Title: Drive collar

I’ve taken the variator out and am going to replace the rollers with some DR Pully sliders. When I pulled the variator off the spindle I notice a very small amount of slop where the collar fits in the bushing, I.e. I can wiggle the collar a wee bit. Should there be any slop at all, or is this supposed to be a snug fit?

Radial (up/down, left/right) nearly no play (few 1/100 of a mm) . Only feelable NOT seeable.

But: more important the condition of the collar
Any pittings or flaked off chrome?

If not, its normal wear and tear or factory tolerance.  Bit (very little)  of copper grease or ceramic paste on it and all's well.
