Exploring Large Format

Hello Sinar experts!
I mounted and adjusted my chrome Auto Aperture cable onto my Norma 4x5 back according to instructions I found in a manual, and the green Norma-era shutter closes fully when I insert the film holder. However, when I remove the holder, the shutter reopens slowly, and even then sometimes only partially.
I'm guessing this is because of an old spring in the shutter that is no longer able to return that cable plunger back, and that the only solution is a CLA. Does that sound about right?
Also, there isn't any lubrication of the cable and/or the slide within the film holder/back that might help, is there?
Thanks!
