Spindle Adjustment & Eccentric Maintenance
If the eccentrics do not come out by hand after backing the set screws out by three to four turns, then you may have to rotate the eccentric to break it loose.
Use a 36mm wrench or pin spanner wrench and work the eccentric back and forth until you can work it out of the shell.
Removing the Spindles
Collared Model You will need to loosen the three set screws on one of the locating collars. The set screws take a small 2mm allen wrench, so take care to stick the allen wrench all the way into the set screw before loosening or tightening. Only back the screws out ½ to 1 turn. There is only one place on each side of the eccentric to get to the set screws. (See illustration). You will only need to loosen one of the locating collars in order to remove the bearings and spindle. Next, tap the spindle out from the same side you loosened the collar. If the spindle does not come out by hand, use a soft mallet or block of wood to tap it out. If you remove only one collar and remember which direction the spindle came out, you will not need to realign the spindle for proper chainline. The shorter spindle goes in the front.

The shoulders are not centered on most of the spindle lengths, so mark the direction the spindle came out and reinstall in the same direction for proper chain alignment. The shorter spindle goes in the front.
