unit is fitted to the distributor, care must be taken not to twist the unit
when removing lead.

on engine. On cars bearing chassis number prior to R 3061 the exhaust
pipe is coupled to the silencer by means of a flange and four studs, and the
front end of the pipe is located in the exhaust elbow on the engine by a set
screw. On cars bearing chassis number R 3061 and onwards, the exhaust
pipe is coupled to the silencer by a clip and clamping bolt, and the front
end is bolted to the flanged end of the exhaust elbow. It will facilitate
dismantling if the exhaust pipe is not removed from the manifold elbow
