Distributor vacuum unit - renewal
1 This will normally only be required if a new unit is to be fitted because a fault has been diagnosed in the old one.
2 Remove the distributor cap and the rotor arm. Disconnect the vacuum pipe from the unit.
3 Extract the circlip which holds the vacuum advance actuating rod to the pivot post.
4 Extract the two screws which hold the unit to the distributor body, tilt the unit downwards to release the actuating rod from the pivot post and then withdraw the unit.
5 Fitting is a reversal of removal, but apply a little grease to the pivot post. Fitting may be made easier if the distributor baseplate is rotated slightly with the fingers.
