Techsew 2750-Needle bottoming out, hook still won't reach scarf

[JonesCoLeatherworks]

Hello Friends,

New issue.  I swapped out an #18 needle to a #24 to load thicker thread.  Even though the needles are the same length, I needed to adjust the position of the hook shaft because the hook was running into the needle.  Got the hook to clear and positioned perfectly in the scarf, but now  (see pics) the needle is running past the saddle and causing it to slightly bend.  Does the saddle move perpendicular only or is there an up/down position as well?  Stitch length set to '3'.  Needle is all the way into the needle bar and needle bar is set to 5.5 cm (55mm) from needle bar rocking frame. I look forward to your responses. @Techsew Ron

Show us pic of needle next to hook.  Needle system you are using?   I would say needle bar is fine but hook is off in timing.

For me it looks like the needle bar is set way to low. Are you sure you are using the same needle system / same length needle as before? If so then something is seriously wrong. In the pictures the needle tip is where the feed dog supposed to be mounted. So how does it get there - only reason is a too long needle or a too low set needle bar. Not speaking about the needle hook timing but thats something you should check. I guess you have a proper manual for your machine so the needle hook timing should be mentioned in it.

Here is a JUKI 341 manual (same machine)

Thanks for the response.  This was the position that timed with the hook in the scarf.  After much deliberation, I went below and loosened the bolts on the shaft and somehow it fell into place.  All is working now and perfectly timed.  Weird how sometimes things work out.  I'm not sure what I did, but it was a blessing.
