rotary hook jammed

[George@Printing2Impress]

We've managed to get the rotary hook all jammed up and are unfamiliar with how to free it up and begin putting it all back together correctly. It has spun so that the bobbin case has to be put in upside down to slide into the basket. Make sense? I spent 1/2 hour trying to find a cure on this site, but no luck. Thanks.

Hi George:

As discussed in another thread today.... rotary hook inspection and timing is covered in the "parts and technical manuals" CD you should have gotten with your machine - specifically in the technical manual.

We have the manual out, but the question remains (kind of like the chicken and the egg). Did the rotary hook go upside down because it spun on a spindle as it became jammed (which I think means we would have to clear all the clogged thread somehow before we can work on checking timing), or do we just go straight to checking the timing with the clogged thread in it and it will somehow free up everything so we can clear it?

It sounds as if the rotary hook has actually been shifted on the shaft ti where it is seriously out of time.

It also sounds as if you need to completely remove the rotary hook, clean out the mess and then reinstall it using the information found on rotary hook timing procedures in the CD tech manual. The procedure must be followed exactly as the tolerances in this setting is critical to the operation of the machine.

Rod - That is exactly where we had to go, and we did remove & clean. After a few hours we thought we were there with the timing, brought a needle down (thinking this would be it) and it was again outside of (bent forward) and a well off the elongated hole of the rotary hook that we had so carefully lined up after setting the closest needle and to correct 199.8 degrees a couple of times. Gave up and went to bed. Will try giving tech support a call to walk us through it, or see if a local tech can come over and show us the right way. thx.
