Use barring device to turn engine so that the pis-
ton in the cylinder to be set is at TDC and the two
valves are closed. At this point both inlet and ex-
haust valves will be open i.e. valves overlap.
Note:
As far as possible turn engine only in direc-
tion of rotation (anti-clockwise as seen when
looking at the flywheel) in order to prevent
the direction of rotation of the raw water
pump impeller being reversed.
