29K15

[Simes]

I wonder if someone can help?  

How do you get the Shuttle Carrier off the gear underneath? I can see a tiny hole in the pinon, but I don't know what to do?  It doesn't look like there is a screw in it.  Thinking of giving it a tap with a pin and a hammer.

Call siserve & ask Peter. If you don't know, don't play

For a 29K15 I can't be certain it may be pinned, later models have tapered screws but you would see this. Parts aren't necessarily interchangeable between the 15 and later numbers as they are different design the pin and hammer idea is probably the way to try but remember the timing if you do get it apart.

Thanks Peter,  It's running much better now.  It's had a good clean but this is the last piece we need to check.  For some reason the top thread get's caught underneath the shuttle carrier which seems to be a tension issue.  We have to keep tightening the tension each time we use the machine.

Thats a different issue, 2 things you can try shortening the needle a little or experiment by dropping it a little as length matters  

More commonly I have found the shuttle carrier wears, if you are brave enough you can get a punch and tap the leading edge of the carrier down to reduce the gap between it and the arm, another option if you manage to get it off is to put a shim there if you can get one the right size
