From the service manual for my 2017 SDGT. Imagine the SDR would be the same.

Cheers.

I'm offshore, looking at a electronic version of the 2017 SDR manual and that page isn't in it.

 

You looking in the owners manual? What I posted is from a PDF of the service manual.

That explains it!!!

 

Is it as simple as it looks? Remove M27 nut and securing pins then (I get this won't be easy) then remove the cush drive from the splined shaft. I would imagine there will be a reasonable about of friction to overcome.

Yes it is as easy as it looks. It should slide right off. Clean the splines and very lightly grease on reassembly.

The great friction comes only if you endeavor to remove the hub; that usually takes a nice dead-blow rubber mallet.

 

Out of curiosity, why remove the cush drive?

 

bought orange nuts to replace the cush drive ones. Despite people saying it is possible, there is no way to access the Allen head bolts on the inside of the hub. It might be that my chain is new and the hub is in its most forward position. After reading the replies above it seems easier to remove the drive and swap the nuts rather than scratch the hud or round the bolts trying to force a fit.
