8. CHECK PRESSURE READING WITH STEERING
WHEEL TURNED TO FULL LOCK
Be sure the pressure gauge valve is fully opened and the
engine idling.
Minimum pressure: 66 kg/em' (924
psi,
6,374 kPa}
If pressure is low, the gear housing has an internal leak and
must be repaired or replaced.
9. MEASURE STEERING EFFORT

Using a scale, measure the steering effort in both directions.
Maximum steering effort: 4 kg (8.8 lb, 39 N}
If steering effort is excessive, repair the power steering
unit.
NOTE: Be sure to consider tire type, pressure and contact
surface before making your diagnosis.
