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.
