Replacing a rear hub dust cover, rivets 57â

Hi

I am working on a 57â 19S and probably want to replace the dust cover on the rear hub as it is rather dented

It is held on by rivets, I know later they switched to screws

Any advice on removing and replacing the rivets?

How are they attached inside the hub?

Where could I get the right peening tool?

Thanks, Mark

Good Luck, the rivets are hardened and the only way is to carefully drill them with a sharpdrill, asmy replacement hub cover cam with screws I used them though a little ali welding was required where I went off the rivet. Be aware that the 57/58 M50, ES2 & 19S are different to earlier and later models. Neil Wyatt who is regularly on this forum and my self have already been down this road with this model year and hopefully may be of help to you though as I amin NewZealand I am a little way away.

Mark,

What Alan says is spot on. I bought a new polished cover complete with a set of stainless self tappers and three rubber grommets from RGM.

Gently grind the top off the rivet and use a very fine drill. (Smaller diameter than the widest part of the self tapper) Or you could simply drill through the rivets as Alan suggests. I found the metal just about soft enough for the self tapper to secure the screws. Keep checking to ensure the holes line up.

That's about all there is to it. You don't need much of a hole.

I hope your machine is complete as these models are not well supported for spares, where they differ from F/bed models.

Let us know how you are getting on.

Thanks Mark for introducing me to the most interesting Norton forum I didn't know existed.

Personally I would replace the rivets with rivets for originality. Self tapper would not look right. They are probably simply round headed rivets with a spiral shank. They may even turn themselves out of a left handed drill were used. (never tried)

Those are not really rivets. They have curbs on it. Something like this: http://www.norvilmotorcycle.co.uk/061287.htm

I've slotted the head with a Dremel, not to deep, so it can be turned out like a screw, sometimes.

Mark, I could tell you were from stateside, you say Fender and I think guitars! Alan in NZ confirmed to me that apart from a couple of holes, your rear mudguard (Fender, hee hee) is the same as a wideline. That should be good news but the club has no more stock and it might take 100 years before they get any! I was being serious...discuss!

If push comes to shove, Fred Williams can always make you a front mudguard.

I was pleased to see you have the attachment that links up the swinging arm and the rear of the engine plates, over the gearbox. Skip B managed to secure me one of those on US Fleebay and I have never seen one for sale since. I have the earlier one if anyone needs it. (56 and before, screws on both sides of the swinging arm)

I didn't see the rear tank mount but that can be made if you don't have one. You can buy the cups and rubbers from Norvil.

Undoing bodges (Sorry, temporary repairs) is to be expected but just take it one bit at a time. Thanks for the update.

Thanks for the photo Mark, paints a thousand words.

A headlamp shell might be difficult to find and the chrome tank side panels. But if the holes in the side of the tank have been filled in and smoothed over it may be as well to leave it as it is and put a transfer on the tank.

The good news is that you can still buy a new exhaust system and there doesn't appear anything missing to keep you getting the bike on the road. That would be my initial target.

PS: if you don't find an original headlamp shell you can always mount the Speedo on a bracket until you do.
