I was trying to get a parachute harness job done last night.  I went to rethread the machine and like the forgetful old man I am I forgot to thread through the hidden take up lever.  Yes I know, but I haven't had it long, it was 3 am and I'm forgetful.  I actually teach new riggers how to sew so yes I no better. 

So, or course a bunch of thread got bound up around the hook and bobbin. I cut the work loose, opened up the cover, pulled out the loose thread.  Hand wheeled around and the needle was hitting part of the hook.  I was confused and pulled door assembly off and pulled hook out.  Of COURSE, I forgot to tighten the inner race spring lock.  By the time I remembered about the lock I had managed to pull the inner race out from behind the hmm, hook driver?  What ever that part is called.  And now I can't get it back behind to lock it back in place.  I did manage to find the one spring that fell out.  Any help on how to get the inner race back there without complete disassembly?  I got it out but I've tried an hour to get it back.  

Also it seems like the timing is off a lot, like 180 degrees. Do the two halves of the drive shaft under the clamping rings slip around one inside the other?  The timing instructions in English are poorly translated and confusing. Given that I have to retime the bottom anyway maybe releasing the clamp rings and what ever I have to do to get the driver out won't be much more.

Any videos on timing hook?  Couldn't fine any from Uwe or anyone else. 

Help?  Photos in a few minutes.

I just figured out the trick to get the inner race in.  :banana:  I couldn't get it in with the springs in place. But you can with the springs out. Then you can turn the race to match the half circle cut outs in the surrounding structure with the half cir le  cutouts on the race. Insert the spring. A needle helps with line up. Then turn handwheel to allow race to turn and line up another spring. Got all four in, lined up race cutouts for for door assembly bolt, and then pressed in and locked ba k with ser screw. In photo you  an see one spring in and hole lined up for another. 

 

This is the kind of trick that can save hours. And obviously was intended with half cutaways in stationary out side rim. I was trying to figure out why those cutout were tpmhere. That's what led to figuring out how to do it.
