19. Install the PowerLeash™ control valve and
oil tube between the valve and the rocker
arm shaft making sure the sealing rings are
correctly positioned before tightening the
screws.
If the oil tube is installed incorrectly with the large
end in the control valve and the small end in the
rocker arm shaft, oil leaks will occur. This may
cause oil starvation in the rocker arms which can
result in engine failure.
20. Tighten the control valve screws according
to specification and then connect the wiring
harness to the valve assembly.
21. Adjust the valve and the unit injector rockers.
22. Install the cylinder head cover.
23. Bleed the fuel system.
Flywheel Housing Runout, Check
(Clutch Removed)
CHECKING AXIAL AND RADIAL RUNOUT
1. Clean the flywheel and flywheel housing.
2. Remove the plug from the flywheel housing
and install the appropriate flywheel turning

3. To check axial runout, attach the dial gauge
to the flywheel using the magnetic base and
position its tip against the outer flange
(transmission mounting surface) of the
flywheel housing. Set the dial gauge to zero.
4. Rotate the flywheel and note the indicated
runout at a minimum of four locations around
the outer flange of the housing. Compare the
noted runout with the specified axial runout
tolerance.
