Ignition distributor (injector 1.8 and 2.0 l) — removal, repair and installation (Opel Astra F)

Single camshaft engine

The distributor consists only of a cover, a rotating cam and a plastic screen installed on the end of the camshaft housing.

Removal

The order of execution of works as indicated in the first two points of this section.

Using a Top socket wrench, remove the three bolts and separate the distributor cap (together with high voltage wires) from the distributor (Fig. 5.11).



Remove the plastic shield from the cam body. The shield is installed using a sealing ring located in a groove around the periphery. Loosen its fixation, being careful not to damage the cam itself.

Using a socket wrench, remove the two bolts and remove the rotating cam, leaving the metal rotor sleeve in the housing (Fig. 5.12).

Repair

Visually inspect the distributor cap and rotating cam as described previously.

Installation

Check the sealing ring on the plastic screen and replace it if necessary.

Installation is carried out in the reverse order of removal. Note, however, that the rotating cam can only be installed in one position. If necessary, turn its sleeve so that the screw holes coincide with the holes in the rotating cam and the end of the camshaft. Check that the high voltage wires are connected correctly.

Twin Cam Engine

Removal

Disconnect the negative battery terminal.

Remove the screws and lift the spark plug cover off the camshaft cover, then disconnect the high voltage wires from the spark plugs and release the wires from the clamp at the bracket located on the end face of the camshaft cover. Disconnect the high voltage wire from the coil. Note the location of the wires for subsequent installation.

Using a Torx socket wrench, remove the three bolts and the distributor cap (together with high voltage wires) from the distributor.

Disconnect the distributor plug.

Unscrew the two bolts securing the distributor to the cylinder head and remove the distributor. Note that the offset pin on the distributor drive engages with the corresponding hole in the end of the camshaft (fig. 5.13 and 5.14).

Repair

There are no parts available for the distributor and if it fails it must be replaced entirely. The distributor cap and rotating cam can be visually inspected as described above in this section.
