Centering Sensor Plate & Lever

Check sensor plate for centered position in airflow sensor housing. See Fig 1 . If plate binds on housing or is off-center, remove 6 mm bolt holding plate to lever. Coat bolt with locking compound and install finger tight.
Use Centering Gauge (US 1109) or .004" (.10 mm) feeler gauges to set plate an equal distance from sensor housing. If plate cannot be centered, remove airflow sensor housing.
Turn housing upside-down and remove bolt clamping counterweight to sensor lever. Coat bolt with locking compound and install finger tight. Center sensor plate lever in housing and tighten clamping bolt. Complete centering of plate.
