Check out THIS pic. I posted it awhile ago. Should be the same PV's as the XF8. You may have to "View Original Photo" to see it in any detail.
Personally, I don't remove the cables as described. I just remove them from the cylinders, and clean them over the top of the motor (laying a heavy towel over the motor of course). If you're careful, you can even remove just the valve itself from the mechanism and clean it. You'll want to be familiar with it before you do so, I had a helluva time getting it back together the first time I did it.
