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
