You are welcome!

Ahhhh, the tension release slide.  I've seen many of these poorly made on brand new Chinese machines...it's not the 1st thing you want to have to replace on a new machine.

As you can see, it's a big job to replace.

 needle bar rock frame out, goin deeper.  thanks for all the help.

[Primosand]

just a bit deeper

So I opened this oil resiovor cap (I think it's an oil resiovor) and this little pin was just sitting there on top of two stacked wick plugs 

It doesn't seem to belong. Does anyone know what it is for and where it goes?

 

thanks

That looks like a bed slide pin for holding the right slide plate from coming completely off.  I bet someone before you took it off and dropped it in the oil hole.  I would keep it but not use it and put it in the drawer.

right, thats the slide plate pin. There should be a small spring too. maybe its still in the hole.

Slide plate pin ........ thanks again guys. I'll look this up in the parts list diagram and see where and how it goes and see about the missing spring.

So my replacement "tension release slide" part came in the mail yesterday. It was shipped in a soft side bubble wrap envelope and the bendable part #10546 was sticking out the side of the bubble wrap. The arm broke off the part as I removed it from the bag.

Before they sent this to me I talked to Sean at Aberoni sewing and he told me that this is a quality Japanese made part that they use all the time. Another guy at the store said that of the two styles of parts the old style with the arm simply bent up at a right angle was the supirior part. He said that the one with the post added, the post will break off and was an inferior chinese part that runs about $3.00. When I asked why they mail of a bendable part in a softside bubble wrap envelope and not a box he said that other part venders ship the part in regular envelope (no bubble wrap) and that there method was better and saved money.

I recommend the original Juki part. When you compare the two versions side by side, the difference are quite obvious. One key difference is the that the top section of the vertical flat slide part is machined to be thinner than the rest of the metal stock. I think it makes a difference and allows for smoother movement and more pin-pushing action. 

ABC Sewing Machines sells the Genuine Juki part for $7.33, which in my mind is trivial compared to the effort it takes to install it. It may take a week or two to get them (I ordered a bunch of them). MJ Foley has them too for about the same price (and they include the Pin that goes inside the machine.) All my parts from both ABC and MJ Foley arrived in boxes, unharmed. The parts worked perfectly on all my Juki and Juki clone machines. 

I installed one of these on my Consew 225 today. It took a fair amount of fiddling/filing/polishing to make it work on the Consew (the vertical sliding part was a tad too wide for the Consew mate). But now even my Consew 225 is a happy thread tension releaser.
