orientation of non rotating washers (Nexus 8-Speed Internal Hub)
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? Thanks |

orientation of non rotating washers (Nexus 8-Speed Internal Hub)
Thanks all for responding but I'm still searching for an answer. The washers I have are a matching pair however the yellow is marked 5R (for right) and the brown is marked 5L (for left) but they are installed opposite to the marked sides! I've sent a message to Brodie (my ride is a Brodie Section 8) to see if they can offer an explaination.

Thanks I don't know why the arrangement is different on you bike but, assuming it isn't just a hungover Monday assembly problem which fortunately hasn't killed you yet, we can all speculate. The document you want if you don't have it already is http://techdocs.shimano.com/media/te...9830600211.pdf Speculation: Those anti-rotation washers are handed and oriented the way they are to account for the orientation and angle of the frame end, what the crude and ignorant call "dropouts". A pair of washers if swapped from side to side and/or turned upside down so that the "tongue" is at 180 degrees to its previous orientation, will give the designer more possibilities for aligning his frame ends. Is there something odd in the alignment of your frame ends, not covered by the table on the document cited above, but covered by a bit of vector thinking as described in the paragraph? Still speculating: Alternatively, it may just have been a supply problem: the recommended washers may not have been available, so a lateral thinker ordered the ones that by turning them around would do the same job. I remember having to wait for the precise washers I wanted, while others were freely available, and wondering if I could swap make the available ones do in a different orientation, but it wasn't urgent as at the time I also had a new Rohloff to play with, so I just got the right ones.
