Friden Calculators (All Jammed)

I have three Friden model SWT calculators, and all have the same problem; they are jammed. Although I have a service crank, and a service manual, the problem still eludes me. I guess I really need to talk to someone who has dealt with this problem before. Maybe I'm wrong, but I think this must be a common problem with these machines, and that they are all suffering from the same ailment. Some guy had a post in one of the archives reporting the same issue. Can anyone help, or point me toward someone who can?
