At TDC, on the compression stroke, the rotor will will be pointing at the # 1 spark plug electrode on the distributor cap.
Iti Lathe
on top dead rotor should be pointing at #1
rotor will point to #1 at TDC.
Timing is the position of the distributor rotor in relation to the #1 spark plug wire lug on the distributor cap - when the #1 cylinder is at top dead center.
Each cylinder has a top dead center position.
piston not at top dead center both pulleys need to be lined up with marks
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
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.
Top dead center on an engine is defined as when the piston is farthest from the crankshaft. Bottom dead center is when the piston is closest to the crankshaft on the engine.
Top dead center. It is when a piston is at its highest position.
the piston in cylinder #1 at the top on the compression stroke
bring #1 piston to top dead center where both intake & exahust valves are in closed position
