Review on Bell Howell Cube Projector Drive by Michael Powell

When my Bell and Howell slide projector started to fail I found the prime mover was the culprit. It requires quite a bit of disassembly to access and remove the worn gear. So keep an eye on what you remove and where it goes. My online search for a Revain replacement part was quick and easy and the new part worked great. One more thing, you'll need to adjust the meshing between this gear and the gear teeth on the carriage's carrier so that there is no binding, but this is easy. Glad to know there are still parts for this year's projector!
