I used the Röhm Supra 871050 - and, yes, the old chuck wasn't the easiest thing to remove, I fitted a large hex key in the chuck (small end of the 'L' in the chuck) and then a steel tube over the other end for leverage. A couple of taps on the pipe with a hammer plus a lot of sweat and it eventually started to undo.Which Rohm Supra chuck did you get.l have a Bosch PD40 and was thinking of replacing the chuck.Did you have much difficulty getting the original chuck off.
