Admin How do I know if my cylinder 1 is TDC?
Once the top dead center timing mark is lined up with the marker on the engine, the motor should now be at top dead center. To verify, shine the flashlight down into the spark plug hole. You should be able to see the top of the piston clearly near the top of the cylinder.
How do you tell if your distributor is 180 out?
You can determine if it is 180 out by removing #1 plug and placing your finger/thumb over the hole. (Temporarily remove the wire from the coil first) Have someone “tap” the starter and you will feel pressure trying to to blow your finger away. This is the compression stroke. Note the direction of engine rotation.
Are all distributor gears the same?
According to Hodgdon, “The four most common types of distributor gears are composite, bronze, cast-iron, and hardened steel. These gears conform well to the mating camshaft, and will not damage the cam gear. Since cast iron contains two percent carbon, these gears work well with cam gears made from the same material.
How can you tell if a piston is at TDC?
You can turn the crankshaft back and forth (by hand ) while observing motion of the ( screwdriver; coat hanger or straw ) to get a better idea of the location of the piston. When you see it has reached its highest point of travel, it is at (TDC).
Where should the rotor point at TDC?
The rotor button should be pointing to the number 1 position on the distributor cap when the number 1 piston is at top dead center (on the compression stroke). The pistons come up two times during the combustion cycle.
Can a distributor be installed 180 degrees out?
As long as you set 1 to TDC and it is coming around to fire it should be fine. Might have to change plug wires or swap some that are too short, but keep the firing order the same and it should be fine. Just move all the wires around 180 degrees, and re-set the timing you are good to go.
