EEC III/DISTRIBUTOR - PROCEDURE FOR SETTING ROTOR ALIGNMENT 5.0L/5.8L EEC EQUIPPED LIGHT TRUCKS
LIGHT TRUCKS 1981/83 BRONCO, F-SERIES AND ECONOLINE
The following information and procedures are issued to clarify the proper setting of distributor rotor alignment on the subject vehicles. This reference
publication supersedes all other printed material on subject.
FIGURE 12
FIGURE 13
For 1981 through 1983 model year vehicles, EEC distributors used on the EEC Systems had the "second generation" rotor (Figure 12). The 1983 model
5.0L EEC equipped Light Truck employs a conventional rotor (Figure 13).
PROCEDURE FOR ROTOR ALIGNMENT:
1.
Remove the distributor cap and wires and position them to one side.
2.
Remove the rotor.
3.
To check rotor alignment:
a.
Rotate the engine until the No. 1 piston is on the compression stroke. NOTE: Verification of being on the compression stroke is essential to
correct rotor alignment. If the piston is on the exhaust stroke, the rotor can be misaligned by 180~.
b.
Slowly rotate the engine until the alignment tool can be installed.
