instructions on how to replace the belt on a dejur 750 movie projector?

I sympathize with you. I have done it. As you probably realize, it was very difficult. I had to figure it out all on my own. I don't know how to describe to you what I did. If you do attempt it, set aside hours of free time with no distractions. Write down each and every thing you do in the order that you do it. Finally, be very careful. One mistake can mess up everything. I hope I haven't frightened you. It can be done.
