Dunno 'bout you guys but when I remove the rear wheel I only remove the caps off the ends of the swing arm, leaving the axle , spacers ,sprocket carrier , calipur bracket and excenters alone. And I use a big allen key to turn excenters , but I did make sure that there were no rough bits on either the swing arm or the exceters so that they would rotate smoothly ( I stopped short of lubing them ..... just ), maybe some new nuts might help
. I have a piece of wood just the right thickness to fit under the rear wheel while its on the center stand to hold the wheel ( assy) at the right height to remove and reinstall easily ( this is where any free play in the linkages is handy, I have about 3mm ) . Unbolt the rear calipur off its mounting bracket 1st and then just drop it back on last.
