clutch and gearbox help

Whoops, should have re-read the thread before posting. If it's not a delicate question, where did the rubbers come from ? Not that I've heard anything about bad ones but if someone somewhere is just using a "Do-it-yourself" rubber moulding kit then I'm sure they won't stand up.

I think you need to go back to the supplier but also be prepared to look elswhere for an alternative. At least it shouldn't be too expensive even if you have to pay for a new set.

No problem. They came from RGM, but they probably seemed clumsier than the bits left from the older ones. I'll order a set somewhere else and compare.

Did they come in the little baggy with the green globe ? Andover should at least have a note of what grade of material they should be using.

Can't remember... Don't think so.
I'd order them at BSA Regal, but it annoys me too much to ring them for every single thing I order and Norvil seems too expensive to me. Maybe there's a better place to ask for them?

Last ones I bought were more plastic in feel than rubber, had a glossy hard greeny surface.

I have a feeling that I've seen them described as polyurethane now you come to mention it. They certainly need to be pretty hard.

I tend to use Carl Rosner in Croydon (GB) for parts as I used to live in the area. He advertises a worldwide postal service in OBM and has always given me an NOC discount off of Andover list price for genuine parts so I have no complaints.

I would recommend Mick (and Angela) Hemmings, as they have always been friendly and helpful, and Mick is very knowledgeable, unfortunately they do not have a website which can be a little inconvenient these days.

Sparkplug,
The black spider web!! Happened to me one day. The little adjuster stopscrew on the rear brake pedal had decided to unwind itself, slowly binding the rear brake on. Not enough to be very obvious in traffic, but I did notice the bike wasn't happily revving as usual. Looked at the back wheel- -spiderweb time. Enough heat in the rear drum had been generated to melt the "rubbers" very quickly. I think they are some sort of neoprene. Easy to insert into hub, bit of a cow to get the wheel back on - tight fit when new. You need to grease them slightly to get the hub "fingers" to slide between them easily, and use some - ahem - persuasion to get the wheel, speedo drive, spacer etc back in. But it will go.

I echo that....I wrecked a new set of "rubbers" 2 yrs ago the same way but this was my fault with an overtight rear brake. I just could not figure out where the smell of burning plastic was coming from every time I stopped. Make sure you centralise the rear brake with the pedal applied when tightening both nuts.

Thanks, L.A.B. I always read yor messages and I really respect your opinions very much, but my spoken English is just ridiculous because of a lack of practice mainly... It would take magic to get my spares correctly by phone, and a letter seems to me so primitive and takes time to get to England (it's also romantic, but not for a spares supplier...). That's the reason I won't get things from BSA regal neither, as I don't want to call every time I order new stuff...
Maybe if I send a fax... but i can't do that from my house.

The rubbers come in "thick" and "thin" so you need to place the thick ones where they will take the driving load and the thin ones take the backlash.

Have you read Classic Bike June's issue?
There's an article about Mick Hemmings making a new Commando out of spares from just a bare frame in 48 hours! In one of the shots you can see how this rubbers are put into the hub: two of them are put the way you describe and the third one is put the other way 'round! :?

I highly recommend this article.

Type the order and FAX it. This way you can send card info and all.

No, Haven't seen the article. Rather given up on Classic Bike to be honest. Does it say that the intention was to place one set the other way ? Mick should know, judging by the way he used to hammer past me on track days. He certainly knows how to put a Commando together and wring it's neck ! I'm sure he wouldn't do something without a reason.

I'm assuming that Classic Bike didn't simply use archive photos from "Motorcycle, Scooter and Three-Wheeler Mechanics" from 1971

Ha, Ha..!! :lol:
I found it very interesting, specially for this forum members, where I thought someone would have written about it already...

About the bearings and felts, I've tried to check them but I can't take them off. What's the trick here?

Thanks! :wink:
