I have a 2012 F800GS with 50 000km. I have replaced the 2 bearings in the rear wheel hub. Heating the hubs for a minute or so with a heat gun made the removal much easier with the blind extraction tool. I therefore also pre-heated the hubs before driving in the new bearings. The Haynes manual recommended the draw method (with a threaded bolt) to replace the bearings, but I drove in the left hand bearing first and fitted the circlip. I then carefully drove in the right hand bearing until the spacer had no lateral movement, but the bearings still tuned smoothly. I initially drove in the second bearing slightly so much, as the bearings were not turning completely smoothly. I lifted the second bearing slightly with the blind extraction tool and drove the bearing in ever so slightly until no play of the spacer, and the bearing turning smoothly. I would like to know if this would be acceptable instead of using the drawing method. I am concerned that there would be lateral pressure on the bearing when the axle bolt is torqued.
Out of interest, the bearing in the sprocket mount was gritty - it had a white deposit on the bearing, possibly caused by water or salt water. The bearing in the wheel hub felt smooth but I replaced them anyway.
