turn creamy. The oil level will also have increased. If
the oil is emulsified, proceed to operation (5).

(2) Remove the fusible link that is positioned
third from the front of th e fusible link connection
block, located at the rear of the battery. Disconnect
the coil high tension lead from the coil. (3) Remove all of the spark plugs except one.
(4) Have an assistant operate the ignition switch
to rotate the engine and listen to the sound made by
the engine as it is being turned over. Move the spark
plug to a different cylinder and repeat the lest. By performing the same test on all cylinders, a
rough comparison can be made to determine if there
is any loss of compression in any cylinder. This will be
apparent by the different sound made by the engine as
it is being turned over.

Normally, if the compression is satisfactory the
cylinder with the spark plug installed will create a
resistance to the rotating engine.

However, if the compression is low in a particular
cylinder, the engine will tu rn over easily and smoothly
when that spark plug is in place.

(5) If the above checks show a loss of coolant
which is present in the engine oil or on the spark plug,
one or more of the following faults may be the cause:

Blown cylinder head gasket.
Cracked cylinder or cylinder head.
If the compression check showed any weak or
inconsistent compressions, in addition to the above
faults any of the following could also be the cause:

Broken piston{s)
Burnt or broken valve(s).
Provided the previous checks do not indicate an

internal leakage of coolant, proceed with the follow-
ing:

(6) Remove the distributor cap and, with the aid
of an assistant operating th e starter motor, check that
the rotor arm rotates as the engine turns over. (7) Remove the camshaft hous ing top cover and.
again with an assistant operating the ignition switch,
check that all the valves open and close as the engine
turns over.
If the rotor arm or valves do not operate with
engine rotation, one of the following faults may be the
cause:

Rotor arm does not turn but valves operate:
Distributor drive shaft broken.

Rotor arm and valves do not operate: Broken
camshaft drive belt. Sheare d crankshaft timing gear
drive key. Sheared camshaft liming gear drive dowel.

Provided that all the previous checks have been
performed correctly and the operator is satisfied that
none of the components are at fault, all that remains
is for the ignition and valve timing to be checked. It
should be noted, however, that if loss of valve timing
proves to be the fault, th e cause of this occurrence
must be sought and rectified.

(8) In order to check the valve timing it will be
necessary to remove the distributor cap and the
camshaft housing top cover and turn the engine
clockwise via the crankshaft pulley until No. 1 piston
is at TDC on the compression stroke. In this position
the valves of No. 1 cylinder should be closed, the
valves of No. 4 should be rocking and the distributor
rotor should be pointing to the No. 1 high tension lead
segment in the distributor cap.

8. STARTER MOTOR
Special Equipment Required:
To Renew Brushes — Soldering iron
To Renew Armature Bearings — Bearing puller
DESCRIPTION
Two types of starter motors are installed to the
range of vehicles covere d by this manual, either
Hitachi or Bosch.

The starter motor is the induced pole type with
four brushes and four pole shoes with field coils.

A solenoid switch is attached to the starter drive
end bracket. The solenoid plunger is connected to
the overrunning clutch and drive pinion assembly
through a lever and pivot arrangement.

When the solenoid windings are energized, the
plunger acting on the lever and pivot engages the drive
pinion with the flywheel ri ng gear and at the same
time closes the switch supplying power from the
positive lead of the battery to the starter motor field
coils and armature to operate the motor.

As the engine fires, the over-running clutch of the
drive pinion assembly prevents high speed rotation of.
and possible damage to, the starter armature if the
solenoid windings are not immediately de-energized
by releasing the ignition key.

The starter solenoid switch windings are energized
by the ignition switch.

TO TEST ON VEHICLE
Should the starter motor fail to operate when the
ignition switch is turned to the Start position, check
the following points:

Check the battery condition and state of
charge. Refer to the Battery heading for the correct
procedure.
Clean the battery terminals, taking particular
care to remove the scale from the positive ( + )
terminal post and terminal. Check the earth connection for tightness and
cleanliness.
Switch on the headlamps and turn the igni-
tion switch to Start. If the lamps dim but the starter
motor does not operate, it could indicate that a short
circuit has developed in the starting system. Check that the engine is not seized or that the
starter motor drive pinion and ring gear are not
locked as these conditions would -give the same
indications as above.

(5) If the lamps do not dim and the starter
motor does not operate, this would indicate an open
circuit such as a broken or disconnected wire or a
switch not operating.

If the vehicle is equipped with an automatic
transaxle, turn the ignition switch to Start and move
the selector lever through all the gear selection range.
If the starter motor operates in any position other
than N or P, the neutral safety switch is faulty.

(6) Check all the external wiring to ensure that
the fault is not external. If the external circuit proves
satisfactory, indicating that the problem is in the
starter motor, the unit will have to be removed and
tested.

TO REMOVE AND INSTAL
Disconnect the negative battery terminal.
Disconnect the wiring from the starter motor
solenoid. Remove the starter motor mounting bolts,
