SERVICE POINTS OF REMOVAL
l-4. CAUTION OF SPARK PLUG CABLES17. HIGH TENSION
CABLE
The cable is to be pulled out by grasping the cap part.
9. REMOVAL OF DISTRIBUTOR
Before removing the distributor, position the piston in No.
1 cylinder at the top dead center on compression stroke by
the following procedure.
(1) Remove the cap from the distributor.
(2) Turn the crankshaft until the distributor rotor lines up
with the No. 1 spark plug cable electrode on the
distributor cap.
(3) Align the notch on the crankshaft pulley with the timing
mark “T” on the timing indicator to set the engine
SO
that the piston in No. 1 cylinder is at the compression
top dead center.
INSPECTION
CLEANING AND INSPECTION OF SPARK PLUGS
1. Pull the spark plug cables out of the spark plugs.
2. Using a spark plug wrench, take all the spark plugs out of the
cylinder head.
Caution
Ensure that no foreign bodies fall from the spark plug
holes.
3. Using the following criteria check that there is no electrode
spark loss, that there is no damage to the outer insulation, and
that sparking is good.
l Existence of insulation damage
l Spark dissipation
l Carbon accumulation
Using either plug cleaner or wire brush, clean both the up-
per part and the glass part.
l Damage to or breakage of gaskets
l Spark action in spark glass area
In cases where there are black deposits due to carbon, this
indicates excessive passage of mixed gases so that air in-
take becomes extremely deficient.
Owing to the excessively large spark gap, spark loss and so
on can be expected.
In case of white scorching, this indicates an excessively
thin gas mixture and prolongment of sparking time, which
suggests poorly fitted plugs.
