Removal
All engines except TU series 1 Disconnect the battery negative lead.

2 Remove the air cleaner and/or inlet duct, as necessary for access, with reference to the relevant Part of Chapter 4.

3 Identify the HT leads for position then disconnect them from the spark plugs.

4 Slide off the ignition coil cover and disconnect the HT lead from the coil.

5 Pull back the plastic cover then unclip and remove the distributor cap (see illustration).

4.5 Pull back the plastic cover then unclip and remove the distributor cap

Note that on certain later models the cap is retained by two screws instead of clips.

6 Disconnect the wiring at the connector, where necessary pulling out the spring clip first.

7 Pull the hose from the vacuum advance unit.

8 Mark the distributor mounting flange in relation to the cylinder head or thermostat housing as applicable.

9 Unscrew the mounting nuts, remove the small plates, and withdraw the distributor (see illustrations).

4.9a On non-TU series engines, unscrew the mounting nuts . . .

4.9b . . . and remove the distributor

10 Check the condition of the O-ring on the mounting flange and renew it if necessary.

TU series engines
11 Remove the ignition HT coil (Section 3).

12 Identify the HT leads for position, then disconnect them from the spark plugs.

13 Unbolt the HT lead support from the cylinder head.

14 Pull back the plastic cover, then extract the screws and remove the distributor cap.

15 Disconnect the wiring at the connector (see illustration).

4.15 Disconnect the distributor wiring connector on TU series engines

16 Pull the hose from the vacuum advance unit.

17 Mark the distributor mounting flange in relation to the distributor/fuel pump housing (see illustration).

4.17 Mark the distributor and housing . . .

18 Unscrew the mounting nuts, remove the small plates, and withdraw the distributor (see illustration).

4.18 . . . then remove the distributor

19 Check the condition of the O-ring on the mounting flange, and renew it if necessary.

Refitting
All engines
20 Refitting is a reversal of removal, but turn the rotor arm as required to align the lugs with the offset slot in the camshaft. If the old distributor is being refitted, align the previously made marks before tightening the mounting nuts. If fitting a new distributor, initially set the distributor in the middle of the slotted holes or follow the procedure given in Section 8, then finally adjust the ignition timing (Section 8).
