Tension Release Lever Rod

[Teslabolt]

I am having a myriad of issues threading my new to me used Consew 206RB-1 - the Lower thread is very loose. See pics. 

Watching other videos on how to thread the machine, there is one where the YouTuber states that when the foot lever is up, it will release the tension on the discs. Well, mine does not and I can't figure out why. See video.

Can you send us a video on you threading the machine?  We might be able to tell something from that.

Will do!

Will that resolve the issue of the pin?

It's probably the pin No25 that is the problem. It has a shoulder and the end is bigger. If this is inserted the wrong way round the plate can't push on it. The thin end has to go through a hole. Don't ask me how I know. Had me puzzled for a while. This has nothing to do with your tension issues though. Looks like you need to tighten up the top tension but I could be wrong. It has been known.

The pin No25 lives inside the center split of the top tension unit.

Your threading looks ok to me. After going through all the holes I like to make sure there's enough tension to keep the thread between the plates. More holes/less holes.

Here are some more shots. Not sure where #25 is exactly.

It lives in the center split and the thin end goes through a hole to the plate that you were moving in the first vid. It's job is to push out the black spring plate to release the thread.

This pin?

Pin 25 is in the center of screw 24. take off the tension nut, and the tension sprinrg.remove the black tension disk. next look down the center of the screw that has a slot in it AKA #24. the #25 pin is that hole.

 

corection not #24 it is #22

No. It's inside the split shaft  that the plates/spring slide on. If you take off the whole tension unit you'll find a small hole. Where No 25 comes through. Looking at that last vid it might well be that your tension is just way too loose. Tighten the knurled bit right up and see if there's a difference. That at least will take up the slack stitches on the back side.
