I'm trying to remove the brake plate from a mark 2 spring hub. The wheels been sitting a long time, I imagine, and after removing the parts described in the manual, there is now nothing preventing it coming off, except it is stuck solid to the aluminum hub. If I remember correctly, the plate has about a 1/4" wall that slides over the hub, and I suspect there is some kind of reaction gone on between the steel plate, and the aluminum hub. I've tried some heat, and right now it's soaking in WD40, but I suspect it's not going to work. Any suggestions? Les
Does the brake plate thread onto the spring box? No threads are shown in parts book like the Mark 1 pictures.Its been a while since I had one apart . Don't open spring box without longer bolts and spring compressor as in Nicholsons book or the old manuals.
Hi Bob, no threads, its a mark 2 hub, and it was the mark 1 that threaded on. I know this because of the hours I spent many years ago, trying to remove a mark 1 brake plate by pulling at it. I am not touching the spring box, I heard the horror stories. Les
Thanks for all input. Patience and perseverance did win out in the end, aided by brute force and ignorance. The drive side of the axle has flats on it, which I clamped in the big vice I have, placed an extension tube over the brake plate bracing arm, added heat, WD40, and a little persuasion from a large hammer, and it moved. After that, it was just a matter of forcing it back and forwards till it slid off. Les
