alright, heres the deal.
i just got this pretty sweet sekine, but i have allot of questions about it.
first off i wanna get rid of the cranks, but it doesnt use a crank puller, it uses some bolt through the crank arm by the base of it. i was told to take the bolt out and just hammer it out (its an older sekine) but i just ended up bending it.

You'll need to bend the pin straight again with a hammer, or cut it with a dremmel.. Then tap it out with a hammer and a punch (basically a 3 dollar tool that looks like a pencil made of steel that will allow you to punch that bad boy out)

hahaha ok thank you

holy ****

ok question number 2
i really dont want this reflector piece on my bike, but i have no idea how to get the top of that headset off.
it looks like i need a special tool or something?



and question number 3
alright even after i take the bolt out of my stem it still doesnt want to come out, like at all.
i have a picture here of the bolt, i dont know if it'll really help. anyone think they know why? (other picture of it in question number 2)

for 3, tap that bolt down, it will push the quill down and let the stem loose.

screw it back in, unscrew it just a little bit and tap it with a hammer. then it will come out.

Don't tap on it slowly, that will mushroom or bend the pin. Instead when you start to hammer the cotter pin, give real good thor hits and it should pop out.

For two I'd probably get a lock ring tool, Mine is a hozen 13 bucks. Like the same thing that unlocks your lockring on the cog.. That's what it looks like to me..Also you could try the piper wrench if you don't mind scratching it..But get the lock ring remover...

i sort of get what you guys are saying
but im not 100%

To solve Number 2 you must first solve Number 3. Once that is solved, you take the stem all the way out and use a headset wrench (or a big wrench from your dad's tool chest) to take off the headset nuts and then slide that refelctor thingy off.

Here is what a headset wrench looks like: https://www.mec.ca/Products/product_d...=1233934534193


Sekines can be pretty decent bikes, I found one in a scrap yard and gave it to a friend and he loves it.

Tapping the bolt will release the slider portion of the quill, but if it's an old bike that hasn't been maintained, the stem may still be seized up in the steerer.
If that's the case, straddle the front wheel, grab hold of the bars and wiggle the stem loose while holding the front wheel steady with your legs.
