Using the new case and want to make sure thrust bearing is correct

The set screw/thrust bearing/nylon spacer stack is reversed. The instructions specifically say:

1.)    Loosen setscrew in shaft collar. Assemble feed screw by sliding collar all the way up. Tighten set screw.
2.)    Slide thrust bearing onto auger, then white nylon bushing
3.)    Slide flange onto auger, with curved side facing out.

So the shaft collar (the part with the set screw in the side, since you have to loosen it!) slides on first.
The thrust bearing goes on.
Then the white nylon bushing.
Then the flange.

Try it again and upload more pictures.

pipe -> flange bolted to case
then
shaft collar then thrust bearing, then nylon spacer then other flange on shaft side of auger.

This picture look correct?

How much play in the thrust bearing? This is pretty tight.

It is unclear to me what you are trying to say.

Just attach pictures like you did earlier.

Looks good, although typically the bolts are flipped around facing the other way. Otherwise, It looks correct.

You shouldn't need to apply a wrench to the barrel to correct for twist, ever.

If the barrel tightens during operation, you pull the 4 bolts out and rotate the barrel/flange together 90 degrees.

Of course, this means you can only get the cut in the barrel within 45 degrees of vertical, but that's not a problem - it will still feed fine.

I think the confusion with the flange bolt direction is that in the instructions for the Kit Enclosure it has pics showing the head of the bolts on the outside of the enclosure, on the hopper side, and the instructions for the Filastruder show them on the opposite side of the assembly. Probably doesn't matter either way.

EDIT:  In retrospect I think it is better that it is assembled so the bolt head of the flange assembly is on the inside of the Kit Enclosure so that the thread ends of the other side of the bolt help keep the hopper from potentially spinning.
