    Karate Monkey Crankset Play

    Last week I broke the crankset on my RIP 9 so I switched it out with the Firex from my Karate Monkey. I just put the crankset back on the KM and noticed there's a bit of play between the crankset and the bottom bracket. It isn't as noticeable with the chain on, but it still seems too loose. Is there spacer or washer that goes between the crank arm and bottom bracket? I may have lost a part when I did the original swap.

    No spacers. Truvativ/SRAM cranks set up with one bolt. The spindle tapers down when it goes through the non-drive-side bearing. The arm pinches the bearing and preloads it. The spindle floats in the drive-side bearing. The crank bolt should be torqued to at a max of 54Nm. I always torque to that. If you still have play at that torque, regrease the splines and try again.

    Thanks for the reply. I just removed it and noticed that the extract bolt was loose. I tightened it up and it seems to have removed the play.
