Cheers.

Thanks for that appreciated.

It's the fact that someone who has made a few hundred postings is treating me like a newbie and has assumed I haven't already wasted ages looking, instead of asking where I've looked or just not commenting on this thread at all.

An exploded diagram is no help if shimano haven't exploded the part I've actually got problems with.

It's not that I don't know my way around a bicycle, it's that I've got no experience of this hub dynamo and it's almost like the innards are a state secret.

The wheel I was planning to use has issues that I didn't know about and the non-functioning spare I bought has been taken apart by someone else and reassembled incorrectly.

I've got a pile of bits, thick and thin washers, locknut, house shaped pieces, plastic bits etc that are simply not shown in the shimano breakdown.

Anyway, on the plus side, I think I might have worked out where the bits go and why, just am not sure if I even have all the right bits to start with or that all the parts I have actually go on the hub.

I certainly suspect that a s/h dynohub or dynohub wheel might be a false economy.

Next time I'll be buying a higher quality NEW hub.

Thanks for your reply.
