    I've been trying to find a bearing for the tensioner pulley ...the bearing # on it is B17-40DUML.
    The ones available online are 12mm in depth. the one I need is 21mm. Any help would be appreciated.

    You might find what you are looking for in this link. Hopefully it’s in there I didn’t have time this morning to read the entire thread.

    Usually the bearing element wears out before the physical pulley or tensioner.

    $20 - $50 for replacement bearings vs:

    Plus the brg is a simple 20-30min repair compared to a Pita 2-3 hr tensioner swap.

    but that's only if you can find a bearing.

    i'd just rather be done with it, and order the $100 assembly than spend crazy amounts of time to save $50.
