Rotate the camshaft by turning the central nut in an
anti-clockwise direction to bring piston N° 1 of the
engine to the Top Dead Centre position (T.D.C.) when
the piston is at its uppermost part of the compression
stroke.
Check the timing of the engine by ensuring that the inci-
sion stamped on tooth A of the timing wheel is in line
with the “tooth” B that is present on the engine casing.
The following photograph illustrates clearly the correct
position.
A
The position of the timing wheel is clearly seen in the
enlargement in respect of the mark on the engine cas-
ing. Also the marks present on the toothed wheels of
the camshaft must be aligned together when the timing
wheel is in this position.
