    07 Trance 3 Bottom Bracket- TruVativ Power Spline

    I am looking to replace or at least try to tighten the stock bottom bracket that gives some play when pedalling. Does anyone know what tool(s) I need to get to work on the bb. Its a TruVativ Power Spline. The crank is a TruVativ 5D and I have made sure it is tight with the right size allen wrench. I'm assuming that this allen wrench is all I need to get the cranks off.

    I have read up on the bb on MTBR and can see that it is pretty much junk so I don't mind upgrading it.

    Just tightening the crank bolts may not remedy your issue with a play at the BB area. You might have to remove the cranks and find a BB splined tool to tighten the cups into the BB shell of your frame. Do this in the following order.
    1. remove both crankarms (you might need a crank puller) can't remember
    2. loosen non-drive side cup a little (1/2 turn)
    3. tighten drive side cup until you cannot turn anymore without using mega amounts of leverage.
    4. snug down non-dive side cup firmly.
    5. check for play.
    *if play is still evident, you need a new unit.
