Changing the my bolt in axle between 2 hubs last night and had a strange issue with the bearing tools (HTT174). For some reason the axle no longer fitted into the hole in the centre of the drift (step 10 of http://www.bikeradar.com/gear/article/workshop-replacing-the-main-bearings-in-a-hope-pro-ii-21339/), I know it used to fit as I've used this tool kit several times in the past. The smaller drift which is the same dimensions did fit!
Anyone had this issue before? I'm putting it down to the garage being hot and a difference in the expansion of the axle and drift (though why only half the drift was effected!).
