    Whilst stripping down the engine on my 97 trophy 900 as i removed the clutch the alternator drive sprocket fell out!!...the bolt had sheared off in the shaft i have had the stub removed from the shaft,does anyone know the thread size/pitch so i can source a replacement the triumph spares site only lists the long bolt replacement kit at £100+ for the kit.....cheers...

    are you talking about the 3" splined shaft?
    If you are I can do an exchange with a shaft that is drilled out to take an 8mm bolt and nut like the kit.
    The shaft is hard so you need a carbide drill to be able to drill it out
    Cost is £20 to cover cost/tools +post
    PM me if interested. btw a cheap nut/bolt is good as they are less brittle and so don't shear off but needs to be small head. again can be easily sorted.
