Resetting the dial indicator

Components:
6
1 Dial indicator
2 Support for dial indicator
3 Camshaft sensor support surface control gauge
4
measurement: 30,24 ÷ 30,26 mm
4 Resetting master measure: 30,24 ÷ 30,26 mm for gauge
5 Resetting reference base
If replacing the sensor, camshaft or engine block via the tool see figu-
5
re 56.
Make sure that the support surface of the sensor on the camshaft
support measures 30,24 ÷ 30,26 mm. Assemble the dial indicator 1
in the support 2. Insert the support 2 complete with dial indicator 1
into the gauge 3. Set the master 4 and reset the dial indicator while
resting on the base 5 as in 6.
Measuring the depth between the sensor support and the
camshaft
Insert the gauge complete with dial indicator onto the sensor support
and attach using the three screws.
Make sure the measurements taken are within the specific tolerance
limits 30.24 ÷ 30.26 mm.
The three screws for the phase sensor support screws must be

tightened to 8 Nm using a torque wrench.

Air gap adjustment

The air gap is adjusted using shims measuring 0,2 mm in thickness
which are placed between the sensor surface and its support.
The air gap must be between 0,3 and 0,5 mm (see phase sensor as-
sembly diagram page 94).
When adjusting the air gap with shims, it is important to consider any
difference between the measurements taken (length of the sensor pin
and depth between the sensor support surface and the camshaft) and
specifications.
Example of where to insert the air gap adjustment shims.
