Turn engine with engine cranking device until the
piston in the cylinder to be set is at TDC (Top Dead
Centre). At this point both inlet and exhaust valves
will be open i. e. valves overlap.
Note:
As far as possible turn engine only in di-
rection 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.
