Swinging arm bushes.

    Hi All,

    So, I have had the swinging arm off this 61k CB Two-Fifty shot blasted
    and a mate has painted it for me but I'm not sure if I've jumped the
    gun getting it painted?

    The reason I ask is that I'm not sure if I should replace the bushes
    etc while I've got it all stripped down?

    A new set of parts [1] would be 60 notes which whilst quite expensive
    (to me and on a 15 yr old runabout) I don't mind doing so if it's
    going to give me a better final product (and thinking the Daughter may
    well be riding this later on).

    A couple of the existing end cap / seals are showing signs of wear
    (potentially allowing sideways movement on the arm) and the pins are
    showing signs of wear in a highly polished area at diagonally opposite
    sides / ends of each bearing pin (no noticeable step / ridge though).

    Placing the pin in the bush doesn't reveal loads of slack so I
    question if a new set would actually feel *much* different?

    Yes, I could bung it all back together and stick it through the MOT
    (an I guess it will pass as it hasn't done many miles since the last
    pass) and I can always strip the arm out again later and replace the
    bearing but it would be much easier to do now while it's all out.

    So panel, is this one of those areas where it wouldn't make much
    difference if it wasn't 'perfect' (especially considering what the
    bike is etc).

    All the best ..

  2. If it's OK now, leave it. As you say, it's not a hugely tough job
    anyway, and who knows whether you'll keep the bike that long anyway? If
    it ain't broke, etc etc
    Exactly.

    Nope, quite straightforward. To get the main stand off you have to
    remove the exhausts and that wasn't quite so straightforward (mainly
    due to seized nuts etc).
    Well, I don't have any intention of ever getting rid of it, the only
    time I might would be if it become uneconomical to d-i-y repair or if
    something 'better' came along (equally economical / reliable etc).
    Oh indeed ... just didn't want to miss an opportunity, especially if
    it had made a difference to the ride etc.
    Fairynuff, it goes back on with just the new end caps (seals had been
    caught previously etc) and some good lube.

    All the best and thanks TOG.
