The anti-rotating washers on my Nexus 8-speed internal hub axle are opposite to what every service manual I've seen suggest they should be. In particular, the yellow washer is on the left side and the brown is on the right! As well, the tab on these washers is on the down side of the dropouts whereas the photos I've seen all appear to have the tabs on the up side! I should add that I have a Shimano Rollerbrake on my bike.
Can anyone explain why my setup is different than what the manuals show?
