Thread: MC1100 speed selector has dis-connected from pulleys. How to fix ?

The speed selector on my 6 year old MC1100 (carbatec) has dropped a grub screw and has disconnected from the pulley system. At least I think that's what happened.

No loud sharp noises just a freely moving handle when disengaged to change speeds. When I removed the headstock cowling I found a 25x8mm grub screw sitting in the housing base. It's hard to tell without mirrors and lights or standing on my head but I can feel a hole in the bottom of a casing on the right hand side of the headstock pulley. Presumably it fits here, locking the speed selector handle mechanism to the pulley/belt system. As far as I can tell using fingertips, everything in the handle system moves correctly when I change speed setting.

Before I start playing with things I can't easily see, some advice would be handy. I'm sure I'm not the first person to have this occur. So - some questions.
1) Is this the right place and is inserting the grubscrew pretty much all I need to do to correctly fix this immediate issue ?
(Assuming I know the correct position for the handle - think I do.)

2) If the handle is engaged in the wrong position - will subsequently setting a higher (highest) or lower (lowest) speed damage the pulleys ? If so can you suggest a safe method to determine the correct position ?

3) Any other advice ? (To fix the speed selector - no MC900/1100 jibes, I've heard them before.)

Thanks in advance and over to you.
