    Doing a cable and string replacement on my LD and realized my cam is rubbing on my limb…been going on a long time – I’d think I remember hearing it a time or two…

    Anyhow – back in the day of double yokes, I’d just plan to adjust my yoke to take the rub out — and maybe that is the thing to do – but with all the strings off – when I spin the cam, its rubs the limb so I’m a bit worried the cam might be warped (I can’t see a warp) or maybe the limb warped…

    Any opinions/experience with this?

    The carbide in the cam is not hitting the limb correct? Or it could have a bad bushing.

    The edge of the inside of the limb – near where the limb splits, has been
    rubbing on the cam for awhile…I don’t recall hearing it during the draw or
    shot cycle – just saw the wear when I was replacing my string and cable.

    I checked the bushing very carefully and it seemed fine..no wobble smooth
    and quiet, the axle itself rolls forever on a flat floor…when I put the
    cam back in the limb, it will rub while spinning around the axle-right at
    the spot shown on the attached photo…

    I didn’t hear back from you guys for over a week, nor my dealer who I bought
    the bow from back east, nor a local dealer (where I left a message)…which
    wasn’t the best situation…

    So I put it all back together with new strings and cables and tuned the
    idler and timed the cam and I can’t hear it rub…I’ll paper tune it the
    next couple of days – but just in the shooting to seat the d-loop and let
    the peep settle in, it seems to shoot much, much better…

    My theory is either: string wear had it rubbing slightly as the cam came
    back to rest during a shot cylce (cam outta time maybe – but never heard of
    such) or – I suppose its possible the limb’s axle holes are not perfectly
    plumb…

    Suggestions?

    Could also be cam slop. Press the bow enough to relax the string and see if you can move the cam side to side in between the limb. Now if it just barely moves it is fine, but if it moves alot then that could be the problem. The fix for that could be as simple as replacing that white bushing or the limb. Are you the original owner of the bow?

    Yes I am the original owner…

    I already checked that…cam fits tight…I’d call it a perfect fit.

    You will need new parts to fix it. Please contact an authorized mathews retailer. If you need to know the closest ones too you please pm me your zip code and i will get you a list or you could use the find a retailer tab on top of the page.{#emotions_dlg.mathews_peace}

    Yea…I already did that…the closest one to me is almost 3 hrs round trip…

    If its quiet…and assuming I get it papered well, I’m not gonna bother…Like I said…I can’t hear it rub only when I got the string off, can I see it appears to have been rubbing as I could spin the cam on the axle – I don’t know how it was timed with the orig strings…just that it started shooting very poorly…now I have new strings…seems to be much better and I can quite tell how that part of the cam was rubbing on the limb…as I draw, that part of the cam does not seem to pass thru the limb.

    that is “can’t quite tell” how that part of the cam was passing thru the limb.
