How to remove and refit the distributor on EZL and TSZ ignition systems on Mercedes-Benz 190E?

EZL ignition models use the sensor crankshaft position as a trigger, the distributor only passes a high tension voltage to the spark plugs, and the ignition timing can not be adjusted by turning the distributor body. The distributor may be removed by first disconnecting the battery negative lead and then loosening the screws to remove the distributor cap. Bring No 1 piston to top dead center (TDC) retain good position in the case of removing and refitting. Once the clamp bolt has been loosened, remove the distributor body off of the crankcase and examine the O-Ring oil seal whether you see evidence of wear or leakage. In refitting: to refit, when not rotated all the way through TDC but with the rotor arm aligned to the alignment marking and the clamp bolt hole aligned to the long slot, insert distributor into the crank case. Insert clamp bolt after which the screws and the screwdriver should be substituted with the distributor hose end. Models utilizing TSZ ignitions are activated, in contrast, by a sensor within the distributor and the ignition timing retests and corrections are necessary during removal. The removal can be carried out in the same manner with the following initial steps, de-connection of vacuum unit hose and sensor wiring, marking of alignment of the distributor to be refitted. Once the distributor has been removed out of the crankcase with the O-ring seal, the refitting procedure is the same, except there is an additional step to fix the vacuum unit hose and sensor wiring back and to verify and reset ignition timing as required.
