REMOVAL & INSTALLATION
EXCEPT PREMIER AND MONACO
See Figures 1 through 9
- Disconnect the negative (-) battery cable from the battery.
- Unplug the distributor connector from the wiring harness connector.
- Loosen the distributor cap retaining screws.
- Lift the cap off of the distributor.
- Raise and safely support the front of the vehicle. Remove the wheel and inner splash shield.
- Rotate the engine crankshaft until the distributor rotor points toward the intake manifold plenum. Scribe a mark on the plenum in line with the rotor. The scribe line indicates where to position the rotor when reinstalling the distributor.
- Lower the vehicle.
- Remove the distributor hold-down nut.
- Carefully lift the distributor from the engine.
- Check that the O-ring is properly seated on the distributor. If the O-ring is cracked or nicked, replace it with a new one.
Insert the distributor slowly into the engine. Carefully engage the distributor drive gear on the camshaft. When the distributor is installed properly, the rotor will be in line with the previously scribed line on the air intake plenum. If the engine was cranked while the distributor was removed, establish the proper relationship between the distributor shaft and the number 1 piston position as follows:
- Rotate the crankshaft until the number one piston is at the top of the compression stroke. When the number 1 piston is at TDC on the compression stroke, both the intake and exhaust valves will be fully seated (the springs will not be compressed). Make certain that the piston is on its compression stroke, otherwise the timing will be completely off.
- Rotate the distributor rotor until it aligns with the number one rotor terminal.
- Lower the distributor into the engine opening, engaging the distributor drive with the gear on the camshaft. With the distributor fully seated on the engine, the rotor should be under the number 1 terminal.
- Install the distributor cap. Ensure that all of the high tension wires are firmly in the cap towers.
- Install the hold-down nut and finger-tighten.
- Attach the distributor electrical connector to the wiring harness connector.
- Connect the negative (-) battery cable to the battery.
- Set the ignition timing to specification-refer to General Information & Maintenance for this procedure.
See Figures 10, 11 and 12
All 1988-90 and those 1991 3.0L engines manufactured before October, 1991 are equipped with an unconventional type distributor; therefore, this procedure applies to the distributor assembly for these engines. Later 1991 3.0L engines (after October, 1991) and all of the 1992 3.0L engines utilize a distributorless type ignition. The procedures for these engines are covered later in this section.
The distributor rotor is attached to the front of the distributor drive which is indexed to the left camshaft. The distributor drive itself is a two piece assembly that is pinned together. The drive rides in an oil seal located in the engine timing cover behind the distributor housing. The engine timing belt cover must be removed to service the oil seal. Refer to Engine & Engine Overhaul for the procedures on removal and installation of the timing belt cover.
- Disconnect the negative (-) battery cable.
- Remove and label the distributor wires form the spark plugs.
- If necessary, remove the distributor cap shield from the distributor.
- Completely loosen the distributor cap retaining screws.
- Remove the distributor cap from the mounting housing. To ease the removal of the distributor cap, remove and label the spark plug wires from the distributor cap.
- Remove the mounting screws that attach the rotor to the distributor drive.
- Remove the rotor form the front distributor drive.
- Extract the dust shield from the distributor housing.
- Remove the camshaft bolt holding the front distributor drive to the camshaft.
- Remove the timing belt covers if further distributor component (distributor housing, camshaft bolt, front distributor drive, oil seal, rear distributor drive, or distributor drive alignment pin) removal is needed. Refer to Engine & Engine Overhaul for the removal and installation procedures for the timing belt cover.
- Separate the distributor drive into its two parts: the front and rear sections. It may be necessary to use a small drift punch and tap at the parting line to separate the two sections. Make certain not to lose the distributor drive alignment pin; it will be needed upon installation.
- The distributor drive seal is located behind the distributor housing.
- Remove the distributor housing mounting bolts and then remove the housing.
- Use a socket to push the old distributor drive oil seal out of the timing belt cover.
- Use the Chrysler special tool 6126 to install the new seal flush with the timing belt cover. When the distributor housing is reattached, the seal will be seated to the proper depth in the cover.
- Insert the distributor housing into the front of the timing belt cover. Tighten the two distributor housing mounting bolts until snug.
- Apply a coating of clean engine oil to the seal lips.
- Install the distributor drive rear section through the back of the cover, past the seal and up into the distributor housing.
- Align the dowel in the rear section with the dowel hole in the distributor drive front section, then tap them gently together.
- Install the timing belt cover to the engine. Refer to the procedures for this in Engine & Engine Overhaul of this information guide.
- Install the camshaft bolt.
- Install the dust cover into the distributor housing.
- Install the rotor to the front distributor drive with the three attaching screws. Tighten the three screws to 26 inch lbs. (3 Nm).
- Install the distributor cap and tighten the mounting bolts to 35 inch lbs. (4 Nm).
