REPAIR INSTRUCTIONS, PART 3
ENGINE SETUP AND
ADJUSTMENTS
Fuel Injection Timing
There is no need to set injection pump-to-engine
timing. Unit pump-to-engine timing is
programmed into and controlled by the EECU.
However, the flywheel still has pump timing
marks to accommodate application to non-current
engines.
Valve Adjustment
[213 NB]
Do not remove the EGR MASS Flow sensors
from the cool tube to allow access to the cylinder
head covers (if so equipped). Remove the EGR
cool tube as an assembly to access the cylinder
head covers and upper valve train components.
LOCATING AND MARKING FLYWHEEL
VALVE ADJUSTMENT MARKINGS
Some engines may be equipped with flywheels
that have missing or illegible valve adjustment
markings. If this problem is encountered, a typical
flywheel can be marked while the engine is in the
chassis.
TYPICAL FLYWHEELS
On a typical flywheel, the top center (TC)
markings, and the valve adjustment markings,
are directly in line with the clutch mounting
bolt/bolt holes. To determine if the engine is
equipped with a typical flywheel, view the
flywheel through the timing access hole in the
flywheel housing. Align the TC markings with the
timing pointer. If the flywheel is typical, there
should be a clutch mounting bolt/bolt hole directly
in line with the TC marking. In this case, the valve
adjustment markings should be in line with a
clutch mounting bolt at three locations. Refer to
Figure 539.
