- A. clutch replacement (after replacing only the clutch disc, the sensor does not need to be adjusted)
- b. clutch housing replacement
- V. changing the relative position of the sensor and its support bracket
- d. if the ignition timing control using the diagnostic socket gives incorrect results.
2. To remove the sensor v.m.t. Unscrew the hex head bolt securing the support bracket to the clutch housing and remove the sensor together with the bracket. Do not touch the Phillips screw on the bracket. When following this procedure, and if none of the above operations were performed, it is not necessary to adjust the air gap between the sensor and the clutch disc.
3. To remove the sensor from the bracket, unscrew the crosshead clamping screw and pull out the sensor. After that, it will be necessary to adjust the air gap.
4. Installation of the sensor and its regulation are carried out as follows. Mount the sensor on the bracket without fully tightening the clamping cross screw yet. Check that the notch on the clutch is not aligned with the hole in the crankcase for installing the sensor - if they are aligned, turn the crankshaft a little with a wrench thrown over its pulley bolt. Secure the bracket with the bolt to the clutch housing and carefully press the sensor until it touches the clutch. Tighten the Phillips screw and then unscrew the bolt and remove the bracket together with the sensor from the clutch housing. Mark the position of the sensor on the bracket, loosen the clamping Phillips screw and carefully pull the sensor 1 mm from its marked position. Tighten the clamping screw again. Install the bracket with the transmitter on the clutch housing and tighten the fixing bolt. There should now be a gap of 1 mm between the end of the sensor and the clutch (see b/fig. 4.13).
5. When installing a new transducer that has not been used before, follow the above instructions until the Phillips screw is tightened, but it is not necessary to remove the bolt and remove the bracket with the transducer. After tightening the cross screw, the clearance adjustment can be considered complete, because. The new sensors are designed for this simplified installation.
