Timing belts change at Mitsubishi / Hyundai

Hi, I still have a little special question, recently I tried to change the timing belt of my Hyundai Pony… Engine: Year of construction 93, replica of Mitsubishi Colt, 1.5l, 83PS, GLSi, ECI-Multi (Type No. 8252,313) … everything worked quite well up to a certain point, the Servo Punpe..Lichtmschine etc. folded away, the wedge belt removed…and the upper part of the two-part cover could also be easily removed…so far… …but from there it didn’t go any further. ..in order to remove the lower cover I would have had to remove either the pulley of the water pump or that of the crankshaft…(which I did not manage) …if any of you had experience with this type of engine and subject, it would be awesome if you could tell me which disc and how to remove it… Thanks in advance 🙂
