IF it is not already apart, where did your pix come from?

This would be a good time to actually remove the Pinion Assembly and Quill Return spring for a good cleaning. Sometimes sawdust gets into the spring housing and causes it to not allow the quill to extend all the way. The more sawdust in it the less room there is for the spring action. Keep us posted on your progress.

In the picture the JPG labeled "looks mashed" should be a domed washer, and in the picture it looks like it is either mashed or simply the wrong part.

BTW we have been instructed to not to clamp the wound spring when the quill is out. I think it was perhaps Nick that mentioned that. Before that I too did it that way but have sense changed my ways.

I had not removed the feed assembly yet as that is not part of the powerpro upgrade. I know it is most unmanly, but I'm following the instructions.

I'm going get a new feed assembly ordered. In addition to the wear on the gear, the spring feels kind of weak, and that washer was distorted to the point that I had to cut it. It wouldn't slip over the key in the shaft.
The new quill is a tight fit and doesn't move smoothly, but I think at this point I just need to work a little more with polishing up the bore.

JPG's "Whatsat" is also present on my casting. The metal is comparatively bright near the top where the outside wall meets the thick part around the Quill. It is in the background in the OP's picture. I looked in another thread where it was not present. Maybe a Rev C headstock feature?

Do you recall why? I'm just curious. I always thought it was 'do it either way depending on if you want to check the pretension.' Only thing I can think of is to keep it from snapping back if you forget to release it gradually.

The tip about the quill missing and the locking the spring was a long while back and I don't recall if they said why. Nick use to go out to the service area and bring back tips on and off. An advanced search might locate it??

A couple of other points, I would get a cotton q-tip and run it along the top of the quill where the slot is. The fibers catch on very small burrs that might be there. Once found and filed off the q-tip should not catch any fibers anywhere.

The quill needs to be waxed. Wax on let it dry then polish off. I would do this at least twice to make sure it was waxed everywhere. A tooth brush works well for the area with the teeth.

The quill is a harder materal then the gear so pretty much every time you put a new quill in you will get some small bits of metal wear off. I wouldn't think the gear needs replacing. A good cleaning and again you can check for burrs and file them off if they exist.

The spring is wound and you can wind it how you want it. If it is not returning the way you want an extra half or full turn should fix that. I've not found a sping that was "weak", not saying they don't exist but that I have not come across one in that condition. I personally have preference for a little looser return for most times but also have no issue with redoing it for specific tasks.

The domed washer should have been able to go over the key, if it was deformed someone must have really tighened the quill. I don't think one can bend the ears in the head stock but then I wouldn't think you could bend the domed washer....

The pinion gear in the third pix look strange(worn?). Nothing like the good looking teeth in the interior view.

Also unexplained is the earlier pix that shows something in the gap off the side of the pinion gear.

Regarding the domed washer.

IIWM, I would replace the domed washer before PP upgrade installation.

If it will not slip past the woodruff key, the key may be removed to allow removal. Tricky but possible!

You are wise to resolve the quill issue first.

A very uneducated guess, here, but I'm assuming the problem will be on the quill. Could it be slightly bent, or the teeth or the ways be somehow not quite straight?
