    Thanks Steve.
    My hub feels like it’s an original and I’m pretty sure it was made for ball bearings much like the front hub just larger.
    It may have been swapped out for an earlier model at some...

    I am restoring a 27 J. When I dismantled the engine one of things I found was that the rollers that run on the cam lobes were badly worn. In fact the whole roller arm mechanism was worn which was...

    Thanks all.
    Steve, T&O did not fit the pinion bushing for me. I kept the cases here in the UK to work on while they built the fly wheel assembly. I found an expert machinist who was able to sort out...

    That’s good further information thank you. Who is the author of ‘motorcycles and side cars’ ?
    I imagine it’s long out of print but worth looking out for a copy
    Thanks

    Steve,
    That’s great thanks. As and when you get a chance I’d sure appreciate the further information stored in you files. At least I know now that it needs something in there.

    Larry,
