Hi. I'm looking for some information for an Elmo Gs 1200.The issue I'm having is with the feed and take up reels wont turn or turn slow with reels on them.The belts are not slipping and I can see that the motors are running.It looks like the small spur gear is slipping or not completely engaged.Any information would be appreciated. Thanks T.Fiedler

Is this a projector you have used and worked correctly, but now is malfunctioning? It could one of several things.
Which gear are you referring to as the spur gear? Could you take the back cover off and post some photos of the inside? These ST-1200s are pretty easy to maintain.

Big fat correction: The link to the belt set below is for an ST-1200. :oops:

The problem with your GS-1200 is not belts. I have experienced this slow down before. The solution is to clean contacts on a circuit board. It's been 5 years or more since I did this , so I will have to search my brain and get back to you.

Five years is along time for Mr. Elmo. Time for a tune up. I would replace the motor drive belts and the forward/rewind belt and lube the nylon gears with white lithium grease to start with. You can buy the grease at a hardware store.

I usually buy belts from this Ebayer:

I just bought a couple of sets today!

Just a quick update to what Dan is going to talk about. I recieved my first ST1200 a year ago after it had been in a storage locker for years. The belts on mine were goo and I had to clean and replace every one of them. Working with electronics in the past I knew the contact points on the non-soldered wiring may be a problem. Take the back cover off and look for corrosion on any contact points where you can pull the wires off. I call them friction points or knife contacts. Do this one wire and one point at a time so you don't confuse wires. There aren't many of them on this machine so it shouldn't take long. Any connections where the copper looks dark needs to be cleaned. The best way to do this is with a simple pencil eraser. Rub the contact until it shines and reinstall the wire. Just to be sure, take the contact back off and reinstall it again several times to scrape off corrosion. Most of the contact points you can only clean one side of them but that is enough to get it back to working order. It took me about an hour to clean every one but it has been well worth it.
One thing to keep in mind though is that Dan was right before, try to clean off the old grease and relube every gear you can see with new lithium grease. It is much easier on the plastic gears.

Erik, great advice for the ST-1200, but I think I really confused readers with my above mistake. The post is about a GS-1200.

Now I am confused. In all my time collecting I've never heard of a GS1200. How far removed is that from an ST 1200 unit?

Thanks for the information I will give it a try this weekend. The only thing that concerns me is that the motor is turning at the corect speed but one of the gears slips on the shaft when the film reels are on.
