Where can I buy worm gear for Bell & Howell 535 16mm projector?

Juan Camilo González · November 16

Hi, I am new here so hoping I am posting in the right place.

I am in Bogotá, Colombia and recently got a Bell & Howell 535 projector, its hard to find any working 16mm projectors around here. It worked fine for a bit but then it stopped working.

I opened it and found the plastic worm gear broken inside (pictures attached). I am hoping to fix it and need some help.

Mainly, I would like to get recommendations for where to buy a replacement online that can ship to Colombia. Found a couple on ebay but not sure if they are the right ones:

Also, since I am taking it apart, I am thinking I should do a deep clean and perhaps replace any other part that I should in the process. I don't know much about fixing this machine but willing to invest the time so I can bring it back to life. So far, my plan is to replace the worm gear but since I am ordering this, I should also try to get any other parts I need in the same order. Should I get belts or anything else?

Any advice from any of you that have done this before is greatly appreciated.

Thanks,

Juan
