I used the supplied ceramic grease to lube those return rollers and they are stiff at first, but will eventually loosen up after running the tank some.

For the plastic to metal, I used 5 minute epoxy and treated both surfaces by sanding them a little for a good contact area. It's been a 1 1/2 since the build and no plastic caps have fallen off.

I just finished repainting my 105 Sherman just a while back and should have some photos soon. Hope this helps!
