Surely they have to be aware of the problem. The sprockets look to be the same as well. The belt is only about 10mm wide. The motor shaft dia is 5mm. I am trying to track down a wider motor drive sprocket with the same teeth and diametre, but would surely void the warranty if i pulled that assembly apart to change the sprocket. I doubt Bintel would want to tackle disassembling the drives, so what is left, a return to Celestron?
Dylan can you have a look at your 'new' mount and see if they fixed the misaligned belt?

just a thought Glen. The belt will run off if the two shafts are not parallel. The worm is held both ends, so it is OK, but it looks like the only things holding the motor in place are the two adjusting screws pulling the motor end plate up against the worm block. If this is the case, any tension on the belt may be sufficient to flex the motor plate and pull the whole motor assembly out of alignment. Maybe back off the belt tension and see if you can tighten the belt by putting finger pressure on the far end of the motor. If you can, it could possibly be worth shimming the front of the motor where it attaches to the end plate or using a zip tie? to stop the far end of the motor from lifting when the belt is tensioned - obviously keeping away from anything that looks delicate.
It sort of looks like maybe they used their spring loaded worm block design ideas from the CGEpro and put it in this mount - however, the original was designed for gears, not a belt under tension???
then again, the above might be rubbish..
