Messed up crank
Hey guys I'm new here and need some help. Recently I have received a redline proline pro 24 bmx bike and it has some problems. I fixed the flat tires and now I'm trying to get the crank fixed. The guy I had it from before had the crank all apart and I have no idea how it goes back together nor does he. I have a pretty good mechanical incline (Ive changed motors in cars) I just have no idea how these go together or whats missing or even a good online seller to buy the parts from. So if you guys could help me maybe a diagram or something that would be great Ive searched on the internet with no avail.
Also i can take pictures of what i have if you need it
Sealed or unsealed cranks?
(crank arm)(spacers)(BB1)(BB Spacer)(BB2)(Spacers)(Sprocket)(Crank arm)
Spindle goes through the bb of course.
If it's unsealed, it will require a lot more explaining and pictures.
well i can tell you its a euro bb and i think you need a bb tool to get that thing out
You will definitely need to get the right bottom bracket tool to remove those splined pieces. From what I can see there are 20 splines/teeth. You might have the best luck simply taking it into your LBS to see if they can't remove those pieces for you.
If you are looking to do it yourself, the tool you're looking for probably resembles this guy...
I'm not saying this is the right tool, but it should look similar...not sure what the diff. b/w Freewheel vs BB tools are...etc
Your imaginary friend.
Have you tried twisting it? Probably need some lube. I've never had euro BBs but it is probably left-tight, right-loose.
Every passing minute is another chance to turn it all around.
