Procomp PC7000 Distributors are a 2-wire hook up, designed to eliminate all the clutter.

NOTE:  Procomp distributors can be used with roller cams.

Procomp also manufacture bronze gears which are specifically designed for roller cams.

MATERIAL SELECTION NOTES:

• Cast Iron gears are compatible with cast iron camshafts (hydraulic or solid flat tappet type).

• Steel gears are compatible with billet steel camshafts (hydraulic roller tappet type).

• Bronze gears can be used with either cast iron or billet steel camshafts. They are usually recommended by manufacturers of aftermarket billet steel solid roller tappet camshafts. Since the bronze is softer than cast iron or steel, it will wear at a faster rate.

Step 1 – Unpack the distributor carefully and inspect it for possible shipping damage. Inspect again after removing the cap.

Step 2 – Remove number one spark plug and have someone crank the engine over to find Top Dead Center (TDC).

Step 3 – Tap engine around until desired cranking advance is displayed on timing tab and or balancer.

Step 4 – Lower distributor into position. The rotor should be aimed at number one cylinder, you may find that it hasn’t seated firmly against the support boss. This indicates that the lower end of the distributor shaft is not properly aligned with the oil pump drive rod. Do not attempt to force the distributor into position. You will need to rotate the oil pump drive manually until the distributor fully seats.

Step 6 – With the distributor properly seated, rotate the distributor so that one of the plug wire terminals lines up with the tab on the rotor. This will be the #1 plug wire location. Tighten the hold-down bolt just enough so that the distributor is held in place, but can still be rotated with a little effort.

Step 7 – After all wires have been installed, Put on the distributor cap.

Step 8 – Connect the wiring leads as described below.

Step 9 – Connect timing light. Start the engine and allow it to warm up sufficiently to idle smoothly. It may be necessary to rotate the distributor (either clockwise or counter-clockwise) before a smooth idle can be achieved. If the engine will not idle smoothly, the firing order may be incorrect or the rotor may not have been properly aligned during installation. Consult a service manual for corrective procedures.

Step 10 – Consult the appropriate service manual to determine the factory – recommended initial timing and idle speed. Set initial spark timing with the vacuum advance line disconnected. Advancing timing two to four degrees from the factory setting beyond factory specifications may result in detonation, which can cause engine damage. Listen carefully – if you hear the engine knocking or pinging, retard initial timing as required to eliminate it.

 

Testing and Troubleshooting:

There are only three parts to troubleshoot in this type of ignition system.

1. Magnetic Pickup.

2. Ignition Module.

3. Coil

1. The first and easiest thing to test is the coil. Either test it manually by supplying 12 volts to the positive side and momentarily grounding the coil or swap it out with another.

2. Now that you know the coil is good we can test the pickup and module. To test, simply take the coil wire off the distributor cap and connect it to a spark plug that is grounded to the engine block. Remove the distributor cap. Disconnect the mag pickup wires from the ignition module. Using a jumper lead short the two module pins together momentarily and when you remove the jumper the spark plug should fire. If you do have spark, then replace the magnetic pickup; if not then replace the module.

Note: Make sure distributor is grounded sufficiently through the engine.
