If the engine has been rotated with the distributor removed, or if you are setting up a new or rebuilt Chevy small-block engine, use this basic three-step procedure to set the initial timing. This process involves syncing the crankshaft-rod-piston assembly contained in the engine block with the ignition timing system.Continue Reading
This step is easier with two people. Remove the spark plug from the number one cylinder, and place your thumb over the hole. Have a friend rotate the crankshaft using a wrench or breaker bar placed on the harmonic damper bolt. When you start to feel the pressure of the compression on your thumb, the piston is close to its maximum stroke, top-dead-center. At the moment when the pressure subsides, stop rotating the engine because the number one piston is in position.
Use tape or white-out to mark the distributor cap's post for the number one cylinder on the base of the distributor and on the bottom of the distributor cap. Position the rotor at the mark, and insert the distributor into the engine block. Next, position and install the distributor cap, also based on the marks indicating the number one cylinder position. The engine is now at zero degrees but may not start.
Reinstall the spark plug and wire and try starting the engine. Gradually, little by little, advance the timing by turning the distributor counter-clockwise until the engine starts. Now that the engine is running, install a timing light and perfect the timing by rotating the distributor. Be sure to tighten the distributor clamp.
To adjust an engine timing, warm the engine, loosen and turn the distributor to restore the harmonic balancer to its normal level, and retighten the distributor. Refer to the manufacturer's information before adjusting the engine timing of your vehicle.Full Answer >
To install a tachometer, find the tach wire, use a tach meter to verify that you have correctly located the tach wire, remove a dash panel to access the wiring behind it, connect the tach wire to the distributor, and then start the engine to make sure everything works properly. To complete this job, you need a tachometer, wire cutters and strippers, a ratchet and sockets, a screwdriver and a drill.Full Answer >
The distributor cap firing order defines the order in which the wires from the distributor cap need to be attached to the cylinders of a vehicle's engine to achieve the correct firing order. Different manufacturers and engines use different firing orders, and connecting the wires incorrectly may cause engine damage.Full Answer >
A car igniter is a component in the car's engine that is responsible for sending a signal from within the distributor to the ignition coil, making the spark plugs fire. It is also known as the ignition control module.Full Answer >
