD CENTER on the compression stroke the rotor should be pointing towards the #1 cylinder when the distributor is installed correctly.
The top dead center is when the piston has reached its peak and can go no farther up, it has reached its summit. The bottom dead center is when the piston is at its lowest point.
it will be facing the number one cylinder plug wire on distributer cap,#1 cyl will be the one at the front on the driver side
Top Dead center is when #1 cylinder is at its upper most point in its stroke
wire that as number one or pull dist. and fix.
