20. Install the ASCD and accelerator control wires on to the intake manifold collector (VG33E only).
21. Check the hydraulic valve lifter.
a.
Push the plunger forcefully with your finger.
●
Be sure to check the hydraulic lifter with the rocker arm is in
the free position (not on the lobe).
b.
If the valve lifter moves more than 1 mm (0.04 in), air may be
inside it.
c.
Bleed the air out by running the engine at 1,000 rpm under no
load for about 10 minutes.
d.
If the hydraulic valve lifters are still noisy, replace them.
e.
Bleed off the air by running the engine at 1,000 rpm under no
load for about 10 minutes. Repeat as necessary to bleed the air
out of the new lifters.
22. Install the remaining components in the reverse order of removal.

Inspection
EBS00GTT
SUPERCHARGER FLANGE
1.
Clean the mating surface of the supercharger flange.
2.
Check the flange surface for any deformation and flatness. Use
a reliable straightedge and feeler gauge, or attach the super-
charger flange to the intake collector mating flange, and check
that the flatness is within specification.
ROTOR SYSTEM
1.
Check that the supercharger pulley rotates smoothly when turning it by hand in a clockwise direction.
Rotating torque must not exceed specification.
2.
Check that both the left and right rotors are free from any cracks or contamination.
SUPERCHARGER BYPASS VALVE ACTUATOR
1.
Apply air pressure of less than 12 kPa (90 mmHg, 3.54 inHg) to
the supercharger bypass valve actuator's lower side hose port
and check for any leakage.
