2 3/4 patent plate clutch
« on: 25 Jun 2017 at 20:25 »
So to continue with the clutch the nut was left hand but it was tight needed hot spanner, The picture attached is of the stripped pieces. So anyone know if it's correct I know there some three legged part missing that I think is essential to the operation of the clutch anyone got a decent picture or drawing of one so I might recognise if I see one or work out how to make it,pushrod length would help and there's rivets in the basket as if something was attached to the perifery any ideas or pictures Best wishes Andy

Originally, these clutches had a spun sheet metal, domed cover to prevent foreign objects from getting into the workings. The cover was a bayonet fit on the rivets (Look at the 1923 4HP Model B in the photo guide). This type of clutch seems to have been more common on 4HP machines than the 2¾HP's.

Regards,
              Eddie.

Hello Andy
          I note that you live in Lancashire, so do I.  I have the same gearbox and clutch as yours. Seeing things in the flesh, so to speak, should be much better than a load of photos.  If you care to PM or email me you could visit me and I can show you what you need.  They're not for sale though, 'cos they belong on my bike !
Regards
           Richard
