Re: EEC- III
OK, Found it!
This is for an EEC III with Duraspark III. The distributor has no wires on it, other than the plugs and coil wire. No vac advance unit on it. Has a Bi-Level cap and rotor. This means rotor has two spark paths - one high to 4 plugs, one low to 4 plugs, with underside of cap having two alternating matching levels. The coil is the familiar round cylindrical oil-filled style, not the E-frame type of later years.
Install Distributor:
To install distrib, match notch on holddown flange with clamp bolt hole in block. Do this while near TDC on comp. stroke of cyl. #1. The large slot on the top of the distrib. sleeve assembly (on top of shaft) should roughly line up with the notch in the Adapter. The Adapter is the middle section of the Distrib, that the cap fits onto. If the slot isn't close, pull out the Distrib and turn shaft slightly, and try again (meshing the next set of teeth).
Now here's the Check Procedure:
With cylinder #1 on Comp. stroke, rotate crank by hand until the rotor alignment tool can be inserted into the slot on the sleeve, and into the notch on the Adapter. The tool is a small rectangle of metal, that fills the width of the sleeve slot, and can fit into the notch on the Adapter. I'm sure you can fab something there.
Now read the timing mark down on the damper. If it reads within 4 degrees, plus or minus, of 0 TDC, thats it, your done. If not, read on...
Rotor Alignment Procedure:
Rotate crank to put cylinder #1 on 0 degree TDC on damper, being sure its in Comp. stroke.
Loosen the two screws on the sleeve assembly, and rotate the sleeve so tool can fit in slot on sleeve and notch on Adapter. Tighten screws to 25 - 35 lb.in. and remove tool.
The procedure is from a Ford manual. Since there is no pickup of any sort from this distributor, the EEC-III is using the blip from the Crankshaft Position Sensor (CPS), and the engine RPM, also from the CPS, along with temp, load, etc. etc. to predict when to fire plugs. So the Distrib in this setup is just a rotating switch to reach each plug. The EEC controls all advance/retard. And the rotor alignment keeps it in phase with what the EEC wants to do.
Hope this solves your problem.
