and its run ok for 30 years like that? Just a small point (well quite a big one actually) not all the drives need spacers. I got caught out with similar thread a few years ago and tried to install one and found my drive had a smaller dia hole into which the spacer would not fit. It also has a slightly raised area on inside to do the spacing function. No idea where it came from as it was on the bike when I bought it in '98.About 1980, I needed a new one & could only get it with an exchange. So I rode up to L&D motors in Bristol, me & the missus lifted the bike up (no centre stand) & swapped them over. Should imagine the top hat was still in the old one.
Hmmm...that seems to be what I am experiencing....trying to fit TopHat as per AndoverNorton exploded diagram for '74 850 hub....the TopHat will not fit into the gearbox axle hole from out or inside. If I slip the TH into the hub axle hole, with the flange facing out to the speedo, then the speedo does not seem to mate up properly with the notches in the hub ring. It's the raised ferrule inside the speedo that prevent the TH flange from seating further into speedo housing...gap of speedo casing to hub plate is like 1/8".and its run ok for 30 years like that?

New one pressed in using vise jaws...but managed to bend rim of casing some...should used a block of wood behind to better spread loads.
Gear still turns as good as before...a little catchy, jammy, likely needs replacement ...but speedo now sits further off hub plate than before, which is a good thing....plate is gouged pretty good despite having old spacer in there...maybe just too mashed up?
If you mean the thin dish shaped chrome hub cover 06-2082, Walridge in Ontario has them on sale for 22.50 till the 31 of MarchThx for the advice. My hub plate is already chewed up where the speedo was pressed up against it. Just checked pricing on these things...$90+ CDN from in country suppliers. Are there rebuild procedures/parts?
