Bell & Howell Filmosound 655 16mm Projector
Hello, i have a problem with my projector, the plastic worm drive is split, preventing the correct operation of the machine, i have no experience of the repair of these projectors, i have electronic/mechanical knowledge, could someone point me in the right direction regarding repair and where i could possibly find a replacement worm drive?

Hi Crusher,
if the broken part is not readily available, could 3d Printing help? Often these can reproduce complex shapes. You may have a local service offering this. Good Luck - Mike |

I should think there would be plenty of other B & H spare places. |

Re: Bell & Howell Filmosound 655 16mm Projector
Several on eBay, search 'bell howell worm'. If your projector has still picture 'animation' and you want to preserve this functionality you'll need the 'animation' type.
Be warned changing the worm is a big job, it's at the heart of the mechanism and I don't think B&H expected it to be done. The originals seem to split because they are a nylon style material moulded over aluminium. Over time differential expansion cracks the plastic. |

Re: Bell & Howell Filmosound 655 16mm Projector
I’ve done a couple of those and it is a very messy job because of the grease that will need to be cleaned off. Just make sure all the parts are fitted exactly in the correct sequence and position or it won’t run. When completed wind the mech by hand to make sure it’s good before applying power.
