1595Ford Fiesta Remake5B•6 Ignition system7.4a Disconnecting the distributor multiplugand separate the suppressor shield from thecap (see illustrations).5 Withdraw the rotor arm from the distributorshaft.6 Before refitting, wipe clean the distributorcap and leads and carry out a carefulinspection as described in Chapter 1.Refitting7 Refitting is a reversal of the removalprocedure, ensuring that the HT leads aresecurely connected and in the correct order.8 Distributor -removal and refitting2Note: On pre-September 1990 CVH engineswith CFi fuel injection, unless the originaldistributor is to be refitted to the originalcylinder head, it will be necessary to take thevehicle to a Ford dealer for accurateadjustment of the ignition timing after refitting.Removal1 Disconnect the battery negative (earth) lead(refer to Part A, Section 1).2 If the original distributor is to be refitted tothe original cylinder head, check that thepunch marks on the cylinder head anddistributor body are aligned before removingthe distributor (see illustration). If no marksare present, make your own using a punch or7.4b Releasing one of the distributor capsecuring clips by carefully levering with ascrewdriversmall file to ensure correct alignment uponsubsequent refitting.3 Refer to Section 7 and remove thedistributor cap.4 On carburettor equipped CVH engines,disconnect the vacuum pipe from thedistributor vacuum diaphragm unit.5 Disconnect the wiring multi-plug from thedistributor.6 Remove the clamp bolts securing thedistributor in position and slide it out (seeillustration).7 Prior to refitting, check the condition of thedistributor oil seal and renew it if necessary.RefittingCVH engines with carburettor8 Position the distributor so that its offsetdrive is engaged with the slot in the end of thecamshaft, then loosely insert the two clampbolts.9 Where both original punch marks arepresent, on the cylinder head and distributorbody, rotate the distributor body until thepunch marks are aligned before fullytightening the clamp bolts.10 If one or both of the punch marks aremissing (due to component renewal), turn thebody of the distributor so that the clamp boltsare centrally located in their slots then fullytighten the bolts.11 Refit the rotor arm (if removed), distributorcap, suppressor shield (as applicable) and HT7.4c Withdrawing the distributor cap andsuppressor shield assemblyleads, making reference to Section 7, thenreconnect the wiring multi-plug and vacuumpipe.12 Reconnect the battery negative lead.13 If one or both of the punch marks aremissing after component renewal, check theignition timing, as described in Section 10,and adjust as necessary. This will not berequired where the original punch marks havebeen re-aligned.Pre-September 1990 CVH engineswith CFi fuel injection14 Position the distributor so that its offsetdrive is engaged with the slot in the end of thecamshaft, then loosely insert the two clampbolts.15 Where both original punch marks arepresent, on the cylinder head and distributorbody, rotate the distributor body until thepunch marks are aligned then fully tighten theclamp bolts.16 If one or both of the punch marks aremissing (due to component renewal), rotatethe distributor body until the centre linethrough the distributor multi-plug connector isat 40° to the vertical (see illustration), beforefully tightening the distributor clamp bolts.This will give an approximate (static) ignitiontiming setting to enable starting of the engine8.2 Distributor alignment punch marks(arrowed)8.6 Removing the distributor from thecylinder head8.16 Distributor orientation when re-fittingif alignment punch marks are missing (Pre-September 1990 CVH engines with CFi fuelinjection)A Direction of rotationB Centre line through distributor connector(40º to vertical)
