BMX - taking out a fork

hi im pretty new at bmx, so i was wondering if i could get some help. I just got a new fork and i want to take out my old one. I have a gyro, if that helps.

Threaded or unthreaded? That is the question. You still won't be able to swap the forks yourself unless you get creative with the crown race since it is press-fitted on the fork. But if you really want to have a go, just unscrew everything in that area and you should start to figure it out. You can't really brake much unscrewing, just be careful of the bearings.

You do realize that you can knock that off with a hammer and a punch, right?

yeah, I did that once, It works. I went and used a steel pipe cemented into someones yard to put it on again. I just figured it was more work than he was willing to do.

More work? It takes less than a minute to get done.

yeah, but it takes a bit more skill than using an allen key or screwdriver

how can i tell if its threaded or unthreaded?

Well you can look at the stem and tell. If the stem goes into the steerer than it's threaded (there will also appear to be big nuts at the top of the head tube). threadless just clamp on with a few bolts to the steerer. So to take off a threaded stem you would just need to loosen the bolt on the top of the stem while on a threadless you have to take off the bolt on top and then loosen the bolts on the back of it as well.

here i'll take a picture of it and post it cause im the biggest idiot when it comes to technical stuff

sounds good

heres the top of the fork, i have no clue what to really take a picture of

it looks pretty threadless to me. You should be able to just whack the top of that tube with a hammer and it should just fall out. you might want to put a peice of wood or something on the tube so you don't mess it up by hitting it.

thanks im gonna go try that now

You are going to get a lot of crap all over the place, bearing, gyro parts, spacers, etc. try to keep them in order if at all possible.

SUCCESS thank you guys so much

excellent

i have one more question tho, how much of a difference is a 3/8 than a 14 mm

3/8 is 10mm

**** i think i ordered a 3/8 fork and i have a 14mm axle

Well, you can either fix the order before it's shipped, file the dropout slots to 14mm (which will void the warranty, if they're S&M or Odyssey), or buy hub with a 3/8" axle and lace it to your existing rim.

im gettin a friend to rethread the axles or something that will make them fit so i think its ok

You can't rethread a 14mm diameter axle to fit a 10mm (3/8") slot. It doesn't work that way.

i'll make it work

but you can saw the axle or buy a flat axle

saw the axle hmm?

just get a flat axle

how much are they?

same price as any other axle for the same hub

You can't rethread a 14mm diameter axle to fit a 10mm (3/8") slot. It doesn't work that way.
what about using a strip sander or something to "slot" or flatten the axles like Sun does with some of their wheels...or cant you just buy a slotted axle? and the once you slotted the axle use a die/tap to make sure the threads are clean?

Just file the fork dropouts to make them bigger. That's what I did. (i think)

yea, so they break
