Contact Breaker
IGNITION
A LUCAS type K2F magneto is fitted. The replacement part number is 42230-A and
the part number of the complete contact breaker is 492854.
Lubrication and adjustment is required every 3,000 miles, cleaning is required every
5,000 miles and every 10,000 miles the complete unit should be handed to a Lucas
Service Station for dismantling, replacement of worn parts, cleaning and lubrication.
Lubrication every 3,000 miles.
(a) The cam is supplied with lubricant from a felt pad contained in a pocket in the
contact breaker housing. A small hole in the cam fitted with a wick, enables the oil to
find its way on to the surface of the cam. Remove the contact breaker cover and turn
over the engine until the hole in the cam can be clearly seen and then carefully add a
few drops of thin machine oil. (The hole is located in the lowermost part of the cam
ring). Do not allow any oil to get on the contact points.
