Jupiter 50 Limited Pitch Bend Range After Bend Pot Replacement

The pitch bender on one of my Jupiter 50’s became erratic after being stored for several months, so I purchase part #3029 and replaced it. However, it now has very little pitch bend range. Is it possible I was sent a log taper instead of a linear taper? Just so I don’t have to pull it apart again to see if that is the problem and have it sit until another part arrives, I was hoping if someone might have experience with this and be able to provide some input.
