V) Apply a layer of grease to the recess of the ignition timing sensor rotor drive shaft and install the plug in its end.
4. Establish springs of a centrifugal regulator of an advancing angle of ignition.
5. Install base plate ("breaker plate") and an ignition timing sensor induction coil.
A) Align the notches of the base plate and the breaker body, and install the base plate and induction coil.
b) Secure the base plate with two flat washers with screws.
6. Establish a rotor of the gauge of the moment of ignition.
Align the slots and slide the sensor rotor with the new spring onto the drive shaft.
7. Check the air gap (see page 62).
- Gap size: 0.2 - 0.4 mm.
8. If necessary, replace the base plate and ignition timing sensor induction coil.
A) Remove the rotor, base plate and ignition timing sensor induction coil (see above).
b) Use kerosene or petrol to clean the threaded holes and screw threads.
V) Install new base plate ("breaker plate").
G) Lubricate the thread ends with anaerobic glue for a length of 3-5 mm.
d) socket wrench (hexagon) fasten the new sensor induction coil with screws in such a way as to ensure the required air gap.
Recommendation: after installing a new ignition timing sensor, do not start the engine for at least 30 minutes.
9. Install the connecting wire of the distributor.
Fasten the wire terminal and capacitor to the distributor housing.
10. Establish a vacuum regulator of an advancing of ignition.
Connect the regulator rod to the pin on the base plate and fix the regulator with two screws on the distributor body.
11 Install the switch.
A) Secure the switch case with two screws. Connect the three wires to the switch terminals with three screws as shown in the figure.
b) As shown in the figure, secure the wires of the ignition timing sensor induction coil with clamps to provide the necessary slack.
Attention: the wires must not touch the rotor of the ignition timing sensor and the distributor housing.
12. Install the ignition coil.
A) Install the gasket and ignition coil with four screws.
b) Connect the four wires to the switch terminals with two screws as shown in the figure.
Attention:
