    CL77 front wheel hub rattle ??

    1967 CL77 305 Scrambler

    I took the front wheel off, removed the tire and pulled off the brake and speedo assemblies. When I rotate the wheel by hand I hear what appears to be pebbles in the hub. The bearings and seal are still in place. Im a little concerned.

    Any idea's?

    I just spoke to a guy in MD who specializes in CL77's. He said the noise is rust rolling around the outer rim of the wheel. He explained the way the wheels are made/designed and he said it is very common but not an issue unless you have a ton of rust with gaping holes.

    I feel a little better.

    That sound confused me with my first CB77. I didn't figure out what it was until I took the tire off of the rim.

    Rust inside rim is common to pretty much all old bikes with chromed steel rims
    It's usually pretty obvious it's coming from rim and not hub though.
    The speedo drive gear didn't fall out?
    You don't have a broken brake return spring?

    I'm not a complete idiot, but, I'm working on it
