Well, it's been about a year since I posted in this forum. Been happily playing away with the projectors I got last year and built up quite a little collection of film from carboots and the sort.

I've just collected a Sankyo 2000 from a freecycle.org member. A neighbour of his was emigrating and left it on top of the dustbin.

It really looks brand new. Been kept in its cover the whole time.

Turned it on and it lit up but there was a "stuck motor" noise and nothing moved.

Took the back off and the drive belt was sitting on its wheels although it was sagging and not at all tight. It was also stuck to the wheels and the reason that the straining noise was being made since the wheels couldn't move.

I've pulled the belt away from the wheels and now when I turn it on the wheels spin around ten to the dozen with no belt to pull.

So it looks like all is well apart from the belt.

I'm just amazed by the belt. It's literally hanging off the wheels and nowhere near tight enough to pull the wheels around.

I think it's fair to say that this machine hasn't been touched for donkeys' years and since it's in such excellent nick I doubt it's worn through a belt in its life so I don't think somebody will have tried to replace it with an incorrect belt.

Can a belt go so saggy just by being sat in the loft?

It's as if it isn't sitting over one of the wheels that it should be sitting over but I can see it covers both wheels, and then some!

Just wondered if anybody had any thoughts before I off to eBay to get a replacement drive belt. Could a wheel be so far out of place that it means the belt is very loose? Looks like there isn't much room for the wheels to move anywhere.

Cheers, all.

Yes, that can happen to rubber so hopefully a new belt is all that is required. Lee's Cameras used to stock just about every belt imaginable so it could be worth looking them up rather than risking something from eBay.

Or you could by a length of this belt material from Dearnn which you cut to length and then melt the ends together.

I have seen a lot of these old belts go saggy like this then eventually decompose into a sticky mess. Good job you found it at this stage because this rubber is really horrid to clean off once it goes sticky. A bit like the ruber round the shutter of some ST1200's
