Has anyone here ever replaced the motor belt on a Elmo HiVision SC-18? I bought a like new unit but the belt isn't there. The inside is so compact, I wouldn't even know where to start disassembly. I can send it out for a repair, but it will cost me more than what I paid for it.

Hello Joe,

The Elmo SC-18 needs two belts, one to rotate the spindles and the other for the shutter (motor belt).

The pictures below should help you install both belts on you SC-18 projector. You need to remove the back (be careful with the sound cord connection). You also need to remove the flywheel to install the motor belt (picture number one shows the flywheel before being removed)

That's it!

Don't forget to install the flywheel and re-connect the sound cord.

I hope this helps.

Jon

Very helpful but the motor shaft extends far across (where it was behind the flywheel). How do I get the belt over the shaft? Does the white nylon slide back and forth on the shaft to make the tiny space shown in the last picture? Does the speed need to be adjusted after belt installation?

Yes, the white nylon shaft slides back, you can see it closed in picture number 3 and opened in the last picture.

The speed may may or may not run slightly faster when the belts are installed but very little to make any difference, the speed will settle after running a couple of 400 footers - If you find the need to adjust the speeds, the pots are located on the small board top left.

Thanks for the information; replacement belts have been ordered. I will install them later this coming week. This help is saving me around $200! [Big Grin]

Not really Joe, let me know how much you really saved, if anything, once you get my bill [Big Grin] [Big Grin] [Big Grin]

Enjoy.

After quite a bit of fiddling I installed the motor belt. The projector works well. No speed adjustment was necessary. [Big Grin]

Hello Joe,

I'm happy you got the job done and gained a bit of experience by it. Rest assured it will be a lot easier the next time you have to change the belts. [Wink]

Don't worry about my bill, I took an income tax deduction for it. [Big Grin] [Big Grin]

Jon, Frustration is a better word for experience. The very narrow space next to the shutter pulley was a bit smaller than the belt thickness. I used a wooden craft stick shaped like a tongue depressor to push the belt through the space. I didn't dare use anything metal to push the belt with. I was going to change the rewind belt too, but I quit while I was ahead since that belt is intact.

Hello Joe,have you considered the belting that can be heat joined
this might save some "aggro" and bad language in the future.
Just a thought.

Hugh,I'm aware of the belting but have never tried it. I don't trust that the weld would hold. Since the motor belt was nowhere in sight, I wouldn't have known the size to fabricate.

I just got my new belts for this projector today. I have installed the top belt, removed the flywheel, but there's no way to get a belt even if I move the white plastic thingy all the way left. Do I need to remove the screws there?

With the white plastic coupling removed this appears a very simple belt change Vidar.

Whereabouts are you struggling at the drive end or the shutter end?

try to remove the white plastic coupling altogether, or at least manoeuvre it right out of your way as the image above shows while you are fitting belt if it is the drive end you are struggling with.

I can't get the white plastic thingy moved long enough left to open up the space. Do I need to remove the spring on the white plastic?

I cannot see for sure from the photograph Vidar, what that spring is holding in place but it must be helping the plastic coupling or thingy as you call it, from allowing the white plastic coupling to slide up and down the shaft. I would say from just from what I can make out from the photo, that the spring is a retaining spring and beneath it are perhaps two split halves of plastic or metal that locate the whole thing in position on the shaft.

Try to remove the spring Vidar and see what's beneath.

Vidar, the white plastic shaft coupler should move a few millimeters, just enough to slide the new belt in. The spring assay is what's keeping the shaft connected to the motor. Here's another set of pics I took for a tutorial posted on this forum a while ago : go to this page.

Was a locking piece to the left of the spring that I can't see in your pictures. The spring wasn't really removable. All done and it runs fine now :-) Thanks

Lovely little machine
