LW 224A Mk V Analyst Projector Drive Belt

[Matthew Dunbar]

Hoping someone can help me. I’m new to film projectors. I’ve got an Athena LW 224A MK V optical data analyzer with a busted belt. I don’t think it is the main belt which is still intact. However, the manual I have only mentions one belt. The broken belt seems to run the sprockets. When I turn the projector off, the lower motor keeps running. If I turn the sprockets by hand it shuts off.
Any ideas what part this is and where I can find another? Thanks in advance

Have you tried CA (super glue)? It can work if the load isn't too high. Otherwise you should be able to find a belting specialist who can match the size and material.
