I was recently given a Sankyo 2000 by someone who told me it would need a new drive belt so I was delighted to find online an excellent guide to refitting one and the extra help and enthusiasm from this forum. When I opened it up, I was surprised to find that the old belt was flat, not round section like the ones I could buy and the one in Janice's video. I assume that I will be able to replace with a round one? Actually, both belts appear to be working, though, of course, I don't know if they are working well enough. The biggest problem seems to be that when I feed the tape in, no obvious sprocket grasps it and feeds it through as I had expected from previous super 8 projectors I had owned many years ago. Can anyone help please?
You won`t feel that because these projectors are sprockless. The film is pulled through by the rubber rollers you feed the film into the projector through.

That is most helpful, thank you. I am guessing therefore that the reason the film isn't passing through is lack of belt tension so a new belt should help, I hope

Do you have a manual for the projector? In order for it to auto thread, the control must be turned to the forward position (not all the way to the lamp on position). When you turn the control on, you should see the upper loop setter click down. Then feed the film and it should be grabbed by the rollers. Yes, round belts are frequently used to replace the old flat ones. They work fine.

Welcome to the forum David. If after changing the belt you still find the film not feeding you should look for a couple things. Remove the cover and with some test film or leader...turn on the projector to the forward position and feed the film. Watch if it is picked up by the front feeder roller and fed into the gate. If not, then the feed roller might be damaged.
If the film makes it through the feeder roller down to the gate then stops...then the claw (small wire-like pin that enters the film sprocket holes to advance each frame through the gate) might either be broken or needs adjustment.
