    I have been working on an Outback for my dad for awhile. We finally got around to ordering some new strings for it. I took the old ones off yesterday and noticed the idler wheel is leaning without any pressure on it. I noticed it when it was strung that it leaned at brace and full draw (worse) but assumed it was one yoke twisted more than the other. But I also feared it could be limb twist or a bent axle.

    Now with the pressure off I am thinking a bent axle or even that the idler is bent. How should I go about testing for one of these issues? How much am I looking it for each item?

    Thanks!

    :D idler lean isnt a huge issue ..even if there is a slight limb twist as all can be manipulated with the static yokes, and I doubt that the axle is bent …if the axle is bent you may have more issues such as a warped or damaged idler and/or cracked limbs…

    spin the idler on the axle …does it wobble?…spin the idler on a precise size nail punch as the axle…does it wobble…?

    I am mguessing it doesnt..

    try installing the new string starting with 12 twists on shelf side/left yoke and 9 on quiver side / right yoke and have shooter draw bow with good anchor and form….adjust so idler runs straight with string…

    Or if any doubts or concerns take bow into your nearest Authorised Mathews dealer..

    Neil, thanks for the help. I will do that.

    I bought the bow used and swapped the limbs out on it so its past history is a mystery.

    How freely should the idler spin? This one will only go maybe a half turn on its own.

    The only reason I think its bent is when looking straight on it cants towards the string suppresor arm slightly.

    :D The slight cant may be just a result of limb memory if new limbs were on bow for some time

    The idler should spin freely for a long time….remove Idler Via one E clip on axle…clean up axle and Idler axle insert..roll axle on flat surface…that will indicate and bend…
    lay flat straight edge on idler....that will indicate any cupping or warping…
    Spray some powdered graphite on axle reassemble and see how idler spins..rock idler back and forth on axle..should be tight or slight free play..excessive freeplay indicates a bearing issue..replace idler and axle..
    :D

    I took the idler off and it spins freely on the axle. The idle axle insert, is that the silver/black piece in the idler hole? How do I remove that? Seems like it is pressed in. It appears that idler axle insert if that is what it is, is rubbing on the inside of the limb fork on both sides.

    The axle looks fine as does the idler.

    :D The idler bearings are sealed and pressed in and not a maintainace item…the marks you see are normal if they are not grooved in…[which usually means bad bearing] if idler spins freely I doubt it is grooved into limbs :thumbup adjust shoot N enjoy

    have you seen this quide??

    Thanks for the help. I have looked at the guide and will again.

    The idler only spins freely on the axle when its not on the limb. If i put it back on the limb in the fork, it barely spins. The limb fork does have a groove from the bearing.

    If I hold the bearing between my thumb and index finger and spin the idler, should it spin freely?

    Again thanks for all the help! I am trying to get this bow shooting for dad.

    If I need to replace the idler/bearing, will the idlers off any other Mathews work?
