Removal and installation

PERFORMANCE ORDER
1. To disconnect blocks.
2. To turn off a bolt and to remove an arm with sensors.
3. To remove transmission to get access to an engine flywheel.
4. To turn a cranked shaft so that the pin on a flywheel appeared in cut under the sensor.
5. To establish an arm with the sensor on a place and the probe to measure a gap between a pin of a flywheel and the sensor of a corner of an advancing of ignition and a gap between the sensor of frequency of rotation of a cranked shaft and a flywheel.
6. The gap between a pin and the sensor of a corner of an advancing of ignition has to be 0,45–1,25 mm, and between a flywheel and the sensor of frequency of rotation – 0,51–1,24 mm.
7. If the measured gaps differ from specified, to replace an arm of sensors. It is also possible to enclose laying for increase in gaps or to proshlifovat an arm for their reduction.
