Found this series and have spent hours watching it. I'm enthralled. Up to clip 72 so far. As I watch you working I imagine myself doing it...and buggering it up! The Vincent is so beautifully made. Unfortunately I am a lot less mobile these days (at 82) but still ride my '08 Can Am Spyder GS SM5 & 2015 Honda PCX 150 Came over from the UK 60 yrs ago. Keep up the good work.

Hi Michael, many thanks for taking the time to write. I appreciate it and am glad that you have enjoyed the series. It turned into a lot more videos than I planned, but was a wonderful experience. Great to hear that you are still riding. Best wishes, Mike

vincent ahead of its time, ill say that again, pure genius.

I like that "slotted trunnion", might have to make one for my Harley. You Brits have some interesting words, like "gudgeon pin, mickey mouse nuts, and "tommy bar nuts". And then there's "the Meccano, or erector set, for America". Thanks for sharing this, I always wanted one, never had the chance over here in America.

What a machine, everything was so well thought out, pure genious.

Love the way you work on your bikes, like a working on a fine watch.

Thank you very much Colin! I'm glad you like the videos. There are a few more in the pipeline and then I'm hoping to switch to the other bikes. Best wishes, Mike

so glad to read the very dangerous issue did not cause you injury or the bike significant damage. glad to you are replacing all the related parts so all will be good for rmany many years to come :)

Thank you Malcolm. Yes, I consider myself lucky on this one! The replacement parts should be on their way now and should be pretty simple to install. Best wishes, Mike

I watched your video with great sympathy as you realised the extent of the damage to the sprocket drum assembly. The cause seemed so simple yet so easy to be trapped into. I hope you can get it rectified quickly. In my youth I longer for a Vincent engine as I wanted to add it to ny feather bed Norton frame. I know this may sound like sacrilege to a true Vincent owner. A friend of mine beat me to the punch when an ex-sidecar racer had his Vincent engine for sale. He was loading it into his car when I arrived to look at it. I ended up using a Bonnieville motor.

I had a Triumph Bonneville, back in 76, never got the Vincent I wanted, and I miss the Bonneville. I owned some 13 Yamaha 650's, while on recruiter duty in the Marines, in Va, bought out a guy's basket cases, and put about half together, and then the one I kept was stolen. I've got a custom harley I built in 95, but it just isn't a Vincent. I can only dream, lol.

Wow! Too long bolts possibly aggravated by heat generated from braking may have caused the drum to finally crack from the pressure. I continue to be amazed by all the little engineering details on this bike. So much thought went into the design of all the components to make it rider/mechanic friendly for servicing.

Oh dear, oh dear. I'll be sure to remember this one if I ever get my hands on a Vincent in my lifetime!

Nice to see the Avon Roadrider tires on there.

What a nice and handy motorcycle lift you have ! I’m a structural engineer. This is what we call a shear failure, and a very long one too. Rarely seen.

Thank you Jean-François. I think it must have been happening for a long time according to the rust. Best wishes, Mike

At least you have found the answer to your problem, that has been a problem waiting to happen since the sprocket was fitted, the hub spoke flange bolts can also give trouble, but I see you have hex bolts with one flat machined smaller rather that the eccentric head type. good luck on your replacement parts, and stay safe away from other people!

Many years ago I was involved with a London Bus Preservation Society. We had a friendly commercial wrecking yard where the owner had been an apprentice for London Transport. He used to put parts aside for us. One of the split rim wheels he gave us had a slightly different curve, unnoticeable by eye & put pressure on the brake drum. The end result was the same as your bike. we only realized why the casting had cracked from some witness marks.

It'll be interesting to see how hard it is to remove the ten fasteners that hold the drum to the hub with all the spokes in place. Could be slow going with not much wrench movement possible in such a confined space. Good luck, Mike; I know you'll persevere in the end!

On reflection the fiber lock nuts are on the spokeflange/hub I have thin nuts & dead size bolts (with small gap between sprocket flange and first rib of drum) on the shadow.

Looks like a few spacer washers under heads of those bolts would have prevented the interference, or a little grinding protrusions beyond the nuts.

Ahhh I knew there had to be a reason leave it to Mr Stevens from KTB to detail just what happened... Time to go and check all the nuts and bolts for correctness! Once again glad all is well elsewhere on the bike. Was thinking if you swapped the wheel around and had a sprocket on the other side you could have just spun the wheel around to get home. I knew thee was a good reason Vin's had that extra sprocket..LOL Cheers Mate, Eric

Someone who thought they were good mechanics fitted the wrong bolts and levered it apart… The rust you see on broken surfaces of the drum is from where it cracked earlier and rusted. Hope you get it fixed ok,

You need a new drum. This can not be repaired as it turns and must be centered. You can not weld this thin cast iron. Please note that there are no washers under the heads of the bolts which may have provided enough clearance to prevent this from happening (again) ? Also please note that appears on the drawing that the bolts are installed from the other side. Ah-ha !
