# 1 piston is on the driver's side front plug. Turn the engine over until that piston is at top dead center, (TDC) on the compression stroke. Now look inside the distributor. The rotor will be pointing at #1. At about 11 o' clock on the distibutor. www.boxwrench.com NEW ANSWER: The first answer is right, and if the Distributor is in correctly when you
look stright down on the cap #1 will be at 5oclock on the cap.
The # 1 position faces to the REAR and slightly towards the drivers side on the Ford 400 cubic inch V8 engine distributor cap
Remove # 1 Spark Plug Rotate Engine Until #1 Is At Top Dead Center. Both Exh & Intake Valves Closed. Remove Cap, Check Rotor Button. It Will Be Pointing Where # One Goes. If You Are Not This Far Into A Problem. The Number One Cylinder Is The First One On Your Right Facing The Engine. Follow The Wire This Is Where It Is In The Cap.
There should be a # 1 mark on the distributor cap The distributor cap is installed with the # 1 position facing the engine , slightly towards drivers side The distributor rotor rotates COUNTER CLOCKWISE and the spark plug firing order is ( 1 - 5 - 4 - 2 - 6 - 3 - 7 - 8 )
first of all you need to know what kind of engine you are working on
On the distributor shaft, there is a painted mark, aline this with the two holes in the distributor shaft, located just below the gear. Mark the outside of the distributor where the rotor is pointed. On the inside of the distributor, you will find two cast marks, one stamped with an 8 and the other with a 6. For V-8's rotate the rotor until it is aligned with the 8. Now mark this location on the outside of the distributor. They should be about 45 degrees apart. The first mark is the direction the rotor should be pointing when you begin to install the distributor. When the distributor is fully seated, the rotor should be pointed to the 8 and the second mark. Snug the distributor into place and place the distributor cap on and tighten the screws for the cap. The plug wire post should be perpendicular to the center line of the engine.
On number one terminal, put engine at tdc on 1. If engine/rotor hasn't moved, leave rotor alone.
If you have spark at all but one plug, the problem is with that plug, wire, cap or rotor.
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.
Standard is that it is pointing at the number one position on the distributor 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.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.
You need to find TDC then remove cap and see where rotor button is pointing.
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.
If you will remove the #1 plug, (driver's side front of engine), then turn that cylinder to top dead center, (TDC), on the compression stroke, you can then remove the distributor cap and look at the rotor. The rotor will now be pointing to the #1 plug position. GET THE NUMBER ONE CYLINDER TOP DEAD AND THE ROTOR IN THE DISTRIBUTOR SHOULD BE PIONTING AT IT
all you should have to do is take the distributor cap off, and there it is. answer take the distributor cap off, pull the old rotor off, put the new one on, put the cap back on.
It's the distributor rotor that you are looking for & it's under the distributor cap. Remove the distributor cap and there you will find the rotor.
i think it's right in front and center
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
