Chrysler Le Baron, Dodge Dynasty, Plymouth Acclaim. Manual — part 289
INSTALLATION
(1) Position distributor in engine. Make certain that
the O-ring is properly seated on distributor. If O-ring is
cracked or nicked, replace it with new one.
(2) Carefully engage distributor drive with auxiliary
shaft drive. When distributor is installed properly,
rotor will be pointing toward cylinder block. If engine
has been cranked while distributor is removed,
establish proper relationship between the dis-
tributor shaft and Number 1 piston position as
follows:
(a) Rotate the crankshaft until number one piston
is at top of compression stroke. Pointer on clutch
housing should be in line with the O(TDC) mark on
flywheel.
(b) Rotate rotor to a position just ahead of the
number one distributor cap terminal.
(c) Lower the distributor into the opening, engag-
ing distributor drive with drive on auxiliary shaft.
With distributor fully seated on engine, rotor should
be under the cap number 1 tower.
(3) Install the distributor cap. Ensure all high ten-
sion wires snap firmly in the cap towers.
(4) Install hold-down arm screw and finger tighten.
(5) Install splash shield.
(6) Connect distributor pick-up connector lead wire
at wiring harness connector.
(7) Set ignition timing to specification. Refer to Ig-
nition Timing.
DISTRIBUTOR PICK-UP—2.2L TBI, 2.5L TBI AND
2.5L MPI ENGINES
REMOVAL
(1) Remove splash shield and cap. Refer to Distribu-
tor Removal.
(2) Remove rotor from shaft (Fig. 15).
(3) Remove Hall effect pick-up assembly (Fig.
16).
INSTALLATION
(1) Place pick-up assembly into distributor housing
(Fig. 16).
The distributor pick-up wires may be damaged
if not properly reinstalled.
(2) Install rotor (Fig. 15).
(3) Install cap and splash shield. Refer to Distribu-
tor Installation.
DISTRIBUTOR SERVICE—3.0L ENGINE
REMOVAL

(2) Loosen distributor cap retaining screws.
(3) Lift cap of off distributor (Fig. 18).
(4) Rotate engine crankshaft until the distributor
rotor points 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.
(5) Remove distributor hold down nut (Fig. 19).
(6) Carefully lift the distributor from the engine.
INSTALLATION
(1) Position distributor in engine. Make certain
that the O-ring is properly seated on distributor. If
O-ring is cracked or nicked replace with new one.

(2) Carefully engage distributor drive with gear on
camshaft. When the distributor is installed properly,
the rotor will be in line with previously scribe line on
air intake plenum. If engine was cranked while
distributor was removed, establish proper rela-
tionship between the distributor shaft and Num-
ber 1 piston position as follows:
(a) Rotate the crankshaft until number one piston
is at top of compression stroke.
(b) Rotate rotor to number one rotor terminal (Fig.
20).
(c) Lower the distributor into the opening, engag-
ing distributor drive with drive on camshaft. With
distributor fully seated on engine, rotor should be
under the number 1 terminal (Fig. 20).
(3) Install distributor cap. Ensure sure all high
tension wires are firmly in the cap towers.
(4) Install hold-down nut and finger tighten.
(5) Connect distributor electrical connector to wiring
harness connector (Fig. 17).
(6) Set ignition timing to specification. Refer to Ig-
nition Timing in this section.
DISASSEMBLY
(1) Remove distributor cap mounting screws (Fig.
18).
(2) Remove distributor cap and inspect for flashover,
cracked carbon button, cracked cap, or burned termi-
nals. If any of these conditions exist, replace cap.
(3) Remove rotor screw (Fig. 21). Inspect rotor for
cracks or burned electrode. If any of these conditions
exist, replace rotor.
(4) Remove protective cover from distributor hous-
ing (Fig. 22).
(5) Remove lead wire clamp screw and remove lead
wire (Fig. 23).
(6) Remove disk assembly screw (Fig. 24).
(7) Remove disk spacers and disk (Fig. 25). Disk
and spacers are keyed. Check disk for warpage,
cracks or damaged slots (Fig. 26).
(8) Remove bushing and photo optic sensing unit
fasteners. Remove unit from distributor housing (Fig.
27).
(9) Remove bearing retainer screws (Fig. 28).
