radiator NISSAN PULSAR 1987 Owner's Manual

Electrical System 197
Switch on all lamps and allow them to
illuminate for approximately five minutes to reduce
the charge of the battery and to apply a load to the
circuit.
Start the engine and gradually increase the
speed to approximately 2 500 rpm. The reading on
the ammeter should be approximately 75% of the
rated output of the altern ator. See Specifications.
Switch off all the lamps and run the engine at
1 500-2 000 rpm until the indicated charge is below
10 amps. The voltmeter should now read in excess of
13.6 volts.
NOTE: Should the alternator fail to reach
the specific output, the unit will have to be
removed and overhauled or a replacement
unit installed.

Should the voltage reading be above or
below Specifications, the regulator will have
to be renewed.

TO REMOVE AND INSTAL
Disconnect the negative battery terminal.
On 1.8 liter engines, remove the bolt secur-
ing the air cleaner intake duct and remove the air
cleaner intake duct. Drain the radiator by releasing the radiator
drain plug, located at the bottom of the radiator and
allow the coolant level to fall below the thermostat
housing level. NOTE: Refer to the Cooling and Heating
Systems section when refilling the radiator
coolant to its correct l
evel, failure to do so
could result in severe damage to engine
components.

Remove the retaining bolts securing the
thermostat housing, disconnect the hose from the
radiator and remove the thermostat housing and
radiator hose from the vehicle. Using a socket and extension bar, remove the
bolt securing the alternator to the drive belt tensioning
bar located under the alternator. On vehicles not equipped with air condition-
ing, remove the front splash guard from under the
front of the vehicle and remove the bolt securing the
alternator to the drive belt tensioning bar. Loosen the upper mounting bolts, slacken
the alternator drive belt and remove it from the
alternator pulley.
While supporting the alternator, remove the
upper mounting bolts and remove the alternator from
the vehicle. Installation is a reversal of the removal procedure
with attention to the following points:

Do not over tension the drive belt. Refer
to
the Engine Tune-up section for the correct belt
adjusting procedure. Ensure that the wiring and connectors are
securely located on the alternator.

correct procedure.

TO DISMANTLE
Bosch Alternator
Remove the alternator from the vehicle as
previously described.
Scribe a mark across the drive end bracket,
stator and slip ring end bracket to facilitate correct
alignment during assembly. Remove the screws and washers securing the
regulator and brush holder assembly. Withdraw the
regulator and brush holder assembly from the alter-
nator. Remove the long screws securing the drive
end bracket to the slip ring end bracket and withdraw
the drive end bracket, rotor and pulley assembly.
NOTE: Ensure that the wave washer behind
the rotor shaft rear bearing in the slip ring
end bracket is not mislaid.

Holding the rotor in a soft jawed vice,
remove the split drive pulley retaining nut, washer
and spacer from the rotor shaft. Remove the split driv e pulley, spacer, plate
washer and fan from the rotor shaft. Using a suitable pres s and press plates,
support the drive end bracket with the pulley end of
the rotor shaft uppermost a nd carefully press the rotor
shaft from the spacer, bearing and the drive end
bracket.
Remove the spacer and the bearing retainer
plate screws from the drive end bracket. Remove the bearing retainer plate and the
bearing from the drive end bracket. If necessary, using a bearing puller, remove
the rear bearing from the rotor shaft. Remove the nut, spring washer and output
terminal components from the {B + ) terminal on the
outside of the slip ring end bracket.

(12) Working inside the slip ring end bracket,
remove the screws securing the diode pack to the
bracket and withdraw the stator and diode pack as an
assembly. Remove the insulating spacer and washer
from the (B +) terminal.

NOTE: The diode pack is supplied as an
assembly and in the event of a component
'failure, must be renewed as a complete unit.

Mark all wiring connections prior to removal
to aid assembly. Where necessary, unsolder the stator leads
from the connector terminals to separate the diode
pack.
NOTE: When soldering or unsoldering the
stator leads from the diodes, grip the leads
with a pair of long nosed pliers. This will
safeguard the diodes by transferring any
excess heat to the jaws of the pliers.

Hitachi Alternator
Remove the alternator from the vehicle as
previously described.

Scribe a mark across the drive end bracket,
stator and slip ring end bracket to facilitate correct
alignment during assembly. Remove the through bolts retaining the drive
end bracket to the slip ring end bracket. Apply a heated 200 watt soldering iron to the
slip ring end bracket at the bearing mounting boss for
3-4 minutes to heat the bracket and allow the removal
of the slip ring end bearing. Carefully prise the slip ring end bracket and
stator assembly from the drive end bracket and rotor
assembly using suitable levers. Do not insert the levers
too far or damage to the stator will occur.
Hold the rotor and driv e end bracket assem-
bly in a soft jawed vice and remove the nut retaining
the drive pulley to the rotor. Remove the washer, pulley and spacer
washer from the rotor shaft.
Using a soft faced hammer, drive the rotor
shaft assembly from the drive end bracket and remove
the inner spacer washer from the rotor shaft.
Remove the bearing retainer plate screws
and remove the plate. Using a suitable drift, drive the
bearing from the bracket. Remove the retaining nut and insulator
washer from the alternator terminal. Remove the slip ring end bracket retaining
nuts and separate the diode pack, stator and regulator
assembly.
If necessary, file the ends of the brush
assembly retaining rivets, caref ully unsolder the ter-
minal plate and remove the brush assembly and
terminal plate from the diode pack. If necessary, remove the fan guide retaining

Using the radio/cassette removal tools during removal of the unit.
Construct the special tools as illustrated,
insert both tools into the release holes on the radio/
cassette and carefully withdraw the radio/cassette
from the mounting bracket.
Disconnect the wiring harness terminal plug
and remove the radio/cassette.
Installation is a reversal of the removal procedure
with attention to the following points:

Remove the special tools from the radio/
cassette, connect the wiring harness terminal and push
the radio/cassette into the mounting bracket. Install the release hole covers on each side
of
the radio/cassette.

and remove the headlamp from the vehicle. Installation is a reversal of the removal procedure.

To Adjust Headlamp Aim
Ensure that the tires are inflated to the
correct pressure and that the vehicle is positioned on
level ground.
The vehicle should be unladen, with a full
fuel tank and the driver sitting in the vehicle. When using a headlamp aiming machine,
refer to the manufacturers instructions for equipment
being used.

4. ENGINE BONNET
TO REMOVE, INSTAL AND ADJUST
Raise the engine bonnet and place covers on
both front mudguards. Mark the hinge mountings on
the bonnet with a soft lead pencil to aid assembly.
Place a quantity of soft rag folded several
times under each rear corner of the bonnet on the
scuttle panel. Disconnect the windscreen washer hose from
the bonnet at the tee piece. With the aid of an assistant supporting the
bonnet, remove the retaining bolts and lift the bonnet
from the vehicle. Installation is a reversal of the removal procedure
with attention to the following points:

Holding the bonnet in the position previ-
ously marked, install the bonnet hinge bolts
and
tighten to just over finger tight.
Close the bonnet and by pushing with the
hand, position the bonnet evenly in its opening.

Open the bonnet carefully and tighten the
mounting bolts. Check for correct positioning and adjust
again if necessary. Check the adjustment of the bonnet catch.
When the bonnet is closed the bonnet should align
with the front panels. When the catch is released the
bonnet should pop up sufficiently to enable the safety
catch to be released. If adjustment is necessary, mark the base
position with a pencil, loosen the retaining bolts and
move the catch in the desired direction. Tighten the
bolts and recheck.
NOTE: When adjusting the bonnet catch
ensure that the bonnet striker plate is enter-
ing centrally into the catch. Adjust the catch
or the bonnet lunges if necessary.

(7) When adjustment is complete, adjust the
bump rubbers on the radiator support panel up or
down by turning them to support the outer edges of
the bonnet.
