At TDC compression it points to the number one post on the cap.
Crank on tdc#1. point rotor in distributor at the line on the pick up plate.Crank on tdc#1. point rotor in distributor at the line on the pick up plate.
At tdc compression it should be pointing at #1 on the distributor cap.
rotor should point at number 1 plug lead when engine is at tdc make a mark with whiteout ,on outside of distributor before you remove distributor cap. make this mark where the #1 spark plug lead would be if distributor cap was on distributor when you remove cap this is where rotor needs to be pointing
The rotor inside the distributor should be pointing at the #1 spark plug.
When the engine is at Top Dead Center (TDC) on the compression stroke, the distributor rotor should point towards the terminal corresponding to the cylinder that is currently firing. This ensures that the ignition spark is delivered to the correct cylinder at the right moment in the engine cycle. If the engine is on TDC for a different cylinder (like the exhaust stroke), the rotor will not point to the correct terminal. Always ensure proper timing alignment during distributor installation.
With the #1 cylinder on top dead center (TDC) of the compression stroke, the rotor should point to #1 on the distributor cap.
rotor will point to #1 at TDC.
Set the #1 cylinder at TDC on the compression stroke. Adjust distributor so that the rotor point directly at the #1 spark plug wire in the distributor cap. Any deviation will be corrected by the PCM. You're done.
When installing a distributor in a motor, the rotor button should point to the terminal of the ignition wire for the number one cylinder at top dead center (TDC) on the compression stroke. This ensures that the ignition timing is correct when the distributor fires. It's essential to confirm that the engine is at TDC on the compression stroke, not the exhaust stroke, for accurate timing. Proper alignment ensures optimal engine performance.
5 degrees before TDC
WHEN INSTALING THE DISTRIBUTOR THE ROTARY BUTTON HAS TO BE POINTING AT THE NUMBER 1 CYLINDER AT TDC
The distributor is set to 0 deg. Align the rotor to the line in the pickup plate in the distributor when the crank is at tdc. The dist. is then fine tuned with a scan tool.
