My belt on the main motor is cracked and frayed and has to be changed.Is this a hard job,or should the projector be sent to Leon.

Has anyone here done it before and can guide me in the right direction.Thanks

I've never done a GS, but the ST belts I've changed haven't been that bad. Motor belts have actually been easy (rear spindle belts: a little harder).

I'm about to change a motor pulley on my ST-1200HD and I'd rather change belts any day!

The risk of damage in shipping is kind of scary, it's probably better if you at least give it a go yourself. If you take it easy and gentle, I don't think you can do any harm.

All I ask is a wide screen and a projector to light her by...

Bob, I have found, at least on my two GS1200'S, that there is no need to loosen or disassemble anything to replace the belt. What I have found is that the belt can be pushed off the motor pulley with a little thumb pressure. The belt can then be persuaded off the shutter pulley by carefully pushing on the far side of, it on the inside of the machine, with a small wooden or plastic rod. The belt can then be pulled out carefully between the back side of the shutter and the heat filter arm. There's a bit of a knack to it, and definately a fiddle factor, but I can usually change the belt in about 5 minures this way.
This technique was kind of born out of necessity on my machines since I have found the motor mounting bolts impossible to loosen.

The GS1200 is a wee bit different from the Elmo STs  -

Its easy to change....just slacken the screws "a wee bit" holding the motor, and off comes the belt [Smile] When fitting the new belt do adjust the motor position "up or down" to give you the recommended 5mm slack. Its like adjusting the fan belt on your car...same thing [Smile]

Now there is a lesson for the Bauer T610 Graham!!

A good few hours of a job on these and then a good chance you have totally disturbed the crucial Cam and Claw precise set up!!

90 seconds on a Beaulieu though. [Big Grin] [Wink]
