Remove the side lamphouse cover so you can see the shutter and top belt pulley.
Remove the little cover plate with the vents. The round item you see is the governor. This must be removed.
Through the small access hole on the front of the projector, (it may be covered with a chrome piece) use a long, thin screwdriver to loosen the two screws that hold the governor to the shaft. Just loosen them, don't remove them. (These may be rather tight). You will need to turn the governor by hand to see both screws.
Carefully remove the governor from the shaft. There will be several spring loaded brushes behind the governor, do not loose them.
Working from the top, loop the belt over the shuttle pulley and down towards the motor shaft that the governor was attached to.
Use a suitable screwdriver to move the torsion arm and pulley towards the front of the projector.
While holding the torsion arm pulley out of the way with one hand, use the other to place the belt on the motor shaft/pulley. This can be easiest done from the panel hole where the governor was. (It may be easier to have another person hold the screwdriver on the torsion pulley while you work the belt.
Release the torsion pulley so it presses against the belt and confirm the belt is on straight.
Reverse process to assemble, making sure the brushes and springs are properly in place.
