Distributor Cap And Rotor; Removal & Installation - Ford Ranger Maintaince And Repair Manual

Never, under any circumstances, measure resistance by puncturing the spark plug wire.
5. If the measured resistance is less than 7000 ohms per foot of wire, the wire is good. If the measured
resistance is greater than 7000 ohms per foot, the wire is defective and should be replaced.

Distributor Cap and Rotor

1991−92 models with the 2.9L engine, and 1991−94 models with the 3.0L engine use a distributor
equipped ignition system. All other models use a distributorless ignition.
REMOVAL & INSTALLATION
Distributor Cap
1. As a precaution, label all of the spark plug wires with their perspective cylinder number.
2. Loosen the cap hold−down screws.
3. Remove the cap by lifting straight up to prevent damage to the rotor blade and spring.
If the plug wires do not have enough slack to allow cap removal, confirm that they are properly labeled
and remove them from the cap.
4. Installation is the reverse of the removal procedure. Note the position of the square alignment locator
and tighten the hold−down screws to 18−23 inch pounds (2.0−2.6Nm)
Distributor Rotor
1. Remove the distributor cap.
2. Pull straight up on the rotor to disengage it from the shaft and armature.
3. Installation is the reverse of the removal procedure. Align the locating boss on the rotor with the hole
on the armature, then insure that it is fully seated on the shaft.
