I need instructions for replacing the Tilton S5A drive belt on a GAF 688 Anscovision projector. No owner's manual or any other paperwork came with this used machine. Any good tips or tricks would be helpful. Thanks, Lynn

Question edited for clarity, full 'make model (what it is)'.

check the belts

not a car moved yah to 35mm projectors
no GAF here so picked wrong one.
google the manual>?

I am definitely not an expert about these but having seem them in operation I believe the rear wheel is or should be powered.

The examples I have seen used a slipping belt method that provides enough drive to the takeup spool to wind on the film without any significant tension on the film.
The belts looked as though they were made from something like curtain wire...

check the manual. some do not remove, they just fold away, but there is a spring catch to release it.

1. • 1Find out the driver belt's part number. This can be found in your lawn mower's owner manual.

   • 3Clean out the underside of your mower's deck, making sure there are no leftover pieces from your old belt still stuck inside.
     
   • 4Find your mower's tensioner, which keeps the pulleys in place, and loosen it (this usually involves loosening a single bolt). Then slide the pulleys closer together so that you can fit the belt over them more easily.
     
   • 5Arrange the driver belt over the pulleys (you should refer to your user manual for the exact configuration of the belt over the pulleys, since this will vary depending on the specific model of your lawn mower).
     
   • 6Tighten the tensioner back up, leaving only about a finger's width left of play in the belt.
