A difficult one to answer and know what is right. I have often wondered how shiny they would have been when new, did they have a protective lacquer of some sort? But if they are badly corroded and dirty then some cleaning will be required, I suppose the ideal would be something that can remove the dirt and corrosion without too much polishing.

Alan, I was thinking the same, it will get the information to all members and hopefully prompt a few to add other sizes to give a more complete picture. Something that would be useful is an additional column with the modern equivalent size if available.
Hugh 10×2 would be overall tyre diameter and width, 4.00-6 would be rim width and wheel diameter, so not sure it is correct, 2.00-6 would be more likely.

Don’t be too gutted, it may not be too late to save it, at least it has not gone for scrap.

Added a couple more to the list, if you have others to add please let me know.

Hugh that is an excellent link, covers just about every way tyre sizes have been and are given.

[charlie]

Just had a thought. It might be a good idea to build a list of machines and what size tyres they use. This would give a better idea of how common or not each size is and where tyres are interchangeable. To make a start I have listed a couple on the attached.

That is a pity, looks like engine number will be only option now.

Have you tried Tyre-Finder or Micheldever Tyre Services? Tyres are one of those parts that can be a real problem to replace on some machines as many are obsolete sizes eg 3.00-6 (12×3) for Monro Tiller and small Barford Atom.

If I remember correctly the chassis number should be on a brass plate attached to the inside face of the chassis on left hand side (when viewed from rear) below and forward of engine.

I have a manual which I have scanned and can e mail to you, please see personal message by clicking on your user name when logged in.

One of the later gearbox manuals I have has the name Hi-Ton Transmissions on it, I don’t know if they can help.
Another source maybe one of the vintage motorcycle parts suppliers.

Looking in the parts list for the later type it would appear the clutch is on a keyway but I cannot see how it would come off. Plenty of penetrating fluid (not WD40) and some heat maybe the answer. For the clutch to work the outer needs to be able to slide freely on the shaft.
Not sure if early clutch is the same.

What spark plug do have fitted? If you look on the Green Spark Plug Company website and look up your plug it will give you the hex size.
Suitable tyres can be obtained from motorbike tyre suppliers. The original tyres had a unique tread pattern for the Allen Scythe.

Barford trailers, flat bed or tipping are a bit like hens teeth and rocking horse S~*t. A well known online auction site much used by our members is where I got mine from. The dump trailers are prone to rusting out at the bottom as they fill with water if left outside.
