Hi, I am working on a 340020 Hermle (this one marked Bulova ) movement. I removed the mainsprings from the three barrels for cleaning. There are three and these are the type that the arbor just pulls out and you can remove them from the movement while the movement is still together. The spindles are inside the barrel. I was careful to not mix the three up keeping them separate. I greased the springs, put them back into the barrels ok and two of the the large one and one small one are ok but one I cannot get the cap on because the spindle prevents it from going down all the way. I know it's not backwards because the spindle can only go in one way in order to turn the spring properly. What am I missing? I've done this procedure many times (not hundreds mind you) but I'm lost today. Any suggestions/observations would be appreciated. I am aware also that the two smaller sized spindles are different in that the shoulders are different but I tried interchanging them and I still can't reinstall properly?
