For removal of the stator unit refer to sections F.
With the stator unit completely detached from the engine it is now possible to remove the
points and condensers.
Points removal
For points removal, disconnect the points wire from the top of the condenser. Then with a
blade screw driver remove the screw, and lock washer retaining the points to the stator
unit. The points should now come free.
Repeat for the other side.
Points installation
Reinstall points in reverse order, ensuring wiring is routed correctly.
Repeat for the other side.
Note:
Prior to removal of the points wire note the correct routing of the wires.
Note:
Silicone can be used to hold wiring in place.
.Condenser removal
To remove the condensers, remove nut and lock washer from top of condenser, remove the
points and ignition wires. Remove the insulating cap. Turn the stator plate upside down on
the bench, so that the condensers are facing down. Support the plate, so that it rests
above the bench. Place a small socket onto the bottom of the condenser, and with a hammer
gently tap. The condenser will now come out.
Condenser Installation:
For condenser installation place the stator unit sideways in a vice. Place a new condenser
into the condenser hole in the stator unit. Place a socket the same size as the outside of
the condenser, on to the top of the condenser. Install a ring of Loctite 242 around base
of condenser Close the vice down on the socket, pressing the condenser into the hole. Make
sure the socket is straight. Stop when the bottom of the condenser is flush with the
bottom of the stator unit. Now install a small quantity of Loctite 242 around bottom of
condenser where contact is made with the stator unit. Repeat for the other side.
Install the insulator caps, wires, washers and nuts.
Caution: A condenser once removed from the stator plate cannot be reused, as the
fit will be to loose for proper ground.
