Ignition systems 5B.5
Continue until the timing setting is correct,
then tighten the distributor bolts to the
specified torque.
5.5b Ignition timing marks - G40 models
to Section 4 and slacken the distributor
retaining bolts. Note: Mark the relationship
between the distributor body and the cylinder
head with a dab of paint, before adjustment is
attempted. This gives a reference point that
can be reverted to if the timing setting is lost.
7 Turn the distributor by a small amount
clockwise to advance (or anti-clockwise to
retard) the ignition timing. Tighten the bolts
lightly and repeat the timing light test.
Note: This sensor is fitted to the G40 model
(engine code PY) only.
Removal
1 The knock sensor is located on the rear of
the cylinder block, below the inlet manifold.
2 Ensure the ignition is off, then unplug the
wiring from the sensor at the connector.
3 Slacken and withdraw the mounting bolt
and lift off the sensor.
Refitting
4 Refitting is a reversal of removal, but note
that the sensor’s operation will be affected if
its mounting bolt is not tightened to the
correct torque.
Removal
1 With reference to Section 4, remove the
distributor cap and its screening shield (where
applicable).
2 Pull the rotor arm from the end of the
distributor shaft (refer to illustration 4.7a).
3 Inspect the distributor shaft contacts and
clean them if necessary, using contact
cleaning solution - do not use abrasive paper
or a wire brush as this will accelerate contact
wear.
Refitting
4 Refitting is a reversal of removal - ensure
that the rotor arm alignment lug engages with
the recess in the distributor shaft, before
refitting the distributor cap.
