If the faces need work, I would think more about taking very light truing cut. Most of the faces I have seen have become grooved from being in the same location too long. Other than that I wouldn't do anything. Is the transmission slipping?

That smooth polished surface reduces wear on the width of the belt. Just clean it.
The pressure from the spring and from the speed changer loads the belt to drive
the sheeves.

One more vote against a roughened surface.
Think costly belt being turned into nasty carbonblack particles even more rapidly than it already does.

Chris, +1 to TDegenhart. Once you take the pulley halves apart (as you would have to for sandblasting without trapping grit), it's very easy to take a skim cut on most any lathe with enough compound travel to match the taper. Most old Reeves pulleys will have a bit of grooving, maybe even cupped faces, and the glaze you already see.
My own experience with sandblast surfaces is that you lose some contact area, so they don't really increase friction all that much. Your belt might spin and polish or re-glaze them fairly quickly. That said, I also don't think you'd destroy a belt beyond a bit of too-quick initial wear for the same reasons.

Okay people, it looks like it's unanimous. No sandblasting. I had also emailed Master Power Transmission at the same time I posted this question here......their reply was 'if sandblasting, the faces should be reground to avoid excessive belt wear'.
New belt, new key in the drive sheaves and new bearings in the motor should take care of everything.
Thanks to all
