Want this question answered?
rotor will point to #1 at TDC.
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.
rotor should point to cylinder #1
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.
With the #1 cylinder on top dead center (TDC) of the compression stroke, the rotor should point to #1 on the distributor cap.
Yes, if #1 is at TDC on the compression stroke.
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)
If the distributor has been out of the truck recently, could be it wasn't reinstalled correctly. If the distributor has not been disturbed, sounds like a timing chain problem. ANOTHER ANSWER: Every time the rotor turns one complete round the crankshaft will turn twice. Knowing that, the crankshaft will pass TDC TWICE while the rotor will only point to the #1 cylinder once. If the crankshaft is at TDC and the rotor is not pointing at #1 it may just be that the rotor is pointing directly opposite. If that's the case, just turn the engine by hand, once around until it's pointing at TDC again.
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
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.
First of all, you cant point a rotor button. Rotor buttons are mounted inside the distributor cap. You can point the rotor. The rotor is whats mounted on the distributor shaft and turns with the shaft. Remove the #1 spark plug. Disable ignition so engine doesnt start. With a helper bumping the starter, put your finger over the #1 spark plug hole and have helper bump starter until you feel air blowing by your finger. Now, using a large wrench or socket, manually turn the crankshaft and line up the timing marks to TDC. Your rotor should be pointing directly at TDC on cylinder #1. transman
If you turn the engine to TDC on the compression stroke, the distributor rotor will point at the terminal for #1. Most distributors have a mark (usually a 1) on them under the cap to indicate the #1 position for the rotor to point at. The cap tower directly above the rotor point at this position is for the #1 spark plug.
