Big window spring

Bit of a puzzler.
I had a problem with the window adjustments and some of the teeth had burred over, I've managed to file them & it all works ok...But the big flat clock type spring not only pops off but when the regulator is working the spindle that the spring locates into pushes itself out of the housing & makes the spring come off?

Also I can see that the cam for the drop down would activate too soon as it is.
I followed the manual , put the serrated runners that guide the glass finger tight ,& the same for the two plastic clamps that fix the glass to the regulator ,close the door move the glass to fit against rubbers etc,leave the door closed & climb across from the passenger side &nip everything up...piannnnggg out pushes the spindle/spring
Anyone had this before ?
ps:One last thing,is there meant to be a circlip or retaing clip onto the split shaft?

Have a passenger side one here to look at and cant see anything holding the spring to the spindle -looks the same as yours,with just the the long end of the spring held in by the lug on top of the piece of metal it attachs to.Has the spindle itself come a bit loose?

Are the 3 teflon (i pressume) pads in place on the toothed arm? 2underneath,1 on the drive cog housing.Would allow some wobble if these were missing

edit: can see the white bits that hold the pads in the photos,so prob not this,unless just the pad bit has come off

I've just rebuilt my drivers door mechanism this week, and I found that the central spigot that holds the spring is very solid and looks like it's pressed into the arm. If it wobbles then it will tip the spring out.

Hey thanks guys for your help. I have no idea what the teflon pads are JRow?

Rod, my mechanism must be buggered as when I take the spring off it literally falls apart. I thought that a cirlip had fallen off but now it seems that's not the case? I shall have to try & find a press type clip , come to think of it, there is no groove for a cirlip...

I think thats knackered.
The red arrowed bit that looks like a washer around the grooved shaft in my photo is what holds the two pieces together. It isn't a washer though,it is part of the casting of the groved shaft,yours has disintegrated at some time by the looks of things

Thanks guys , I have an idea I will try ,probably futile but I have to try. I will weld into the groove where the spring is held at the top & spot weld on the small post on the other end,I thought of a Snap ring washer but I think the force is to much for that. I have to figure out if when assembled do I have to have to teeth on the quadrant fully to one end ie fully up or 3/4 ?
Nothing to lose as its cream crackered anyway !

YAY!!
Its systems go, welded the spring tab that sits in the groove .
After "much" fiddling withe adjustment & the drop-cam its all working, seals tight but still have 2 clicks when it's at the top of its travel . Ran out of time family etc but think something to do with top adjustment ?
Thanks all you guys for the help

OK ,that was short lived, the teeth started jumping again so I took it apart & I think its an alignment problem. Under & sandwiched between the two scissor type arms is a flat washer, I think its part a large rivet that joins to the underside where the spring sits & holds it all together, well this was missing & causing it to run out of true at the end of the travel at the top & causing the teeth to Jump/Burr etc. So I have bit the bullet & am waiting for a new one to reach me, with this sort though, as its aftermarket ,the lower rail pivot joint has to be riveted in place, not sure what size rivet though?

Apart from that I am happy with car as yesterday she sailed through an Mot with no advisories after I fitted a new horn.
