how did you get the arm off, did you use a crank puller that screws into the end? just bolt the crank arm back to the sprocket, then try removing them together... if not, I really don't know what to recommend other than elbow grease and time/frustration, haha... good luck!mrbray101 said:It doesnt want to just pop off. i dont really want to whack at it with a hammer because i dont want to damage anything besides the chainwheel. any idears?
yeah good point. I would take the whole thing apart, you shouldn't be beating on anything in your bottom bracket. If you just take off the other arm, then you should be able to remove the spindle the opposite way from the ring, then beat on it on a table or at least get a better look at it and not risk tweaking your bearings or cups.sittingduck said:Can you try pulling the spindle out that side? Maybe taking the other (non drive) side apart will allow it to slide out with the chainring. It almost looks like there's a flange on the outside of the spindle, and the chainring will only come off the other way.
oh wow... ok...mrbray101 said:Thanks for all the help, ive been really busy this week so i really havent had a lot of spare time to work with it. Anyways here are some pics, just let me know if you have any ideas. Thanks again!
I tried pushing it out after taking the other arm off, it seems like it doesnt want to do that...
I found on GT's website, the bottom bracket is a "ball type bottom bracket" if that helps at all.

what would be some nice ones to look at, not cheapos but not the top of the line.
Also, how would I even take this BB out??
I guess I need a spanner type wrench with the two pins to hold the lockring or whatever that is and spin the nut on the non drive side.
Nice! you got it apart.mrbray101 said:Yep, sitting duck you are right, I got it off. My new sprocket (29t profile imperial) wont even fit on the spindle so Ill just look into getting another one.
Will any 3 piece crank with bottom bracket fit into the BB shell or does it have to be a specific type like American, Euro, etc...
Thanks man, I ended up getting it off. Ive got a new 3 piece crank on order now and it should be here in a few days. my bikes only an 06 so it still had some grease left in there. But, that BB was so weird, it looked more like the old 1 piece cranks they but on cruisers and older bmx stuff.warsaw1776 said:pretty sure its just stuck on there....i think i tried taking it off cuz at the time i just wanted to turn it around the the gay pic wasnt going to be showing.....but after a lot of hassle i just kept it on there.....and yes....just spend the money...you will be way happier...anything it going to be better.....and if yours is anything i like mine was be care with the bearings, they are in a cage but if theres no grease like with mine, they are prob thrashed and will go everywhere. if i get a chance to look my my old one(its at my girls house and i spend much time there) i will try and check it out for you.
