The roller of the sensor-distributor of the ignition is connected to the camshaft shank in only one position. Therefore, before installation, turn the shaft of the sensor-distributor in such a position that the cams of the shaft coupling are against the grooves of the camshaft.
Put a sealing ring on the flange of the sensor-distributor. Install the distributor sensor on the auxiliary unit housing in such a position that the middle division on the distributor sensor flange is against the mounting ledge on the auxiliary unit housing (see fig. 34). Install the high voltage wire bracket. Fix the bracket and the sensor-distributor with nuts. Connect wires and a vacuum hose to the sensor-distributor, and then check and, if necessary, adjust the ignition timing.
To replace any parts, disassembly is carried out in the following order. Remove cover 8 (pic. 143), rotor 9 and protective screen 10. Disconnect the vacuum regulator rod 3 from the base plate 6 of the sensor, unscrew the fastening screws and remove the vacuum regulator. The fastening screws are unscrewed and the base plate 6 is assembled with the sensor 5 and the holder 7: Remove the spring from the clutch 1, remove the pin and remove the clutch and adjusting washers from the shaft. Take out from the body 2 roller with centrifugal regulator 4 and washers.
Assembly is performed in the reverse order of disassembly. When assembling, it is necessary to select shims to ensure the axial free play of the roller is not more than 0.35 mm.
