Caution
l Do not clutch abruptly. l Do not attempt rabbit starts or accelerate quickly.
1. Remove the propeller shaft.
2. Lock the center differential (2WD).
3. Place the front wheets on the roller.
4. Lock the rear wheels and apply the parking brake.
5. Drive the tester roller and check.
6. Upon completion of the test, gradually decelerate with soft
braking and stop the engine.
7. When the test is done, return the differential lclck rod to the
free condition (4WD) and reinstall the propeller shaft.
WHEEL BALANCER (On-the-car Balance)
1.
Jack up all four wheels. Support the wheels to be checked
(front or rear) with the wheel balancer sensor stand and the
remainrng wheels with safety stands.
2. Set the on-the-car balancer. With the center differential in
free condition, drove the tires with the engine; then check.

13EOF3-31 To prevent vaporlock in the fuel system during hot restart idle, a two-stage pressure regulator is adoped
to the new 323 4WD.
Low temperature operation: The vacuum to the pressure regulator (A and B ports) is cut (solenoid valve
[low temp.] UN), and the fuel injection pressure is increased to 284 kPa (2.90 kgf/cm2, 41 psi ) ,
High temperature operation: The vacuum to the pressure regulator (A port) is cut (solenoid valve [high
temp.] ON), and the fuel injection pressure is increased to 343 kPa [ 3.5 kgf/cm2, 49 psi 1.

l All GT-R modek are equpped with the G25MX-R (GSMX-R) manual transaxle and transfer unit.
l The transaxle and transfer unit is the same as in the 323 BP DOt-tC turbo models, except that the speedo-
meter gear ratio is changed.
