In the above charts, with the intake and exhaust
valves of No. 6 cylinder overlapped, adjust the
valve clearance marked " " and then turn the
crank shaft by 360 to adjust the valve clear-
ance marked " ".

Valve overlapping state

*
This is a state where intake valve starts
opening before exhaust valve is completely
closed at the end of exhaust stroke, and
accordingly the intake and exhaust valves
of the same cylinder are working.

(5) Adjustment of valve clearance(for DDC engine)

1. Bar the engine over until one of the fuel injec-
tors just starts in downward stroke.
Caution
Never set the valves and injector of the same cylin-
der at the same time. Doing this will result in en-
gine damage.
2. Adjust all valves(two intake, two exhaust) at this
cylinder position and set the fuel injector height
on the companion cylinder, which is shown on
the Timing Circle Chart in Figure MTC0251.
3. Bar the engine over in clockwise position until
the fuel injector for the next cylinder shown in
the Timing Circle Chart Figure MTC0251 just
begins its downward stroke.
4. Adjust the valves for this cylinder, and set the
fuel injector height for the companion
cylinder(shown in parentheses) on the Timing
Circle Chart Figure MTC0251.
5. Continue around the clock until all six fuel in-
jectors and sets of valves have been adjusted.
