What torque is specified for the distributor stator assembly screw?

Tighten the distributor stator assembly screw (and the octane rod screw) to 1.7-4.0 N·m (15-35 in-lb).

Can the drive gear on an EEC-IV distributor be replaced?

No. The drive gear on EEC-IV distributors is not released for service. If any nicks or cracks occur during disassembly or reassembly, a new EEC-IV distributor must be used, since the gear is matched to the distributor at assembly.

What lubricant should be used on the distributor shaft assembly?

Lubricate the shaft lightly with a coating of fresh motor oil or with Engine Assembly Lubricant D9AZ-19579-D (ESR-M99C80-A).

What special tool is used when inverting the distributor for gear installation?

Invert the distributor and place it in the Axle Bearing/Seal Plate T75L-1165-B, after placing a 1/2 inch deep well socket over the end of the shaft assembly.

What is different between 4.9L and 5.0L/5.8L/7.5L distributor installation?

On the 4.9L engine only, a gear thrust washer is installed on the distributor; on 5.0L, 5.8L, and 7.5L engines, a collar and collar pin are installed instead.

This is page 03-07-6 of the 1994 Ford Powertrain/Drivetrain service manual (Aug 1993 printing) covering Econoline, F-150, F-250, F-350, Bronco, and F-Super Duty. The page continues the Removal and Installation section for the ignition distributor, specifically the closed bowl distributor used on 5.0L, 5.8L, and 7.5L engines (4.9L similar). An exploded parts diagram (figure B5110-A) shows both disassembled and assembled views with callouts for the screws (2 required), shaft assembly, Hall effect vane stator switch assembly, rotary vane, octane rod, connector, and base assembly. The Installation procedure lists 13 numbered steps: inspecting the base housing for heat damage or cracks, positioning and securing the stator (screw torque 1.7-4.0 N·m / 15-35 in-lb), installing the octane rod, lubricating the shaft with Engine Assembly Lubricant D9AZ-19579-D (ESR-M99C80-A), using a 1/2 inch deep well socket and Axle Bearing/Seal Plate T75L-1165-B for reassembly, installing the gear thrust washer (4.9L only) or collar and collar pin (5.0L/5.8L/7.5L), and installing the drive gear. A CAUTION warns the EEC-IV distributor drive gear is not serviced separately—if nicked or cracked, the entire distributor must be replaced.
