Hello all, just signed up for these forum's after almost an hour of confusion. Found that this forum seems to answer a lot of question's for people. I tried browsing threw the search funtion put couldnt come across anything related to what I need. Forgive me if it's allright posted. I used to BMX for about 2-3 year's, then after a bad fall, I simply put it next to my shed in the backyard and neglected it for almost a year in a half. I now wish to rebuild it. I am stuck at the crank's though. I recently purchased a set of the 3-Peice 180mm Eastern Pro Cranks. Being my bike originally had a 3-peice crank, and I had bought it as a complete, I am clueless as to replacing crank's. There is no assembly instruction's, Eastern has not replied to my e-mail's, and I dont want to spend $15 to have my local bike shop put it in. I have looked at various picture's and what not, but can not figure it out...I understand how the basic layout of it is, but there's about 10 washers for this thing, and I dont know where they have to go or the supposed direction of other peices. Can anyone help me out? anything would be appreciated.

Yeah. I'll move it. But I don't know if you'll have any luck there, either.

you'll need to give us some more info, ideally a pic of everything

some pointers - the big tube spaces the bearings, the washers space the arms so they don't hit the chain stays

Dooley, that link kinda sucks. The Park Tools (http://www.parktool.com/repair/readhowto.asp?id=143) one is much better.
