-lgnition Timing Inspection and Setting
1.Check the idle speed, and adjust it it necessary (see
section 'l '1 ).
Pull out the service check connector 2P (BRN and BLK
wires) from the connector holder located under the
dash on the front passenger side, then connect the
SCS service connector (T/N 07PAZ - 0010'100) to it.
Start the engine. Hold the engine at 3.000 rpm with
no load {A,/T in E or E. M/T in neutral) until the
radiator fan comes on, then let it idle.
Connect the timing light to the No. 1 ignition wire,
then point the light toward the pointer on the timing
belt cover.
Check the ignition timing in no load conditions:
headlights. blower fan, rear window defogger, and
air conditioner are not operating.

6. Adjust the ignition timing if necessary, as follows.
Loosen the distributor mounting bolts. and turn the
distributor ignition (Dl) housing counterclockwise to
advance the timing, or clockwise to retard the tim-
ing.

the ignition timing.
Disconnect the SCS service connector from the ser-

Distributor Replacement
Removal:
1. Disconnect the connector from the distributor.
2. Disconnect the ignition wires from the distributor
ignition {Dl) cap.
3. Remove the mounting bolts from the distributor,
then remove the distributor from the cylinder head.

lnstallation:
NOTE: Before you install the distributor. bring the No. 1
piston to compression stroke TDC.
1. Coat a new O-ring with engine oil, then install it.
2. Slip the distributor into position
NOTE: The lug on the end of the distributor and its
mating grooves in the camshaft end are both offset
to eliminate the possibility of installing the distribu-
tor 180" out of time.
3. Installthe mounting bolts, and tighten them lightly.

JRectifier Removal
1. Remove the four through bolts.
Heat the rear bearing seat with a 1,000 W hair drier
tor about five minutes (120 - 140'F, 50 - 60"C).
3. Separate the rear housing from the drive-end hous-
ing by inserting a flst tip screwdriver into the open-
ings and prying them a part. Be careful not to dam-
age the stator with the tip of the screwdraver.
Seoarate the rear housing and drive-end housing
with the stator attached to the rear housing.

Charging System
Rectifier Removal (cont'd)
Separate the rear housing from the stator/rectifier
assembly by removing the four screws and the ter-minal nut.
TERMINAL NUT
Unsolder the rectifier from the stator leads,. To avoid damaging the diodes with heat, pinch
the stator leads between pliers to carry heat off,and apply the soldering iron only long enough toseparate the leads from the rectifier.. Use a 100 W soldering iron.
STATOR SOLDERING
7. Install the new rectifier in the reverse order of removal.. Apply the soldering iron only long enough toensure a good connection so the heat will notdamage the diodes.
a Use only a rosin core type solder or solder joints
will corrode.

Rectifier Test
NOTE: The diodes are designed to allow current to pass
in one direction while blocking it in the opposite direc-tion. Since the alternator rectifier is made up of ninediodes, each diode must be tested for continuity in bothdirections with an ohmmeter that has diode checkinocapability; a total of 18 checks.
1. Check for continuity in each direction between- the B and P terminals.- the B'and P terminals.- E {ground) and the P terminals.
All diodes should have continuity in only one direc-UOn.
lf any of the diodes fails, replace the rectifier assem-bly, (Diodes are not available separately.)

JRotor Slip Ring Test
1. Check the resistance betlveen the slip rings
There should be 1 8 - 3 0 ohms
. lf resistance meets the specification, go to step 2.
. lf resistance does not meet the specification,
reolace the alternator'
SLIP BINGS
2. Check that there is no continuity between the slip
rings and the rotor or rotor shaft.
3. lf the rotor fails either continuity check, replace the
alternator.
Stator Test
'1. Check that there is continuity between each pair of
leads.
CORE
Check that there is no continuity between each lead
and the coil core.
lf the coil fails either continuity check, replace the
alternator.

Rear Bearing Replacement
1. Pull offthe rear bearing,
. Make sure the tips of the bearing puller jaws arethin enough to fit between the bearing and theslip rings.
. Do not reuse the bearing.
SLIP RINGSBEARING PULLER
Use a hand press to install the new bearing. Applypressure only on the inner race to avoid damaging
the bearino.

Alternator Reassembly
1. Push the brushes in, then insert a pin or drill bit(about 1.8 mm diameter) to hold them there.
Heat the rear bearing seat in the rear housing asdescribed on page 23-121. After heating, continueimmediately with assembling before the rear bear-ing seat cools completely,
Put the rear housing/stator assembly and drive-endhousing/rotor assembly together. tighten the fourthrough bolts and pull out the pin.
REARSTATOR ASSEMBLY
After assembling the alternator, turn the pulley byhand to make sure the rotor rotates smoothlv andwithout noise.
